Stonewood Design

What Stonewood Design does

Stonewood Design is a private UK architectural practice headquartered in a Grade II Listed 17th-century malthouse called 'Delicious House' at 67 High Street, Corsham, Wiltshire. Founded in 2010 and operating as Stonewood Design Ltd., the firm employs 18 staff led by three Directors (Nicola du Pisanie, Adam Chambers, Matt Vaudin) with an additional Associate Director and a team of architects, senior associates, and Part II Architectural Assistants. The practice delivers full architectural services — from concept and planning through technical design and on-site delivery — across five end-markets: cultural and heritage buildings, residential, educational, commercial, and heritage/conservation work.

Its core technical differentiator is a sustainability-led, context-driven design methodology codified in the proprietary Stonewood Design Sustainability Principles framework (reviewed at each RIBA Project Stage) and the 'Mean, Lean, Green' energy hierarchy. The practice holds RIBA Chartered Practice status, ISO 9001 and ISO 14001 accreditations, is pursuing B-Corp Certification, and is a signatory of Architects' Declare and the RIBA 2030 Climate Challenge. Domain expertise spans Passivhaus design, heritage building adaptation with moisture and thermal performance management, and contemporary use of low-carbon materials including rammed earth, thatch, oak shingles, wattle and daub, and hemp. Award output includes three RIBA National Awards (2015, 2019, 2021), six regional RIBA South West / Wessex Awards, RIBA South West Building of the Year 2025, Royal Fine Art Commission Trust Grand Winner 2025 and Civic Trust Award 2026.

The firm operates a professional services revenue model, earning fees on a project-by-project basis through direct client engagement, professional referrals and repeat commissions. The go-to-market is sales-led and relationship-driven, with no public pricing and no digital product distribution. Geographic focus is South West England for commercial work, with a small footprint of pro-bono and exploratory projects in South Africa, Namibia, Uganda and Southern Europe. Notable clients include the Woodland Trust, Kingswood Preparatory School, Millfield School, the Story of Emily Museum, the Story of Gardening Museum, the Roman Villa Museum, Dyson Farming and Real World Studios. The firm is privately held with no external investment, parent company, or M&A activity disclosed.
