What services does giantA Pty Ltd provide?

giantA Pty Ltd is a Sydney architecture firm providing architectural design, drafting services, and energy assessment (BASIX and NatHERS). We specialise in Development Applications (DA), Complying Development Certificates (CDC), Construction Certificates, Building Information Certificates, and Section 4.55 and 4.56 modifications across NSW.

Where is giantA Pty Ltd located?

giantA Pty Ltd is based in Parramatta CBD, Western Sydney, and serves clients across the Sydney metropolitan area and wider New South Wales. You can reach us on +61 488 880 787 or at info@giantA.com.au.

Does giantA handle Development Application (DA) preparation in NSW?

Yes. We specialise in preparing Development Applications for residential projects across NSW, including the Statement of Environmental Effects and the architectural drawings councils require, with each output referenced to the relevant EP&A Act, LEP and DCP planning controls.

What approval pathways are covered in the Design, Approvals & Compliance Hub?

The hub covers all NSW approval pathways: exempt development, Complying Development Certificates (CDC) issued by private certifiers, council Development Applications (DA), Construction Certificates (CC), Building Information Certificates (BIC), and Section 4.55 and 4.56 modifications. Resources span all building classes under the National Construction Code.

Should I use a private certifier or lodge through my local council?

It depends on your project type and complexity. Private certifiers can issue CDCs within 10 days for straightforward, low-impact projects. Council DA assessment is required for larger builds, heritage properties, or works that fall outside CDC standards. Our DA and CDC guides help you choose the right pathway for your timeline and budget.

Are the floor plans and tools in the hub really free to use?

Yes. The floor plan library, cost estimating tools, DA and CDC checklists, and planning portal links are all free resources giantA provides to help NSW property owners plan and prepare their building applications. Professional design and drafting services are quoted separately based on project scope.

Design, Approvals & Compliance Hub

Designing and building in NSW involves far more than a council approval — and this hub is built to support every stage of that journey. Here you'll find free floor plan references, construction cost estimating tools, DA & CDC checklists, council DCP lodgement guides, and drawing package standards used on real projects across Sydney and regional NSW. We cover every approval pathway — exempt development, Complying Development Certificates issued by private certifiers, council Development Applications, Construction Certificates, Building Information Certificates, and Section 4.55 & 4.56 modifications — across all building classes under the National Construction Code, from granny flats and duplexes to commercial, industrial and mixed-use developments. New guides, tools and industry updates are added continuously as regulations, fees and planning policies evolve.
