What Design 5 Architects does

Design 5 Architects is an Australian heritage conservation and adaptive reuse architecture practice headquartered in Chippendale, NSW, operating since 1992 with a team of approximately 15 staff. The firm specializes in Conservation Management Planning, heritage advisory services, and the architectural delivery of conservation, adaptive reuse, and new-work projects within heritage contexts. Its underlying methodology combines rigorous building-fabric research and analysis with contemporary design capability, producing what the practice describes as 'architecture that speaks truthfully of its time.' Notable proprietary content includes published research on traditional Australian joinery (the 'Traditional Joinery Sydney Houses 1810-1915' reference work) and Conservation Management Plans for significant sites including the Sydney Opera House, White Bay Power Station, and Cockatoo Island.

The firm's client base is concentrated in government heritage bodies (Sydney Opera House Trust, NSW Public Works, Transport for NSW, Placemaking NSW), cultural institutions (Australian Museum, Tasmanian Museum and Art Gallery, Taronga Conservation Society), and select property developers and private owners. Service delivery is structured around direct commission and competitive tender, with the firm frequently operating in collaborative project teams alongside peer architects such as ARM Architecture, fjcstudio, Peter Stutchbury Architecture, ASPECT Studios, Bates Smart, and SJB.

Revenue is generated through professional services fees on a project-by-project basis, with pricing determined by scope, complexity, and duration. The firm holds Nominated Architect registrations in NSW and Tasmania, M.ICOMOS credentials across multiple staff, and active roles with the Heritage Council of NSW and Australia ICOMOS. It is independently owned and operated by principals Alan Croker and Matthew Byrnes, with no disclosed external investment, parent company, or subsidiaries. The practice has accumulated a substantial award portfolio including UNESCO Asia-Pacific (2014), Docomomo International (2021), and multiple AIA National and state-level recognitions through 2026.
