Frequently Asked Questions
What types of commercial projects does giantA design?
We design retail fit-outs, office interiors, mixed-use buildings, childcare centres, medical suites and small-scale industrial units. Our Registered Design Practitioner status allows us to sign off on Class 5 (office), Class 6 (retail) and Class 9c (aged care) buildings under the NSW Design and Building Practitioners Scheme.
Do I need an architect for a commercial fit-out in NSW?
For most commercial fit-outs under $500,000 construction cost, a building designer or architect is recommended but not legally required. For Class 2, 3 and 9c buildings (apartments, hotels, aged care), a Registered Design Practitioner is mandatory. We advise based on your building class and project value.
How much does commercial architecture cost in Sydney?
Commercial architectural fees typically range from 5% to 12% of construction cost, depending on complexity. A $300,000 retail fit-out might cost $15,000–$30,000 in design and documentation. A $2 million mixed-use development could cost $100,000–$200,000+ for full architectural services.
What approvals do I need for a commercial project?
Most commercial work requires a Development Application (DA) with council, unless it qualifies as exempt or complying development under the relevant SEPP. Construction Certificate (CC) or Complying Development Certificate (CDC) follows. Some projects also need fire safety certification, disability access reports and hydraulic engineering.
Can giantA handle DA lodgement for commercial projects?
Yes. We prepare the full DA package including architectural plans, Statement of Environmental Effects, shadow diagrams, waste management plans, and coordinate specialist consultants (structural, hydraulic, fire). We lodge via the NSW Planning Portal and manage RFI responses.
How long does commercial DA approval take in Sydney?
Small-scale commercial (retail fit-out, minor alterations): 6–12 weeks. Medium-scale (new commercial building, mixed-use): 4–9 months. Large-scale or state-significant: 12+ months. Pre-lodgement meetings with council reduce assessment time significantly.
