Quick answer
The NSW Housing Pattern Book is a catalogue of architect-designed, government-endorsed home designs published by Government Architect NSW: 8 low-rise patterns (semi-detached, terraces, manor houses and townhouses, released July 2025) and 9 mid-rise apartment patterns (3 to 6 storeys, released November 2025). Low-rise patterns can be approved as complying development under the Pattern Book Development Code (Part 3BA of the Codes SEPP), which a registered certifier or council must determine within 10 days under the Regulation, with no DA. Mid-rise patterns go through a streamlined DA, not a CDC.
To use the 10-day pathway the land must be zoned R1, R2 or R3, the housing type must be permissible with consent under an environmental planning instrument, the lot must meet any minimum lot size for that housing type (a test switched off inside a low and mid rise housing area), the land must be clear of the complying development exclusions, and the development must follow the pattern. The Pattern Book Development Code adds absolute exclusions of its own, including bush fire prone land, flood control lots and battle-axe lots. The low-rise designs sold for $1 per lot until 31 January 2026 and are now $1,000 per lot; the mid-rise designs were $1,500 or $2,500 per lot under an introductory offer that ended on 31 May 2026. Design cost is the small part: certification, engineering, BASIX, landscape and construction are priced like any other new home.
Key takeaways
- Buying a pattern does not mean your site qualifies for the fast-track pathway. The design is public; the eligibility test is site-specific. Check the site before you buy the pattern, not after.
- The 10-day CDC applies to the 8 low-rise patterns only. The 9 mid-rise apartment patterns are designed to speed up the DA, not replace it.
- Every low-rise pattern has two versions: a compact version for low and mid rise housing areas (land within 800 m walking distance of a listed station or a mapped town centre) and a version for other sites across NSW. Confirm which one the site calls for before anything is drawn.
- Patterns are adaptable within defined parameters: materials, some internal layouts, orientation and certain dimensions can change; move outside the parameters and it is no longer pattern book development.
- The pathway is working: by late January 2026 the NSW Government reported eight pattern homes approved to start construction, in Gymea, Cronulla, Corrimal, Engadine, Chipping Norton, Carlton and Baulkham Hills.
- A pattern saves the architect’s fee and months of assessment. It does not remove the need for a certifier, an accredited designer’s statement confirming the pattern, structural engineering, BASIX, critical stage inspections and an Occupation Certificate.
What the NSW Housing Pattern Book is
A pattern book is an old idea: a published set of house designs that anyone can build from. Much of Federation-era Sydney was built from pattern books. The NSW Government revived the idea in 2025 as one plank of its housing reforms, alongside the Low and Mid-Rise Housing Policy, the Transport Oriented Development program and the proposed targeted assessment pathway. The Pattern Book’s job is to remove two of the slowest and most expensive steps in delivering small-scale housing: paying for a bespoke architectural design, and waiting months for a merit-based council assessment of it.
The book is published by Government Architect NSW and the Department of Planning, Housing and Infrastructure. Each pattern is a resolved design by a named architectural practice, and some, such as the terraces by Other Architects and by Officer Woods, are winning schemes from the 2024 international design competition. Each pattern sets out its own development standards, location requirements, technical drawing set and technical information, and the NSW Housing Pattern Book Landscape Guide is included with each purchase. The Government states that all low-rise patterns are designed to meet the Australian Building Codes Board’s Livable Housing Design Standard.
There are two halves:
- Low-rise patterns (published July 2025, with the complying development pathway applying from 30 July 2025): 8 designs for semi-detached dwellings, terraces, manor houses and row homes. They are generally two storeys, and some offer a third-storey room or roof terrace as an option. These are the patterns with the complying development pathway.
- Mid-rise patterns (released 24 November 2025): 9 apartment building designs from 3 to 6 storeys for small, corner and large lots. These are assessed by DA under Chapter 7 of the Housing SEPP, which refers to mid-rise patterns published in November 2025 and April 2026.
By late January 2026 the NSW Government reported more than 21,000 pattern designs purchased, by buyers in 24 countries. The number that matters for Sydney owners and builders is smaller and more useful: how many have become approvals, and what it took. That is what the rest of this guide covers.
The Pattern Book is the best thing to happen to small-lot housing approvals in NSW in a decade, and the most misunderstood. The design is the easy, cheap, public part. The pathway is the valuable part, and it depends entirely on the site. We have already seen patterns bought for $1 and then sent to a DA because nobody checked the lot width, the zone or the heritage map first. A pattern is a design, not an approval.
