What Stride Treglown does

Stride Treglown is a privately-held UK architectural and multi-disciplinary design practice founded in 1953, operating 9 studios across England and Wales (Bath, Birmingham, Bristol, Cardiff, London, Manchester, Plymouth, Truro, Winchester) with 300+ specialists. The firm delivers 12 core services spanning architecture, interior design, landscape architecture, masterplanning and urban design, town planning, BIM and digital design, graphic design, historic buildings conservation, sustainability, design for manufacture, principal designer, and RIBA client adviser, organised around 15 client sectors including education, healthcare, residential, commercial, civic, infrastructure, and technology & innovation.

The practice's go-to-market combines direct enterprise sales (appointment via Service and Sector heads) with public sector procurement through three frameworks: NHS Shared Business Services (Aug 2023–Aug 2027), Procure Partnerships, and SEWTAPS (through April 2025 with two 12-month extensions). Revenue is generated on a professional services fee basis; pricing is quote-based and not publicly disclosed. Frameworks provide pre-agreed competitive rates and compliant procurement routes for public sector clients including NHS bodies, universities, local authorities, and housing associations.

Stride Treglown is the first large UK architectural practice to hold B Corp certification (2021) and transitioned to full employee ownership in 2025, reflecting its values-led positioning. Differentiated platforms include the Inhabitant post-occupancy evaluation programme and the Engage client feedback programme (run with insight6, producing an NPS of 59 and 84% five-year key client retention). Verified outcomes include a 12.3% Biodiversity Net Gain at New Fosseway and the 926-bed Passivhaus student village planning approval at University of Bath.
