What Garnett Architecture does
Garnett Architecture LLP is a London-based architectural practice founded in the early 1990s by Christian Garnett and operating under a limited liability partnership structure. The firm is headquartered at Studio 309, The Print Rooms, 164-180 Union Street, London SE1 0LH, and employs 18-20 staff across Partner, Associate Partner, Associate, Senior Architect, BIM Architect, Project Architect, Architects, Interior Design Consultant, and Architectural Assistant roles. A wholly-owned subsidiary, Garnett Design Management Ltd, operates from a neighbouring studio in the same building and provides technical design coordination and CDM Principal Designer services as an adjacent consulting line.
The practice delivers a broad range of consultancy services, with core offerings in architecture and interior design, town planning, and sustainability, alongside specialist capabilities in adaptive re-use, workplace design, residential architecture, retail design, and heritage/conservation services. Underlying methodologies follow the RIBA Plan of Work, with BIM processes managed in-house. The firm's distinctive technical positioning centers on heritage assessment, conservation, and the adaptive re-use of listed buildings and assets within London's Conservation Areas, frequently navigating planning with statutory consultees such as Historic England and the Greater London Authority.
Garnett Architecture operates on a project-by-project, fee-for-service basis serving enterprise clients exclusively: major London real estate investors and asset managers (Royal London Asset Management, Shaftesbury Capital, BlackRock, Legal & General, Aberdeen Standard Investments, Capco, Astrea Asset Management), Great Estate managers (Portman Estate, Bedford Estates, Cadogan Estate, Berners-Allsopp Estate), private high-net-worth residential clients, hospitality operators (W.RE, x+why), and retailers. Pricing is negotiated per project—typically structured as a percentage of construction cost or fixed fee per RIBA work stage—with construction contract values on disclosed projects ranging from approximately £4.5M to £10.5M. The firm reports over 60% repeat business and client relationships exceeding 20 years, indicating a relationship-driven, referral-led go-to-market motion with no disclosed external funding, parent company, or digital distribution channels.