The 8 low-rise patterns
The low-rise book covers the housing types that the Low and Mid-Rise Housing Policy and the Low Rise Housing Diversity Code were written to deliver. Each pattern comes in two versions: a compact version for low and mid rise housing areas and a version for other sites across NSW. The table groups them by housing type and names each pattern as the Pattern Book Development Code identifies it.
| Housing type | What it is | Patterns named in the Code | NSW land use term | Fast-track pathway |
|---|---|---|---|---|
| Semi-detached / duplex | Two attached dwellings side by side, each with its own frontage and yard | Semis 01 by Anthony Gill Architects; Semis 02 by Sibling Architecture | Dual occupancy (attached) | Pattern Book Development Code CDC |
| Terraces | Three or more attached dwellings facing and aligned along the street, each on its own lot or strata | Terraces 01 by Carter Williamson; Terraces 02 by Sam Crawford Architects; Terraces 03 by Officer Woods Architects; Terraces 04 by Other Architects x NMBW (which can include a secondary dwelling) | Multi dwelling housing (terraces) | Pattern Book Development Code CDC |
| Manor house | Three or four dwellings in a single two-storey building that reads as one large house, with at least one dwelling above another | Manor Homes 01 by Studio Johnston | Manor house | Pattern Book Development Code CDC |
| Townhouses / row homes | Attached dwellings, typically arranged along a shared driveway | Row Homes 01 by SAHA | Multi dwelling housing | Pattern Book Development Code CDC |
What matters at certification is that the development must be carried out in accordance with four things in the chosen pattern: its development standards, its location requirements, its technical drawing set and its technical information. All four are site-checked by the certifier, and all four are where a pattern project either stays on the pathway or falls off it.
Several of these housing types also qualify as complying development under the existing Low Rise Housing Diversity Code. The difference is in what the application has to prove. A Low Rise Housing Diversity Code application needs a design statement explaining how the design meets the Low Rise Housing Diversity Design Guide. A Pattern Book Development Code application does not; instead it needs a written statement from an accredited designer (a registered architect or a building designer accredited by the Building Designers Association of Australia) naming the pattern and confirming the development complies with it.
The 9 mid-rise patterns
The mid-rise patterns are apartment buildings of 3 to 6 storeys, approved through a development application under Chapter 7 of the Housing SEPP. Residential flat buildings must already be permitted with consent on the land under an environmental planning instrument. The small lot and corner lot patterns can be used only on Transport Oriented Development land or in a low and mid rise housing area; the large lot patterns are not limited in that way. Chapter 7 does not apply to some land at all, including bush fire prone land, heritage items, heritage conservation areas and four excluded local government areas. The patterns were released on 24 November 2025 at an introductory price of $1,500 per lot for small-lot and corner-lot designs and $2,500 per lot for large-lot designs, against standard prices of $15,000 and $25,000 per lot, with the offer running to 31 May 2026.
| Lot type | Number of patterns | Storeys | Designed for | Approval pathway |
|---|---|---|---|---|
| Small lot | 4 | 3 to 6 | Infill sites on TOD land or in a low and mid rise housing area | DA under Housing SEPP Chapter 7 |
| Corner lot | 2 | 3 to 6 | Sites with two street frontages, on TOD land or in a low and mid rise housing area | DA under Housing SEPP Chapter 7 |
| Large lot | 3 | 3 to 6 | Larger or amalgamated sites where residential flat buildings are permitted | DA under Housing SEPP Chapter 7 |
Two things to understand before buying a mid-rise pattern. First, there is no complying development pathway for mid-rise: the pattern is a head start on the DA drawings and the design-quality argument, not on the assessment itself. Second, the pattern does not remove the need for site-specific work: the consent authority still determines the application, so a planning review and a BCA design assessment are still needed before lodgement. The mid-rise patterns are, in practice, a tool for developers and builders who already understand the DA process, not for owner-builders.
How the Pattern Book Development Code works (the 10-day CDC)
The Pattern Book Development Code is Part 3BA of the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008 (the Codes SEPP). It has applied since 30 July 2025, supported by amendments to the Environmental Planning and Assessment Regulation 2021, and it does one thing: it makes a low-rise pattern book development, on an eligible site, complying development that a registered certifier or council can approve with a Complying Development Certificate.
