What architectural services do we provide?
We provide end-to-end architectural services for all classes of buildings under the National Construction Code:
- Concept Design & Feasibility: Site analysis, yield studies, and concept development tailored to your vision.

How do we ensure BASIX & NatHERS compliance?
Every residential project in NSW requires a BASIX certificate and, for most dwellings, a NatHERS 7-star energy rating. Our in-house energy raters prepare both simultaneously, ensuring your DA or CDC lodgement is complete on day one.
We stay current with NCC 2025 changes that tighten thermal performance requirements. Whether your project is a granny flat, duplex, townhouse, or custom home, we model energy performance early in the design phase — not as an afterthought — so compliance is built into the architecture, not bolted on.
What is our architectural outsourcing service?
For builders, developers, and interstate or international design studios, giantA offers architectural outsourcing and white-label documentation support. We provide capacity overflow drafting, DA documentation packages, and BASIX compliance assessments on a fixed-fee basis — integrating seamlessly with your team through our ERP and BIM-enabled workflow.
Whether you need a single DA package prepared while your in-house team is at capacity, or ongoing documentation support for a multi-site development pipeline, our outsourcing service delivers the precision and compliance rigor of a Sydney-based architectural firm without the overhead of expanding your permanent team. Explore our drafting services, cost estimating, and BIM capabilities.
How does our project process work?
Every project at giantA Pty Ltd follows a structured, client-centred process aligned with Australian Institute of Architects (AIA) best practice and NCC standards:
- Concept Design: We translate your brief into innovative architectural models and ideas.
- Design Development: Refining outcomes with a focus on sustainability, energy efficiency, and buildability.
- Planning & Applications: Meeting BASIX requirements, preparing DA/CDC packages, and lodging via the NSW Planning Portal.
- Construction Documentation: Complete architectural drawing sets and technical specifications for your builder.
- Contract Administration: Supporting you through builder selection, contract negotiation, and construction oversight.
This end-to-end process ensures projects are delivered with integrity, accuracy, and creativity. See our design process page and DA/CDC checklist for details.
Who do we collaborate with?
We partner with registered architects, structural engineers, landscape architects, builders, and developers across NSW. Our collaborative ecosystem leverages ERP systems and BIM technology for seamless project management — enabling us to deliver consistent outcomes whether your project is a single dwelling in Parramatta or a multi-unit development in Western Sydney's growth corridors.
Exchange of expertise between our Parramatta and Kingswood studios is standard practice. A single project may draw on BASIX specialists, drafting leads, and design principals working together as one team — ensuring you benefit from our collective knowledge base. Meet our partners and our team.
Why choose giantA for sustainable design?
Sustainability is not a compliance checkbox — it is a design philosophy. We integrate energy audits, passive solar principles, and material efficiency into every project, targeting 7-star NatHERS ratings and beyond.
As proud members of BDAA, AIA, and HERA, we invest in continuous professional development to stay ahead of evolving standards. From small green initiatives to major sustainable developments, giantA demonstrates that architecture can embody wellness, community value, and environmental responsibility simultaneously.
