Simpson Studio Architects

Based in London, Simpson Studio Architects crafts expressive interior spaces through custom joinery, bold material juxtapositions, and inventive spatial insertions like concealed passages and textured mini-pavilions. The portfolio offers a strong reference when resolving heavy stone kitchen islands with contrasting cabinetry or designing bespoke, scale-clad play pods for domestic and educational settings.