Because the design has already been assessed for quality and the development standards are written into the code, the certifier’s assessment is confined to confirming that the site is eligible, the exclusions do not apply, the design matches the pattern within its allowed parameters, the pattern-specific standards are met, and the construction documentation complies with the National Construction Code. The Regulation backs that with a fixed period: a Pattern Book Development Code application must be determined within 10 days. Other complying development is also 10 days, or 20 days where the neighbour notification rules apply, which covers most new dwellings in metropolitan Sydney. A pattern application stays at 10 days even where those rules apply, with a 7-day neighbour notice period instead of 14.
In practice the pathway runs like this:
- The owner or builder purchases the pattern from the Planning NSW portal, choosing the compact version or the version for other sites, whichever the site calls for.
- The site is checked for eligibility and exclusions (the next section).
- The pattern is adapted within its parameters, and the supporting documents are prepared: survey, site plan, BASIX, structural engineering, stormwater, landscape documentation using the Landscape Guide supplied with the pattern, any specialist reports the site triggers, and the accredited designer’s statement confirming the pattern and its compliance.
- The CDC application is lodged on the NSW Planning Portal and assessed by the certifier under Part 3BA.
- Where the neighbour notification rules apply, the certifier must give neighbours and the council at least 7 days’ written notice before issuing the CDC.
- The CDC issues; the Principal Certifier is appointed; construction, mandatory inspections and the Occupation Certificate follow as for any CDC project.
The 10-day figure is the certifier’s determination on a complete, eligible application. It is not the time from buying a pattern to starting construction; the documentation stage in step 3 takes several weeks and is where most of the real work sits.
The eligibility test: does your site qualify?
The availability of a pattern and the availability of the pathway are different questions. The pattern is for sale to anyone. The pathway is available only where the site passes four tests drawn from Part 3BA and the general complying development requirements of the Codes SEPP.
| Test | What it requires | Where to check | Common failure |
|---|---|---|---|
| 1. Permissibility | The land must be zoned R1, R2 or R3, and the housing type (dual occupancy, manor house, multi dwelling housing or terraces) must be permissible with consent under an environmental planning instrument: the council’s LEP or Chapter 6 of the Housing SEPP (dual occupancies in R2, and multi dwelling housing in R2 inside a low and mid rise housing area) | LEP land use table; Housing SEPP Chapter 6 | Land zoned R4; multi dwelling housing or terraces prohibited by the LEP in R2 on a site outside a low and mid rise housing area |
| 2. Lot size and dimensions | The lot must meet any minimum lot size for that housing type under an environmental planning instrument, unless it is in a low and mid rise housing area, where that test does not apply. It must have lawful access to a public road on completion, and the pattern’s location requirements must be met | LEP lot size map; the pattern’s location requirements | Frontage too narrow for the pattern’s location requirements; the LEP minimum for the housing type not met outside a low and mid rise housing area |
| 3. Design conformity | The development must be carried out in accordance with the pattern’s development standards, location requirements, technical drawing set and technical information, using the version that matches the site, and the application must include an accredited designer’s statement confirming it | Pattern documents; DPHI’s Guidance for low-rise pattern book users | Changes the pattern does not offer as an option: a different footprint, roof form or number of dwellings |
| 4. Exclusions | The general complying development exclusions in the Codes SEPP (including heritage items and draft heritage items, heritage conservation areas and environmentally sensitive land), plus the Pattern Book Development Code’s own exclusions: bush fire prone land, flood control lots, battle-axe lots, lots with an existing secondary dwelling or group home, building over a registered easement, unsewered land and land identified as susceptible to landslide risk | Section 10.7 planning certificate; LEP heritage and hazard maps; title search | Heritage conservation area; bush fire prone land or a flood control lot |
The exclusions that catch people out are the Code’s own. Under the Low Rise Housing Diversity Code, dual occupancies and manor houses on bush fire prone land (other than BAL-40 or Flame Zone), and development on the certified parts of a flood control lot, can still be complying development if extra standards are met. Under the Pattern Book Development Code, bush fire prone land and flood control lots are excluded outright. The same lot can therefore be eligible under one code and not the other. Both codes exclude battle-axe lots and lots that already have a secondary dwelling. Some commentary from 2025 also describes an exclusion for R2 dual occupancies that rely on the Housing SEPP for permissibility; no such exclusion appears in the Code as currently in force. Where neither code fits, the next step is planning advice.
The practical sequence is: section 10.7 certificate first, LEP zoning and lot size second, low and mid rise housing area third, exclusions fourth, pattern version fifth. Thirty minutes of that work, done before the pattern is bought, is the difference between a 10-day CDC and a DA. Our pathway confirmation service exists for exactly this.
