Residential Livability
Clear guidance on the livable housing requirements that may apply to a dwelling, and the design review or assessment pathway required.
For homeowners, architects, building designers, builders and developers coordinating project-specific livability requirements during design and documentation.
Send Your Project for ReviewIn Brief
Livable Housing Design addresses residential features that make a dwelling easier to enter, move through and use as household needs change over time. Depending on the applicable jurisdiction and project pathway, this may include step-free entry, suitable thresholds, door and corridor widths, internal circulation, usable toilet and bathroom layouts, and structural reinforcement for future grabrails.
The requirements applying to a project can depend on its location, dwelling type, approval pathway and any relevant planning or project-specific obligations. Reviewing these matters during design can help identify the appropriate livable-housing pathway before entries, floor levels, circulation spaces and sanitary facilities are fixed in the documentation.
A Livable Housing Design review focuses on residential usability, relevant jurisdictional provisions and the documentation needed to support the project. It does not replace broader NCC review or separate specialist advice where additional project requirements apply.

Foundation
Livable Housing Design is the practice of planning dwellings so they are easier to enter, move through and use as household needs change over time. It considers practical residential features such as step-free entry, suitable thresholds, door and corridor widths, internal circulation, usable toilets and bathrooms, and structural provisions that may support future grabrails.
In Australia, the requirements applying to a dwelling may arise through the NCC Livable Housing Design provisions, relevant Livable Housing Design Guidelines, planning controls or project-specific obligations. The appropriate pathway depends on the project location, dwelling type, applicable jurisdictional arrangements and the assessment outcome required.
Good Livable Housing Design is usually integrated early. Entry levels, thresholds, structural layouts, circulation spaces and sanitary facilities can become difficult or costly to revise once the design is advanced. Early review allows these requirements to be coordinated as part of the architecture rather than treated as additions after the plans have been substantially resolved.
In simple terms: Livable Housing Design identifies the residential usability requirements relevant to a dwelling and helps clarify how they should be addressed through design and documentation. It does not replace broader NCC review, specialist access advice or a separate adaptable-housing assessment where required.
Long-Term Usability
Homes are long-term assets, but they are often designed around a short moment in time. Household needs may change as children grow, relatives visit, occupants age, mobility changes or temporary injuries affect everyday movement. Livable Housing Design helps reduce avoidable barriers so a dwelling can remain practical for a wider range of occupants and visitors over time.
The value of livable design is often found in relatively small decisions made early. A step-free entry, suitable threshold, wider doorway, clearer circulation route or usable bathroom layout can improve everyday movement without changing the architectural character of the home. Structural reinforcement and carefully planned spaces may also make future modifications simpler and less disruptive.
Early consideration also helps architects, builders and developers coordinate livable-housing requirements before floor levels, structural elements, room layouts and services are fixed. Where specific jurisdictional or planning requirements apply, design-stage review can reduce the risk of late documentation changes and help identify whether additional specialist pathways are required.
Suitable entries, thresholds and circulation spaces can reduce unnecessary barriers in everyday residential use.
Early spatial and structural provisions can make later household modifications easier to coordinate.
Design-stage review can clarify applicable provisions, documentation needs and any related specialist pathway.
Pathway Boundaries
Livable Housing Design, Residential DTS, Adaptable Housing, Accessible Design and Universal Design can influence the same dwelling, but they do not assess the same requirements or produce the same outcome. The appropriate pathway depends on the project location, dwelling type, planning obligations and the purpose of the review.
Understanding these distinctions helps project teams identify which residential livability requirements apply and whether broader NCC review, a separate adaptable-housing pathway or specialist access advice may also be required.
Broader NCC Pathway
Livable Housing Design focuses on residential usability provisions relating to matters such as entries, thresholds, circulation, doorways and sanitary facilities. These provisions may form part of a broader Deemed-to-Satisfy pathway, but they do not replace review of energy efficiency, condensation management or other NCC requirements.
Explore Residential DTS →Future Adaptation
Livable Housing Design supports everyday residential usability and may include provisions that make later changes easier. Adaptable Housing can involve a separate pathway under AS 4299, including pre-adaptation and post-adaptation layouts, nominated dwelling percentages and project-specific planning requirements. Where these obligations apply, a separate adaptable-housing assessment may be required.
Specialist Access Requirements
Livable Housing Design addresses the usability of dwellings and the residential livability provisions relevant to the project. Accessible Design may involve separate requirements under AS 1428, the Premises Standards and other access provisions covering paths of travel, ramps, stairs, sanitary facilities, tactile indicators and signage. A Livable Housing Design review does not demonstrate compliance with these broader access requirements.
Design Philosophy
Universal Design is a broad design philosophy that seeks to make buildings and environments usable by as many people as practical from the outset. It can inform residential design, but it is not a separate Certified Energy assessment or certification product. Livable Housing Design has a narrower role focused on applicable residential requirements, design review and project documentation.
