What Gresley Abas does

Gresley Abas is a Perth-headquartered, private architectural practice founded in 2004 by Philip Gresley and Ahmad Abas, delivering design services across community facilities, residential, educational, bridge/infrastructure, and urban master planning sectors. The firm operates across five interconnected service lines — Community, Living (Residential), Learning, Future Visioning (urban design and master planning), and Bridges — with a Sustainable Design module embedded across all work, evidenced by a B Corp certification (2023), Green Star Accredited Professional leadership, and a public commitment to becoming a Regenerative design practice by 2030. Its go-to-market is sales-led and procurement-driven: the firm acquires work through competitive tendering, design competitions, and direct commissions, and holds appointed supplier status under the WALGA Preferred Supplier Program (PSP003) for WA local government. Revenue is generated via project-based professional fees, with multi-year contract cadence typical of civic and government commissions across Western Australia, Victoria, and Queensland. Notable clients include state and local government departments, educational institutions (Curtin University, TAFE), and private developers such as Modus Developments and Frasers Property Group. The firm differentiates through deep First Nations engagement (Australian Indigenous Design Charter adoption), social and affordable housing expertise (Common Ground projects, Housing First Advisory Group participation), and award-winning civic infrastructure (Mandurah Traffic Bridge, Koombana Bay Pedestrian Bridge, Wunggurrwil Dhurrung Aboriginal Community Centre). Current leadership comprises Directors Tanya Jones (Delivery, 30 years' experience, AIA Fellow) and Jonathan Lake (Design, 28 years, Green Star Accredited), supported by approximately 14 staff based at Level 5, 56 William Street, Perth.