Low and Mid-Rise Housing areas vs the rest of NSW
Every low-rise pattern has two versions, and which one you can use depends on whether the site is inside a Low and Mid-Rise Housing area under Chapter 6 of the Housing SEPP. A low and mid rise housing area is land within 800 metres walking distance of land identified as a Town Centre on the Housing SEPP Town Centres Map, or of a public entrance to a railway, metro or light rail station listed in Schedule 11 of that policy. The listed stations are in metropolitan Sydney and the Hunter, and mapped town centres extend the areas further, so check the Town Centres Map for the site. Chapter 6 does not apply to some land at all, including bush fire prone land, heritage items, four named local government areas and land on the exclusion map.
| Factor | Inside a low and mid rise housing area | Outside (rest of NSW) |
|---|---|---|
| Pattern version | Compact version | Version for other sites |
| Permissibility | Dual occupancies permitted in R2 under Chapter 6; multi dwelling housing also permitted in R2, even where the LEP prohibits it | Dual occupancies permitted in R2 under Chapter 6 on land to which that chapter applies; other housing types only where the LEP permits them in the zone |
| Lot size test | Minimum lot size under other instruments switched off; the pattern’s location requirements still apply | Any minimum lot size for the housing type must be met, plus the pattern’s location requirements |
| Development standards | The pattern’s development standards. The Housing SEPP’s non-discretionary standards for low and mid rise housing apply to development applications, not to a CDC | The pattern’s development standards |
Confirming the status of a site is not a radius on a map. Walking distance is measured along the shortest route that can be safely walked, using public footpaths and pedestrian crossings as far as reasonably practicable, and an exclusion map removes further land. Departmental maps are a useful guide, but the instrument is the test, so expect a planner or certifier to check the route lot by lot. Our dual occupancy rules guide walks through the same test for a single housing type.
What you can change in a pattern, and what you cannot
A pattern is not a fixed plan to be built identically on every site. Each low-rise pattern incorporates flexible features that can be modified within defined parameters, so that it can be adapted to orientation, slope, household size and budget. The parameters are set out in the pattern documentation and in DPHI’s Guidance for low-rise pattern book users. Exceed them and the development is no longer “in accordance with a pattern” for the purposes of Part 3BA, which means the CDC pathway closes.
| Element | Generally allowed within parameters | Generally not allowed (takes the project out of pattern CDC) |
|---|---|---|
| External materials and colours | Selection from the pattern’s material palette and equivalent alternatives | Changes that alter the articulation, fenestration pattern or roof form the design relies on |
| Orientation and mirroring | Mirroring and rotation to suit the lot and solar access | Siting outside the setbacks or building envelope the pattern standards set |
| Internal layout | Optional room configurations the pattern provides (for example a study or an extra bedroom in a defined zone) | Structural changes to the plan, moving wet areas outside the defined zones, changing the number of dwellings |
| Floor area and storeys | The size options the pattern offers, which for some patterns include a third-storey room or roof terrace | Floor area, storeys or a basement the pattern does not offer |
| Garages and parking | The parking configurations the pattern offers | Additional garages, front-of-lot parking the pattern does not allow |
| Landscape | Species and detail choices within the Landscape Guide supplied with the pattern | Departures from the landscape and open space requirements in the pattern |
| Accessibility | Nothing to change: the patterns are designed to the Livable Housing Design Standard | Removing step-free entry or accessible bathroom provisions |
The table is a general guide; the pattern documents and the Department’s guidance set the actual options. The rule of thumb our certifiers use: if the change is one the pattern documentation anticipates and gives you an option for, it is a modification. If it is a change you would need an architect to redraw, it is a new design, and it should be assessed as a Low Rise Housing Diversity Code CDC or a DA from the start rather than lodged as a pattern and refused.
Send the certifier the pattern, the version you intend to use and a one-page list of the changes you want before anyone draws them. A pre-lodgement review takes a day and tells you whether the project is still pattern book development. Built Smart Solutions includes this in every CDC fee proposal for a pattern project.
