Heritage Constraints
Providing compliant access within heritage buildings requires careful balancing of accessibility requirements with the preservation of heritage significance.
Heritage constraints often limit the use of Deemed-to-Satisfy provisions. This situation requires a considered project-specific approach. Such an approach is necessary to achieve appropriate and compliant outcomes.
Balancing Access and Heritage Requirements
Heritage buildings form a significant part of the existing built environment. Improving access can be challenging. Changes may impact the original fabric or character of the building.
In many cases, achieving compliance requires balancing:
- preservation of heritage significance
- accessibility and usability for occupants
- regulatory and planning requirements
This often involves collaboration between access consultants, heritage consultants and the broader design team.
These projects often require negotiation with approval authorities to achieve an acceptable balance between access and heritage outcomes.
When Heritage Constraints Apply
Heritage-related access issues commonly arise:
- in existing buildings undergoing upgrade or change of use
- where heritage fabric cannot be altered or removed
- where existing footing systems or paving cannot be excavated
- where spatial constraints limit circulation or clearances
- where vertical access (e.g. lifts) is difficult to achieve
- where external appearance or streetscape must be preserved
Typical Challenges
Common challenges include:
- achieving compliant paths of travel within constrained layouts
- upgrading entry points without impacting heritage façades
- providing vertical access in multi-level buildings
- integrating accessible sanitary facilities into existing structures
- maintaining required clearances without significant alteration
- Incorrect or poorly considered interventions can impact heritage significance or result in non-compliance.
These challenges often require alternative approaches to achieve compliance.
Performance-Based Solutions
Where Deemed-to-Satisfy provisions cannot be achieved, Performance Solutions are typically required. These solutions:
- respond to the specific constraints of the building
- consider both access and heritage requirements
- provide a structured, evidence-based pathway to demonstrate compliance
Performance-based approaches are commonly used in heritage projects where prescriptive compliance is not feasible.
Key Considerations
When assessing heritage and access, key factors include:
- significance and sensitivity of heritage elements
- feasibility of physical alterations
- impact of proposed works on heritage value
- alternative means of providing access
- input from heritage consultants and authorities
Solutions are often required to be reversible, sympathetic and minimally intrusive where possible.
Our Approach
Access Central works closely with project teams and heritage consultants to develop practical and compliant access strategies. Our approach focuses on:
- understanding heritage constraints and project objectives
- identifying compliant and feasible pathways
- developing Performance Solutions where required
- providing clear, defensible advice to support approval
Conclusion
Heritage and access require a thoughtful approach to achieve outcomes that are compliant and respectful of the building’s significance. With appropriate assessment, practical and defensible solutions can be achieved.