Scope boundary: A Livable Housing Design review does not replace broader NCC review, specialist access advice or a separate adaptable-housing assessment where those pathways apply.
Residential Performance
Residential performance is often discussed through energy efficiency, thermal comfort, water use and building compliance. Livable Housing Design adds another important layer: how well the home works for the people who use it every day. A home can be efficient on paper but still feel difficult to live in if access, circulation, bathrooms or thresholds have not been carefully considered.
Livable design and energy performance are not separate conversations. A home that is easier to move through, easier to ventilate, easier to maintain and easier to adapt can support better long-term occupation. These qualities become especially important as Australian housing moves toward higher expectations around comfort, electrification, retrofit planning and whole-of-home performance.
This is why Livable Housing Design belongs within a broader residential performance framework. It connects with how homes are planned, how they are assessed, how they are renovated and how they remain useful over time. The best outcomes usually come when livable design is considered alongside other project requirements rather than added late as an isolated compliance item.
Comfortable homes are easier to use when rooms, circulation paths and daily living areas remain practical across seasons.
Energy systems, appliances, layout and usability all shape how well a home performs for occupants over time.
Access, bathrooms, insulation, glazing and services can often be considered together when an existing home is upgraded.
A home performs better when it remains suitable, comfortable and adaptable for changing occupants and household needs.
Design Features
Livable Housing Design is expressed through practical features that make a dwelling easier to enter, move through and use. When these elements are considered early, they can be integrated into the architecture without making the home feel institutional or unnecessarily specialised.
The precise dimensions, locations and documentation requirements depend on the applicable jurisdiction, dwelling type and project pathway. The following areas are commonly reviewed when determining how relevant livable-housing provisions should be addressed.
The approach to the dwelling may need to provide a suitable step-free path between the property entry, parking area or another nominated arrival point and an entrance to the home.
Entrance location, clear opening, landing space, weather protection and threshold detailing may need to be coordinated so the dwelling can be entered with fewer physical barriers.
Internal door openings, corridor widths and the relationship between adjoining spaces are reviewed to support suitable movement through the relevant parts of the dwelling.
Room layouts, door swings, fixtures and circulation zones may need to be coordinated so required spaces remain practical and are not obstructed by the surrounding design.
The location and layout of toilets, showers, doors and sanitary fixtures may be reviewed to provide the required access, circulation and everyday usability.
Relevant toilet and shower walls may require structural reinforcement so grabrails can be installed later without extensive alteration to the completed bathroom.
Project-specific requirements: Not every feature or pathway applies to every dwelling. Applicable dimensions, exemptions, variations and documentation should be confirmed against the relevant jurisdiction and project brief.
Project Pathways
The Livable Housing Design pathway applying to a dwelling depends on the project location, building classification, dwelling type, approval pathway and any relevant planning or project-specific requirements. For some projects, the applicable provisions arise through the National Construction Code. Other projects may need to respond to planning controls, development conditions, client requirements or an identified Livable Housing Design Guidelines level.
Pathway clarification should occur before entries, floor levels, door openings, circulation spaces, sanitary facilities and structural provisions are fixed. A design-stage review can help identify the relevant requirements, test the proposed plans and clarify what information should be shown in the architectural and supporting documentation.
The required outcome may range from design advice and plan review through to documentation supporting a particular project pathway. Where the brief also requires an AS 4299 adaptable-housing assessment, specialist access advice or broader NCC review, those matters should be identified and coordinated as separate scopes.
Applicability may depend on the jurisdiction, dwelling classification, project approval pathway and any relevant variations, exemptions or transition arrangements.
The review may consider step-free access, entrances, thresholds, doors, corridors, internal circulation, sanitary facilities and future grabrail reinforcement.
Architectural plans, levels, sections, door schedules, sanitary layouts and relevant planning or approval information may be needed to confirm the pathway and review the design.
Review is most useful while levels, layouts and structural provisions can still be adjusted without substantial redesign or documentation changes.
Some projects may also require separate adaptable-housing, specialist access, planning or broader NCC advice beyond the Livable Housing Design scope.
The agreed scope may include pathway advice, design review, identification of documentation requirements and assessment support for the relevant livable-housing provisions.
Important: A Livable Housing Design review addresses the agreed residential livability scope. It does not by itself demonstrate complete NCC compliance, AS 1428 compliance or satisfaction of a separate AS 4299 adaptable-housing requirement.
Guidelines and NCC Context
Livable Housing Design in Australia has developed through both voluntary guidance and formal building requirements. The Livable Housing Design Guidelines established Silver, Gold and Platinum levels describing progressively broader residential usability and adaptability outcomes. Although Livable Housing Australia ceased operations in 2025, the guidelines may remain relevant where a planning control, project brief or other requirement specifically nominates a guideline-based outcome.