Pattern Book CDC vs Low Rise Housing Diversity Code vs DA vs bespoke
A pattern home is one of four ways to deliver two-storey infill housing on a Sydney lot. The right one depends on the site, the design ambition and the appetite for time and risk.
| Factor | Pattern Book Development Code CDC | Low Rise Housing Diversity Code CDC | Development application (DA) |
|---|---|---|---|
| Design | Government Architect-endorsed pattern, adapted within parameters | Bespoke design meeting every code standard and the Low Rise Housing Diversity Design Guide | Bespoke design assessed on merit |
| Who approves | Registered certifier or council | Registered certifier or council | Consent authority (usually the council or a local planning panel) |
| Determination period | 10 days | 10 days, or 20 days where neighbour notification applies (most new dwellings in metropolitan Sydney) | 40-day assessment period, after which the application is deemed refused for appeal purposes only; the consent authority can still determine it, and many take longer |
| Design cost | Fixed pattern price ($1,000 per lot for low-rise) plus adaptation drafting | Bespoke design by an architect or building designer, priced against the brief | Bespoke design, plus a planner and Statement of Environmental Effects |
| Design-quality assessment | Accredited designer confirms compliance with the pattern | Design statement against the Low Rise Housing Diversity Design Guide | Consent authority assesses on merit |
| Flexibility | Low: within pattern parameters | Medium: any design that meets every standard | High: variations on merit |
| Neighbour objection rights | None (notification only, where the rules apply) | None (notification only, where the rules apply) | Submissions considered on merit |
| Best for | Standard lots, owners and small builders who want speed and certainty | Standard lots with a bespoke design that fits the code | Constrained sites, non-compliant designs, ambitious architecture |
The pattern pathway wins on speed, design cost and certainty. The Low Rise Housing Diversity Code wins where you want your own design and it fits the standards. The DA is for everything else. A targeted assessment pathway for low-rise housing has been proposed by the Department but is not law, and the variation certificates for complying development provided for by a 2025 amendment to the Act have not commenced, so neither is a pathway a client can choose today. Our note on the fast-track assumption explains why the pathway decision comes before the design decision on every one of these.
What a pattern book project costs, and what actually moves the number
The design is the only fixed price on a pattern book project. The low-rise patterns are $1,000 per lot (they were $1 per lot until 31 January 2026), and the mid-rise patterns are $15,000 or $25,000 per lot after an introductory offer of $1,500 or $2,500 that ended on 31 May 2026. Confirm the current price on the Planning NSW portal before you buy. Everything after the purchase is priced against the site and the scope, and a figure quoted without the site behind it tells you very little. What follows is what sets the rest of the budget, and what a proposal has to state before you can compare one to another.
| Factor | Why it moves the cost |
|---|---|
| The site | Survey, stormwater and civil design, and any geotechnical, arborist or acoustic input are driven by the land: its slope, drainage, trees and surroundings. |
| How much adaptation the pattern needs | Siting the pattern, choosing its options and documenting it for the lot, including the accredited designer’s statement the Regulation requires. The closer the lot is to the pattern’s assumptions, the less drafting there is. |
| Number of dwellings | Structural engineering, BASIX (each dwelling must be covered by a BASIX certificate) and certification all scale with the number of dwellings. |
| Building class and inspections | The critical stage inspections are set by the Regulation for the building’s class. More stages means more site attendance. |
| Council contributions | Section 7.11 contributions and section 7.12 levies are set by the council’s contributions plan and vary widely between LGAs. Where the plan applies, the CDC must require payment before work starts. |
| Long Service Levy | Statutory: 0.25% of the cost of works where the works cost $250,000 or more, paid before the CDC is released. |
| Separate titles | Torrens subdivision adds a surveyor, a subdivision certificate and registration. |
| Government fees | Lodgement, certificate and agency fees are set by government and change from time to time, so a proposal should list them as pass-through items rather than build them into the fee. |
What a comparable proposal has to tell you
- Which pattern, on which lot. The pattern and options proposed, and confirmation that the land is clear of the Pattern Book Development Code exclusions before anything is drawn.
- What the fee covers. The CDC, the Principal Certifier appointment, each critical stage inspection and the Occupation Certificate, listed separately.
- What it excludes. Survey, engineering, BASIX, landscape, contributions, the Long Service Levy and government fees, stated as excluded rather than simply left out.
- Who prepares the accredited designer’s statement. The CDC cannot be issued without it.
- What happens if something changes. The terms for re-inspections, design changes and additional information requests.
- The turnaround. When the CDC will be determined once the application is complete.
- A fixed fee against that scope, rather than an hourly rate with no cap.
Built Smart Solutions quotes every engagement as a fixed fee against a written scope, with the exclusions and the turnaround stated on the same page. Get a fee proposal.
