What Carter Williamson Architects does

Carter Williamson Architects is a Sydney-based architecture and urban design studio founded in 2004, operating from a single studio on Wangal Country in Summer Hill, NSW. The firm is co-owned by principals Shaun Carter (founder, former AIA NSW President) and Ben Peake (co-owner since December 2023, 2023 National Emerging Architect Prize winner), with three design directors (Julie Niass, Nuala Collins, Julia English). The studio delivers full architectural services across residential (new homes, alterations and additions, heritage restorations, multi-residential), commercial and mixed-use, public/civic, educational, heritage conservation, interior design, and urban design/masterplanning. Notable commissions include the Hinchcliff House wool store conservation for AMP Capital's Quay Quarter Lanes, the Concord Central $2.2 billion masterplan for Billbergia Group, the Woodcroft Neighbourhood Centre for Blacktown City Council, the Burwood Girls High School STEM and Performance Space, and a suite of low-rise housing designs commissioned by the NSW Government Architect for the state's Housing Pattern Book at 7-Star NatHERS ratings. The firm also developed GRID, a prefabricated flat-pack emergency shelter for climate-disaster response.

The firm's core technology is professional architectural design services — concept, documentation, and project delivery — supported by a portfolio of 25+ industry awards (Walter Burley Griffin Award, multiple NSW and National Architecture Awards, Good Design Gold, IDEA Awards) and recurring design competition success. Differentiated capabilities include heritage conservation expertise, "Connecting with Country" First Nations design partnerships (with Bangawarra, garigarra, and Artefact Heritage), and sustainability positioning anchored in 7-Star NatHERS outcomes.

The business model is professional services: fees are generated through commissioned architectural projects, design competitions, and government tenders, with pricing quote-based and varying by project scope. Distribution is direct-to-client, with no public pricing and no intermediary sales channels. The studio is privately held, with no external institutional investment or parent company, and operates as a partnership led by its two principals.
