Heritage significance does not automatically remove the need to consider disability access. In Australia, the practical task is to identify which access obligations apply, understand which heritage elements are genuinely significant, and develop an upgrade strategy that improves equitable use without causing avoidable harm to the place.
For owners, architects, councils, facility managers and building surveyors, the best outcomes usually come from early coordination between the access consultant, heritage adviser, designer and approval authority. Waiting until a permit application or tender stage can turn manageable design choices into expensive conflicts.
Why heritage accessibility projects need a different process
Existing heritage buildings can contain narrow entrances, steps, steep changes in level, heavy doors, small lifts, constrained circulation, delicate finishes and significant façades. These conditions do not make access improvement impossible, but they do mean that a standard detail may not be the right starting point.
The first question should not be “Can the building be exempt?” It should be “What access outcome is required, what parts of the place are significant, and which design options can achieve the outcome with the least heritage impact?” That approach creates a clearer evidence trail for design decisions and approvals.
The Australian regulatory context
The Disability Discrimination Act 1992 addresses discrimination in access to premises and services. The Australian Human Rights Commission notes that existing places may need to be modified to be accessible, except where doing so would involve unjustifiable hardship.
The Disability (Access to Premises — Buildings) Standards 2010 provide a framework for certain building work and contain provisions relevant to existing buildings, affected parts and unjustifiable hardship. The applicable outcome depends on the proposed work, the building, the people involved and the approval pathway.
The National Construction Code also regulates access for people with disability in relevant Class 2 to 9 buildings. The ABCB’s Upgrading existing buildings handbook explains that new work generally needs to comply and that some projects can trigger work to an “affected part” connecting the principal pedestrian entrance to the area of new work.
Heritage controls operate alongside these access requirements. In Victoria, a place may be subject to a Heritage Overlay, inclusion on the Victorian Heritage Register, local planning controls or other approvals. The project team should confirm the heritage status and approval authority rather than relying on appearance or age alone.
Heritage listing is not a blanket access exemption
A heritage listing can be highly relevant to the feasibility and impact of an access proposal, but it does not mean the project can ignore access. The Premises Standards include heritage features among the matters that may be considered when assessing unjustifiable hardship. That assessment is specific to the circumstances and considers all relevant benefits, costs, difficulties and impacts.
It is therefore risky to write “heritage exemption” on a drawing without a documented basis. A robust process tests reasonable alternatives first. It should identify which element is significant, explain how a proposed change would affect it, compare less damaging options, and record the access benefit each option provides.
Start with two coordinated investigations
1. Access audit
An onsite access audit should trace the complete user journey, not just the front step. Depending on the use, it may cover:
- arrival from the site boundary and accessible parking;
- the principal and alternative entrances;
- doorways, thresholds and door controls;
- internal paths, ramps, stairs and lifts;
- reception and service points;
- sanitary facilities and change facilities;
- signage, wayfinding, lighting and luminance contrast;
- hearing augmentation and other communication features;
- access to the services and experiences offered in the building.
2. Heritage significance assessment
The heritage adviser should identify significant fabric, spaces, views, forms and uses. Not every component of an old building has the same value. Later additions, altered openings or less significant service areas may provide opportunities for access work with lower heritage impact.
These two investigations should be mapped together. That allows the team to see where a major access barrier coincides with highly significant fabric, and where a practical route may be available through a less sensitive area.
Develop options before selecting a solution
Good heritage access design usually compares several options rather than defending the first concept. Potential strategies may include:
- regrading external surfaces where levels permit;
- using a secondary entrance only when it can provide a dignified and equivalent arrival experience;
- installing a sensitively located ramp or platform lift;
- reworking a later addition instead of significant original fabric;
- automating a heavy door while retaining its appearance;
- adjusting thresholds with reversible interventions;
- relocating a public service to an accessible level;
- providing an accessible sanitary facility in a compatible location;
- using a documented Performance Solution where appropriate.
A secondary entrance should not automatically be treated as acceptable simply because it avoids the main façade. Review opening hours, signage, security, weather protection, staff assistance, travel distance and whether a visitor receives a comparable experience.
When can a Performance Solution help?
A Performance Solution can be useful where a Deemed-to-Satisfy pathway cannot be followed because of a physical or heritage constraint, but an alternative design may still satisfy the relevant NCC Performance Requirements.
The process requires clear performance criteria, an agreed assessment method and evidence that the proposed design achieves the required level of performance. It is not a general waiver and should not be used to justify an inaccessible outcome without analysis.
Engage the building surveyor and relevant specialists early. Depending on the issue, evidence may include drawings, measurements, access modelling, risk analysis, operational controls, product information and consultation with affected stakeholders.
What evidence supports an unjustifiable-hardship assessment?
Unjustifiable hardship is a legal concept, not a casual description of inconvenience or cost. The Premises Standards require consideration of all relevant circumstances. Heritage significance can be one factor, but it should be supported by specific evidence.
A project file may need to include:
- the heritage listing, statement of significance and relevant permit advice;
- an access audit identifying the barrier and affected users;
- drawings and photographs of existing conditions;
- options considered and reasons for rejection;
- heritage-impact advice for each feasible option;
- cost information proportionate to the decision;
- benefits of improved access to occupants and the community;
- any alternative measures and their limitations;
- records of consultation and decisions.
Project teams should obtain legal or project-specific approval advice where required. An access consultant can provide technical access analysis, but cannot unilaterally declare that unjustifiable hardship exists.
Common mistakes in heritage access projects
- Assuming age equals exemption. Confirm the actual regulatory and heritage status.
- Designing the ramp first. Audit the complete journey and compare options.
- Ignoring the service outcome. Reaching the doorway is not enough if key facilities remain unavailable.
- Using an undignified back entrance. Test equivalence, safety and independent use.
- Leaving consultants to work separately. Access, heritage and approval advice should inform the same option analysis.
- Relying on operational assistance alone. Staff procedures can support access but may not replace a reasonable built solution.
- Failing to inspect construction. Small changes to gradients, thresholds, hardware and clearances can alter the outcome.
A practical project sequence
- Confirm building classification, project scope, heritage status and approval authorities.
- Complete the access audit and heritage significance review.
- Agree on the required access outcomes and assessment criteria.
- Develop and compare several design options.
- Consult the building surveyor, heritage adviser and relevant authority early.
- Document any Performance Solution or hardship assessment with project-specific evidence.
- Coordinate detailed design, products and construction tolerances.
- Inspect the completed work and record remaining operational responsibilities.
When to engage an access consultant
Engage an access consultant before the design team fixes the entry, circulation core or tenancy layout. Early advice is especially valuable before purchasing or leasing a heritage property, changing a building’s use, lodging a heritage permit, or setting a refurbishment budget.
ASN can combine a desktop access review with onsite investigation and targeted design advice. For a heritage building in Melbourne, Victoria or elsewhere in Australia, contact ASN to discuss the site, proposed works and approval stage.
