Welcome to BTA

We are structural designers. 

We work with architects and other professionals to create buildings with elegant, robust and durable structures. Our designs use the best materials whether traditional or modern, and we strive for economy and sustainability in our projects.

We are also involved with conservation and repair of historic structures. All old buildings were modern once and we apply the lessons of the past in the designs of the future.

We have a strong commitment to good design. We like to be involved early in a project so that the architectural and structural design can develop together.

We relish a challenge.

In this website we have highlighted a selection of interesting projects; please contact us if you would like to find out more.


Some of our recent projects

Church Walk


Church Walk provides 4 great homes within what seemed an unpromising urban site. The design sought to make memorable housing at high density whilst being neighbourly.

Oatlands Close


We worked with Soup Architects on renovating and extending an existing 4-bedroom house on a long north/south axis site in Surrey. The existing house had a very poor connection to a fantastic rear garden.

On a designated site of ‘Outstanding Natural Beauty’, Broombank is set into sloped banks and accessed via a single-track lane that arrives into a sunken entrance courtyard, offering glimpses of the views beyond.
