Good design makes places better.  Sometime this means a new building, sometimes it's just a change of colour or texture in a space.  Good design always means a careful and sensitive understanding of the needs of the client.  Each design is tailored to those needs, finding a dialogue between the existing building and the proposals, resulting in beautiful new spaces inside and out.

Every project is unique and is approached without a stylistic agenda - whether a design is traditional or modern it should always have a positive relationship with its surroundings.  Successful projects are always the result of good communication and collaboration between the client, the designer and the builder.


We are a small two-person practice formed in early 2009 specialising in residential projects.  If you need to alter, extend or replace your home then we can help.  We also work on other building types, and have experience with projects in education, healthcare, community buildings, gallery spaces and office refurbishments.  

We work in London, and the south of England, occasionally travelling further for the right projects and clients.


Stuart graduated from the Welsh School of Architecture with 1st class honours in 2004, qualified as an Architect in 2008, and is registered with the Architect's Registration Board.  Before forming ASH he worked for a number of award winning practices in London and across the UK, gaining experience in all types and scales of projects, from residential extensions through to high rise commercial office blocks.  He also worked in specialist conservation practices in Bath and Devon, where more sensitive design is essential in order to work with conservation areas, listed buildings and heritage projects.

Alongside his architectural practice Stuart works as a Studio Tutor at the Welsh School of Architecture, and as a guest critic at architecture schools across the UK.

Stuart is also part of ad:HOC, a collaborative group of architects aiming to forge closer links between architectural theory, teaching, and practice.
