Alex Tart Architects

What Alex Tart Architects does

Alex Tart Architects is a Chartered RIBA architectural practice founded in 2013 and structured as a UK private limited company. The firm is headquartered in Putney, London, with a second office in Bath, and operates with a boutique team of 1-10 employees under the direction of founder Alex Tart. It provides bespoke residential architecture services — both classical and contemporary — to affluent private clients across Central London, South West England, Yorkshire, and other UK country locations, targeting the Prime and Super Prime housing market.

The practice delivers end-to-end services spanning all RIBA work stages: concept design and project planning, planning and listed building consents (with a reported 97% success rate), interior design, project management, construction drawings, and sustainable design. Its technology stack is conventional — AutoCAD, SketchUp, Photoshop, Word, and Excel — with 3D modeling used to enable remote client presentations. There is no disclosed AI/ML capability or proprietary technology platform. The firm distinguishes itself through specialist expertise in heritage and conservation-area work, including Grade I/II listed buildings and basement excavations.

Revenue is generated on a project-based professional-fee model, with fees determined by scope, complexity, and property value rather than through publicly disclosed pricing tiers. The go-to-market relies on portfolio presentation via the firm website, sustained editorial coverage in prestige publications (Architectural Digest, House & Garden, Grand Designs, The Times, Porter Magazine, RIBA Journal), and repeat professional referrals from a long-standing partner ecosystem that includes Qubed, Cameron Jones Planning, Davies Maguire, Regency Grove, Slender Winter, and Mazzullo + Russell. Client confidentiality norms in HNW residential work mean that no individual clients are publicly named, and no revenue figures have been disclosed.