NCC 2022 introduced separate livable housing provisions for relevant Class 1a dwellings and Class 2 sole-occupancy units. These provisions are located in Part H8 of Volume Two and Part G7 of Volume One. The Deemed-to-Satisfy provisions call up the ABCB Livable Housing Design Standard, which contains technical requirements for matters such as dwelling access, entrances, internal doors and corridors, sanitary facilities, showers and future grabrail reinforcement.
The NCC minimum provisions were adapted from the Silver level of the Livable Housing Design Guidelines. The ABCB also publishes a voluntary Beyond Minimum standard adapted from the former Gold level. These NCC pathways should not be treated as interchangeable with a project that separately requires a Silver, Gold or Platinum guideline review.
The appropriate pathway must therefore be confirmed against the project jurisdiction, building classification, approval requirements and intended assessment outcome. State and territory adoption, variations, concessions and transition arrangements can affect whether the NCC provisions apply and how they should be documented.
The applicable NCC provisions and ABCB Livable Housing Design Standard may provide the prescriptive pathway for relevant Class 1a dwellings and Class 2 sole-occupancy units.
Where a project does not follow the Deemed-to-Satisfy provisions, an appropriately developed and documented Performance Solution may be required within the broader NCC pathway.
A planning control, development condition or project brief may separately nominate a Silver, Gold or Platinum outcome under the Livable Housing Design Guidelines.
A project may voluntarily target requirements beyond the NCC minimum, including the ABCB Beyond Minimum standard or another clearly defined client or planning objective.
Pathway clarification: References to Silver, Gold or Platinum should be checked against the specific project requirement. They should not automatically be interpreted as NCC compliance levels or as confirmation that a formal guideline certification pathway applies.
Jurisdictional Requirements
The National Construction Code includes minimum Livable Housing Design provisions for relevant new Class 1a dwellings and Class 2 sole-occupancy units. However, each state and territory determines how those provisions are adopted, varied and applied within its own building regulatory system.
New South Wales
NSW has not adopted the NCC Livable Housing Design provisions as a general requirement for all new homes and apartments. Livable, universal or adaptable housing requirements may still arise through planning controls, development conditions, housing policies, the project brief or voluntary design objectives.
Western Australia
WA currently excludes the NCC Part H8 Livable Housing Design provisions from general mandatory building application. Project teams should still check applicable planning requirements, local policies, client standards and any project-specific livable-housing or adaptable-housing obligations.
Other Jurisdictions
Victoria, Queensland, the ACT, Tasmania, South Australia and the Northern Territory have introduced the Livable Housing Design provisions within their regulatory pathways. Commencement dates, exemptions, concessions, state variations and transition arrangements may still differ between jurisdictions and NCC editions.
The applicable pathway should be confirmed against the project location, building classification, relevant NCC edition, state or territory variations, planning controls and approval conditions. The absence of a general NCC requirement does not necessarily mean that no project-specific Livable Housing Design requirement applies. Separate adaptable-housing or specialist access requirements should be identified and reviewed under their own relevant pathways.
Project Coordination
A residential project may need several assessments or compliance pathways at the same time. These processes may rely on the same architectural documentation and should be coordinated during design, but each examines a different aspect of the dwelling and produces a different project outcome.
Livable Housing Design focuses on residential usability, applicable livability provisions and supporting design documentation. It does not assess NSW sustainability commitments, thermal shell performance or regulated fixed-appliance and operational energy performance.
BASIX addresses the water, energy and thermal commitments applying to relevant NSW residential projects.
Explore BASIX →NatHERS models the thermal performance of the dwelling shell and produces the relevant residential star rating.
Explore NatHERS →Whole of Home assesses regulated fixed appliances, energy systems and operational residential energy performance.
Explore Whole of Home →Separate assessment outcomes: Coordinating these pathways does not make them interchangeable. Livable Housing Design retains responsibility for dwelling usability, applicable livability requirements and the relevant design-review scope.
Design-Stage Review
Livable Housing Design is easiest to resolve when it is considered early by the design team. Key decisions can affect approach paths, entries, floor levels, thresholds, door openings, corridors, sanitary facilities, services and structural reinforcement. Once these elements are fixed, later changes may become more difficult, more expensive or less successfully integrated into the architecture.
For architects and building designers, early review helps translate the applicable livable-housing provisions into coordinated plans, sections, schedules and details. For builders and developers, it can reduce avoidable redesign and clarify which requirements need to be documented before construction information is finalised. For homeowners, it can support a dwelling that remains practical across changing household needs.
Coordination may also identify requirements that sit outside the Livable Housing Design scope. A project may need separate input from the building certifier, structural engineer, hydraulic consultant or another appropriately qualified specialist. Identifying those boundaries early helps the project team assign responsibility without treating one review as evidence of every related compliance outcome.