The pattern replaces the bespoke design and, because the pathway is a CDC, the planner and Statement of Environmental Effects a DA would need. Nothing else gets cheaper: engineering, certification, contributions and construction are what they would be for any two new dwellings.

Timeline: from pattern purchase to Occupation Certificate
| Stage | Duration | What happens |
|---|---|---|
| Eligibility and pathway review | A few days | 10.7 certificate, zoning, lot size, low and mid rise housing area, exclusions, pattern version |
| Pattern purchase and adaptation | Usually a few weeks | Pattern downloaded; options selected; site plan, survey and documentation drafted |
| Engineering, BASIX, landscape, specialist reports | Usually a few weeks, overlapping with adaptation | Site-specific certification of the pattern design |
| Certifier pre-lodgement review | A few days | Deficiencies found before the statutory clock starts |
| CDC lodgement, notification and determination | 10 days | The Regulation’s determination period for Part 3BA; any 7-day neighbour notice runs within it |
| Principal Certifier appointment and Notice of Commencement | At least 2 days before work starts | Notice to the council and the principal certifier; neighbours also receive notice of commencement as a condition of the CDC (7 days in most of Sydney) |
| Construction, with the critical stage inspections set for the building’s class | Depends on the design and the builder | For a class 1 building: footing excavation, in-situ concrete, framework, wet area waterproofing, stormwater, final |
| Occupation Certificate | Once the final inspection is passed and the compliance certificates are in | Compliance certificates reviewed, OC issued |
| Total to approval | Usually a matter of weeks | Indicative, on an eligible site with a complete application |
Uptake so far and what the early projects show
In late January 2026, as the $1 low-rise offer was closing, the NSW Government reported more than 21,000 pattern designs purchased, by buyers in 24 countries, and eight pattern homes approved to start construction, in Gymea, Cronulla, Corrimal, Engadine, Chipping Norton, Carlton and Baulkham Hills. In the same week Landcom began building seven terraces by Other Architects at Edmondson Park, expected to be complete in early 2027.
Two things stand out from those numbers. The gap between more than 21,000 purchases and a handful of approvals at that point shows how many buyers were browsing rather than building, and how many sites will turn out not to qualify. And the spread of early approvals across the Sutherland Shire, the Illawarra, south-west Sydney, the St George area and the Hills shows the pathway working on ordinary suburban lots.
Our own Sutherland Shire dual occupancy case study pre-dates the Pattern Book but is the same lesson: confirm the pathway, lodge complete, and the fast track is fast.
Common mistakes that knock pattern projects out of the fast track
Buying the pattern before checking the site
The pattern is public; the pathway is site-specific. Frontage, zoning, lot size, heritage, bushfire and flood mapping are all knowable before the purchase.
Using the wrong version
The compact version is for low and mid rise housing areas; the other version is for everywhere else. A design that does not meet the location requirements for the site is not in accordance with the pattern, and the certifier cannot issue the CDC.
Treating the pattern as a starting point for redesign
Once the changes go beyond the pattern’s parameters it is a bespoke design, and it should be assessed as one. Lodging it as pattern book development wastes the application fee and the certifier’s time.
Forgetting the designer’s statement
A Pattern Book Development Code application must contain a written statement from an accredited designer naming the type of development and the pattern, and confirming the development will comply with the pattern’s development standards, location requirements, technical drawing set and technical information. Without it the application is incomplete.
Assuming the pattern is engineered for the site
The pattern is a design. Structural, stormwater and, where triggered, bushfire and flood certification are site-specific and the certifier cannot issue without them.
Ignoring contributions
Section 7.11 or 7.12 contributions apply to complying development where the council’s contributions plan provides for them, and must be paid before work starts. On a two-dwelling project they can exceed every other approval cost combined.
Changing the design on site
A window moved, a wall shifted or a roof pitch changed during construction can take the building outside the pattern. Why minor site changes stop projects.
Expecting a mid-rise CDC
There is none. The mid-rise patterns go to a DA, and the DA still needs a planner, a BCA review and, usually, a fire safety strategy.
How to get a pattern book home approved: step by step
Check the site before you buy
Obtain the section 10.7 certificate. Confirm the zone, any minimum lot size for the housing type, whether the site is in a low and mid rise housing area, and whether any exclusion applies, including bush fire prone land and flood control lots. Confirm the lot frontage and depth against the pattern’s location requirements.
