Who we are
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 lessons of the past to 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.
Our approach
Involved Early
We like to join while the design is still flexible, so structure and architecture develop together and costly redesign is avoided later.
Collaborative
We work alongside architects, surveyors and contractors to reach safe, buildable and visually appropriate outcomes.
Proportionate
We give clear, evidence-led advice and avoid over-engineering, so the design is efficient as well as sound.

Our work
Church Walk
Church Walk provides four great homes within what seemed an unpromising urban site. The design sought to make memorable housing at high density whilst being neighbourly.
More InfoOatlands Close
We worked with Soup Architects on renovating and extending an existing four-bedroom house on a long north/south axis site in Surrey. The existing house had a very poor connection to a fantastic rear garden.
More InfoBroombank
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.
More InfoRecognition
Our projects have been recognised with the Wood Awards and RIBA regional awards, reflecting a long record of work where engineering and design succeed together.
