Structural Design

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.

La Zagaletta

A beautiful and dramatic new house in Spain by Thomas de Cruz Architects. We prepared a structural scheme for the reinforced concrete frame in conjunction with the architects. This was then detailed and implemented locally.

Old Dairy, Wandsworth
Interesting House and former dairy in South London

Enlargement and remodelling of an interesting house and former dairy in South London, creating a wonderful modern house. We provided a full structural design service for the works which included removal of much of the internal structure of the building, and a new steel frame including a dramatic rear extension.

Extension to Listed House in Berkshire
Extension to Listed House in Berkshire

A dramatic and contrasting glazed kitchen extension to a beautiful mellow brick village house. The free standing steel framed structure is touching but independent of the house, and designed to have minimal impact on the fabric of the listed building while creating a truly modern space for the kitchen. We designed the structure for the extension and its connection to the house.

New House Near Cambridge
New House Near Cambridge

A new contemporary house near Cambridge by David Mikhail Architects. The structure up to first floor level is of masonry and concrete to give thermal mass and stiffness to the floors. Above first floor the structure is timber framed, cantilevered and offset from the structure below. The relationship of glazing and structure was very carefully detailed to give clean lines and to meet all thermal heat loss requirements on an exposed site. The dramatic free standing brick chimney is built using reinforced masonry. Wee provided a full structural design service from scheme to completion.
