Simpson Studio is an award-winning architecture and interior design practice, with studios in Edinburgh and London.

Founded in 2013, we deliver architecture, interiors and bespoke cabinetry as one considered process, from first concept through to completion. Our work spans private homes, hospitality and commercial spaces across the UK, shaped by clarity of thinking, responsibility to context and a commitment to lasting quality.

Workshop with elm, oak and Douglas fir timber, Makita tools, a work bench with wooden and marble side table being made.

Where many studios step away once drawings are signed off, we remain closely involved throughout delivery.

This continuity ensures design intent is protected, decisions are resolved with care, and every detail feels purposeful and resolved.

Working across architecture, interiors and cabinet making allows us to design holistically, considering structure, space and material together, rather than as separate layers.

Mr and Mrs S Buchanan

“Simpson Studio provided an impeccable, friendly and extremely professional service to us for our house extension design and planning. We gave them our overall vision and wish list and they turned this into an incredible and innovative design, that exceeded our expectations. During the design phase, they kept coming back to us with ideas and gave us ample opportunity to ask questions and to provide input. This meant that there was a feeling of shared ownership of the design, which was wonderful. Simpson Studio proved themselves to be approachable, collaborative and open with their clients, as well as experts in architectural design. They have also taken care of the planning process for us which is a great weight off our minds. We would heartily recommend Simpson Studio as architects to anyone in the UK.”
