Studio
Trewhela Williams is an award-winning architecture and design practice based in Southwest London. Established in 2023 by Perran Trewhela and Joseph Williams, the practice works across a number of sectors with a particular specialism in one of a kind private houses.
Our projects are characterised by their conceptual clarity, thoughtful approach to materiality and their detailed rigour. This attention to craftsmanship has been recognised by the Brick Development Association who featured the brickwork detailing of our debut project ‘Sinter House’.
We aspire to shape poetic interiors that are human-centric in detail and enrich the daily lives of their users. Our sequel project ‘Elizabeth Mews’ won the 'Transformation Prize' in the NLA Don't Move Improve! Awards 2023, which celebrates the best homes being redesigned in London.
An expanded portfolio is avaialble upon request.