Coordinate approach paths, levels, entrances, circulation and sanitary layouts while the design can still be adjusted efficiently.
Clarify applicable requirements and documentation responsibilities before drawings, specifications and construction details are finalised.
Understand which livability features are required or appropriate for the dwelling before important layout decisions are locked in.
Coordinate separate structural, building-certification or other specialist advice where the project requirements extend beyond the Livable Housing Design scope.
Clear responsibility: Early coordination helps establish which consultant reviews each requirement and prevents Livable Housing Design advice from being mistaken for broader NCC or other specialist approval.
Occupant Needs
A dwelling may be used by people with different needs throughout its life. Household composition can change, visitors may have reduced mobility, and an occupant may temporarily find steps, narrow doorways or constrained sanitary spaces difficult to use. Livable Housing Design responds by reducing avoidable barriers in the parts of the home used every day.
Long-term usability does not mean designing every dwelling for every possible future condition. It means addressing the applicable livable-housing requirements and making proportionate design decisions that preserve practical use. Suitable entries, circulation spaces, sanitary layouts and structural provisions can help the dwelling accommodate changing needs without losing its residential character.
The appropriate response should be based on the project brief, dwelling type, jurisdiction and required assessment pathway. Where the project has more specific occupant, planning or approval requirements, an additional specialist review may also need to be coordinated.
The dwelling may need to support children, guests, older relatives or future occupants with different everyday routines.
Entries, thresholds, doorways and sanitary spaces can affect how easily the home can be used as mobility changes over time.
Injury, recovery, pregnancy, prams and visiting family can temporarily change how occupants move through and use a dwelling.
A client brief, planning condition or nominated housing standard may require provisions beyond the general livable-housing pathway.
Frequently Asked Questions
Livable Housing Design addresses residential features that make a dwelling easier to enter, move through and use. Depending on the applicable pathway, it may consider step-free access, entrances, thresholds, door and corridor widths, internal circulation, usable sanitary facilities and structural reinforcement for future grabrails.
No. State and territory adoption of the NCC Livable Housing Design provisions differs. NSW has not adopted them as a general requirement, while Western Australia currently excludes the relevant NCC provisions from general mandatory application. Other jurisdictions have introduced them with their own commencement dates, variations, concessions, exemptions and transition arrangements. Project-specific planning or client requirements may still apply where the NCC provisions do not.
A review may be needed where the project is subject to applicable NCC provisions, planning controls, development conditions, a nominated Livable Housing Design Guidelines level or project-specific requirements. The pathway should be confirmed against the project location, dwelling classification, approval process and intended assessment outcome.
The review may require architectural floor plans, site plans, levels, sections, elevations, door schedules, sanitary layouts and details of entrances and thresholds. Relevant planning conditions, approval requirements, project briefs and any nominated guideline or standard should also be provided where available.
No. Livable Housing Design addresses the residential usability provisions relevant to the dwelling. Those provisions may form part of a broader Deemed-to-Satisfy pathway, but a Livable Housing Design review does not address all residential NCC matters such as energy efficiency, condensation management, structural requirements or general building compliance.
No. AS 1428, the Premises Standards and other specialist access requirements can address matters such as accessible paths of travel, ramps, stairs, sanitary facilities, tactile indicators and signage. These requirements may need a separate specialist access review. A Livable Housing Design review should not be treated as evidence of broader disability-access compliance.
Livable Housing Design focuses on residential usability and the livability provisions applying to the dwelling. Adaptable Housing may involve a separate pathway under AS 4299, including pre-adaptation and post-adaptation layouts, nominated dwelling percentages and specific planning requirements. A project requiring Adaptable Housing may therefore need a distinct assessment scope.
Universal Design is a broad design philosophy that aims to make buildings and environments usable by as many people as practical. It can inform residential design, but it is not itself a Certified Energy assessment or certification product. A project should instead identify the specific provisions, guideline level or assessment pathway it needs to satisfy.
Livable Housing Design requirements most commonly arise for new dwellings or substantial residential projects, where entries, levels, circulation and sanitary facilities can be coordinated during design. Existing homes may also be reviewed voluntarily or as part of renovation planning, although site conditions and the existing construction can limit what can practically be achieved.
These pathways may apply to the same residential project, but they assess different matters. BASIX addresses relevant NSW sustainability commitments, NatHERS models thermal shell performance and Whole of Home assesses regulated fixed-appliance and operational energy performance. Livable Housing Design addresses dwelling usability and applicable livability requirements.
Certified Energy can provide project-specific pathway advice, design-stage review and documentation support for relevant Livable Housing Design requirements. The review can help identify the applicable jurisdictional pathway, assess the proposed dwelling features and clarify where separate building-certification, adaptable-housing or specialist access advice may also be required.