Choose the pattern and the version
Select the housing type the site permits and the version (compact for low and mid rise housing areas, the other version elsewhere). Purchase it from the Planning NSW portal.
Confirm the pathway with a certifier
A pre-purchase or pre-design review confirms Part 3BA eligibility in writing and lists the documents the CDC will need. If the site fails, this is where you learn it, for a few hundred dollars.
Adapt within parameters and document
Commission the survey, site plan and adaptation drafting; select the pattern’s options; obtain structural, stormwater, BASIX, landscape documentation, any triggered specialist reports and the accredited designer’s statement.
Pre-lodgement review, then lodge complete
Have the certifier review the full set before lodgement so the 10-day period runs on a complete application. Lodge on the NSW Planning Portal under the Pattern Book Development Code.
CDC, Principal Certifier, Notice of Commencement
On determination, appoint the Principal Certifier, give the council at least 2 days’ notice before work starts, and give neighbours the notice of commencement the CDC requires. Diarise the critical stage inspections with the builder.
Build to the pattern, then Occupation Certificate
Any proposed site change is checked against the pattern parameters before it is built. At completion the certifier reviews the compliance certificates and issues the OC, and a subdivision certificate if the dwellings are being separately titled.
Who the Pattern Book is for, and who should go bespoke
| Use a low-rise pattern when | Go bespoke (LRHDC CDC or DA) when |
|---|---|
| The site is a standard suburban lot that passes the four eligibility tests | The site is constrained: heritage, steep, irregular, flood or bushfire affected beyond what the code allows |
| You want a two-dwelling or small multi-dwelling outcome at the lowest design cost | You want a design the pattern parameters cannot deliver |
| Speed and certainty of approval matter more than individuality | Individuality matters more than a few months |
| You are an owner, small builder or first-time developer | You are an experienced developer with an architect already engaged |
| Livable Housing Design Standard compliance is a plus (it is built in) | The project is mid-rise: the patterns help the DA but there is no CDC |
Final verdict
The NSW Housing Pattern Book is a well-designed set of homes attached to a well-designed approval pathway, and for the right site it is one of the fastest and lowest-cost routes to new low-rise housing in NSW. The right site is the whole question. Owners who check eligibility first, use the correct pattern version, stay inside the parameters and lodge a complete application are getting CDCs in weeks. Owners who buy the pattern first and ask questions later are getting DAs.
If you own a lot in Sydney or regional NSW and are weighing a pattern home, the first step is not the purchase; it is a half-day of pathway work. Built Smart Solutions can confirm eligibility, review your proposed modifications, issue the CDC under the Pattern Book Development Code and act as Principal Certifier through to the Occupation Certificate, as one team on a fixed fee.

Frequently asked questions about the NSW Housing Pattern Book
What is the NSW Housing Pattern Book?
The NSW Housing Pattern Book is a catalogue of architect-designed, government-endorsed home designs published by Government Architect NSW and the Department of Planning, Housing and Infrastructure. It contains 8 low-rise patterns (semi-detached dwellings, terraces, manor houses and townhouses, released July 2025) and 9 mid-rise apartment patterns of 3 to 6 storeys (released November 2025). Each pattern sets out its own development standards, location requirements, technical drawing set and technical information, and the low-rise patterns can be approved as complying development under the Pattern Book Development Code.
What is the Pattern Book Development Code?
The Pattern Book Development Code is Part 3BA of the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008. It has applied since 30 July 2025 and creates a complying development pathway for low-rise pattern book developments on eligible sites, so a registered certifier or council can issue a Complying Development Certificate without a DA. The Regulation requires the application to be determined within 10 days.
How much do NSW pattern book designs cost?
The low-rise patterns were sold at an introductory price of $1 per lot from July 2025 until 31 January 2026 and are now $1,000 per lot. The mid-rise apartment patterns were released at $1,500 per lot for small-lot and corner-lot designs and $2,500 per lot for large-lot designs until 31 May 2026, against standard prices of $15,000 and $25,000 per lot. A licence covers one building on one site. The design is a small part of the project cost; surveying, adaptation drafting, engineering, BASIX, landscape, certification and contributions are priced like any other new home.
Can I get a CDC for a pattern book home?
Yes, for the 8 low-rise patterns on an eligible site. The land must be zoned R1, R2 or R3 and the housing type must be permissible with consent under an environmental planning instrument. The lot must meet any minimum lot size for the housing type (a test switched off in a low and mid rise housing area) and the pattern’s location requirements. The land must be clear of the complying development exclusions, such as heritage conservation areas, and of the Code’s own exclusions, such as bush fire prone land and flood control lots. The development must follow the pattern. There is no CDC pathway for the mid-rise patterns.
