Common Questions

Frequently Asked Questions

A Change of Use occurs when a building is repurposed for a different occupancy class — for example, converting a warehouse to an office, or a retail shop to a restaurant. It typically triggers a requirement to upgrade fire safety systems, DDA amenities, and structural elements to meet the current NCC (National Construction Code).

Common upgrades include fire sprinkler and detection systems, emergency lighting and exit signage, DDA-compliant accessible amenities, acoustic treatments, ventilation upgrades, and structural reinforcement. We assess all requirements upfront to give you a complete picture.

If you are planning to use a building for a purpose different from its current planning permit classification, a Change of Use permit from council and a building permit for the associated works will be required. We can advise you during an initial consultation.

Yes. We coordinate with planning consultants, building surveyors, and the relevant authorities to manage the full approval process from start to occupancy certificate — keeping you informed throughout.

Timelines depend on the extent of compliance works, the speed of authority approvals, and the occupancy class involved. Most projects range from 3–9 months. We'll provide a realistic program at your initial consultation.
