Studio

Trewhela Williams is an award-winning architecture and bespoke interiors practice based in Southwest London. Established in 2016 by Perran Trewhela and Joseph Williams, the practice works on residential, cultural and ecclesiastical projects across the UK through from concept to construction.

Our projects are characterised by their conceptual clarity, thoughtful approach to materiality and their detailed rigour. Central to this is our passion for working with natural materials and exploring the means in which they can be shaped and finished to best harness their intrinsic qualities. This attention to craftsmanship has been recognised by the Brick Development Association who featured the brickwork detailing of our debut project ‘Sinter House’.

We strive to shape poetic interiors that are practical in nature, 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.