Does buying a pattern mean my project is approved?
No. A pattern is a design, not an approval. Approval under the Pattern Book Development Code depends on the site passing the eligibility tests and on a certifier issuing a Complying Development Certificate. Many purchased patterns are for sites that do not qualify, which is why checking the site before buying is the most important step.
How long does a pattern book CDC take in NSW?
The Regulation requires a Pattern Book Development Code application to be determined within 10 days of lodgement, compared with 20 days for most other new-dwelling CDCs in metropolitan Sydney. A DA has a 40-day assessment period before it is deemed refused for appeal purposes, and many take longer. The time from buying a pattern to lodging a complete application, including survey, adaptation drafting, engineering, BASIX and the landscape plan, usually takes a few weeks.
Can I modify a pattern book design?
Within defined parameters, yes. Each low-rise pattern has flexible features such as material selections, mirroring and orientation, optional room configurations and the size options the pattern offers. Changes outside the parameters, such as adding floor area or a storey the pattern does not offer, changing the footprint or roof form, or altering the number of dwellings, mean the development is no longer in accordance with the pattern and the CDC pathway is not available; it would be assessed as a bespoke design under the Low Rise Housing Diversity Code or a DA.
What is the difference between the two versions of a pattern?
Each low-rise pattern has two versions. The compact version is for sites inside a low and mid rise housing area under Chapter 6 of the Housing SEPP, which is land within 800 metres walking distance of a listed railway, metro or light rail station or a mapped town centre. There, minimum lot size requirements in other instruments do not apply, although the pattern’s location requirements do. The other version is for sites elsewhere in NSW, where any minimum lot size for the housing type must also be met.
Can I use a pattern book design for a dual occupancy in an R2 zone?
Yes, if the other tests are met. The Pattern Book Development Code applies in R1, R2 and R3, and complying development only needs the dual occupancy to be permissible with consent under an environmental planning instrument. Chapter 6 of the Housing SEPP permits dual occupancies in R2 on land to which that chapter applies, so a council LEP that prohibits them in R2 is not the end of the question. Some commentary from 2025 describes an exclusion for R2 dual occupancies that rely on the Housing SEPP; no such exclusion appears in the Code as currently in force. The lot must still meet any minimum lot size for dual occupancies (unless it is in a low and mid rise housing area) and avoid the exclusions.
Do pattern book homes need a certifier, engineer and BASIX?
Yes. The pattern provides the architectural design, but the CDC requires a site survey, structural and stormwater engineering certified for the site, a BASIX certificate for each dwelling, landscape documentation, any specialist reports the site triggers, a written statement from an accredited designer confirming the pattern, and a registered certifier to assess and issue the CDC. A Principal Certifier must then be appointed, mandatory inspections carried out and an Occupation Certificate issued, as for any new home.
Are the mid-rise pattern book designs complying development?
No. The 9 mid-rise apartment patterns sit in Chapter 7 of the Housing SEPP and are approved by development application. The Department describes the pathway as streamlined because matters already resolved in the pattern do not need to be assessed again, but the consent authority still determines the application and there is no CDC pathway. A planning review, BCA design assessment and fire safety strategy are still required before lodgement.
Do section 7.11 or 7.12 contributions apply to pattern book CDCs?
Yes, where the council’s contributions plan provides for a section 7.11 contribution or section 7.12 levy for that type of development. The CDC must then carry a condition requiring payment before work starts. The amount is set by the council’s plan and varies widely between LGAs, so check the plan that applies to the land and put the figure in the budget from day one.
How many pattern book homes have been approved in NSW?
In late January 2026 the NSW Government reported eight pattern homes approved to start construction, in Gymea, Cronulla, Corrimal, Engadine, Chipping Norton, Carlton and Baulkham Hills, and more than 21,000 pattern designs purchased. Landcom also began building seven terraces by Other Architects at Edmondson Park at that time. Check the Planning NSW website for later figures.
Can Built Smart Solutions certify a pattern book home?
Yes. As registered certifiers across Sydney and regional NSW, Built Smart Solutions confirms Pattern Book Development Code eligibility, reviews proposed modifications against the pattern parameters, issues the Complying Development Certificate under Part 3BA, acts as Principal Certifier through construction and issues the Occupation Certificate, as one team on a fixed fee.
