Simon Brown Architects

What Simon Brown Architects does

Simon Brown Architects is a RIBA Chartered architectural practice headquartered on Eel Pie Island in Twickenham, London, founded in 2009 by Simon Brown. The firm specializes in designing and delivering high-quality private homes, residential and mixed-use schemes, and commercial projects, balancing design excellence with commercial viability and environmental responsibility. Its client base comprises two primary segments: high-net-worth private clients seeking bespoke residential architecture (one-off houses, extensions, renovations, listed building conservation) and property developers commissioning multi-unit residential, mixed-use, and commercial fit-out projects across London, Surrey, and Essex.

The practice operates against the four-stage RIBA Plan of Work - Feasibility & Concept Design, Developed Design & Planning, Technical Design & Contractor Tender, and Construction on Site to Handover - drawing on standard architectural tools including CAD drawings and 3D modelling. Differentiated capability areas include navigation of complex UK planning environments (conservation areas, listed buildings, Green Belt sites) and BREEAM 'Excellent' / zero-carbon project delivery. Notable built work includes Eaton Park (Cobham), Arts House (Esher), Henley Town Centre (55-home mixed-use), The Courtyard Apartments (23 zero-carbon apartments), and Luke Street office refurbishment.

Revenue is generated through professional services fees structured as fixed-fee engagements with stage-based breakdown, on multi-year contract cadences, with no public revenue or pricing disclosure. The go-to-market is direct client engagement with no intermediary channels, supported by an organic digital presence across Instagram, Pinterest, X/Twitter and a categorized website portfolio. The firm is founder-owned and privately held, with Simon Brown concurrently having co-founded Hale Brown Architects in 2013. Headcount is reported at 1-10 employees, and no external funding, M&A activity, or parent company relationships are disclosed.
