Structural Design for House Extensions in Croydon
We provide the structural calculations and drawings required for your house extension in Croydon. Our designs ensure your new space is safe, compliant with Building Regulations, and buildable.

We collaborate with your architect to integrate the structural elements seamlessly into the overall design.
Local Challenges
House Extensions in Croydon
A key challenge for Croydon extensions is managing the London Clay subsoil, which requires carefully considered foundation design to prevent future movement. In densely populated areas like West Croydon, party wall considerations are paramount, and our designs provide the clear details required for Party Wall Agreements. The council's Suburban Design Guide also influences massing and scale, and our structural solutions for roof profiles and large openings are developed to support your planning application's success.

Recent Project
Sanderstead, Croydon
We provided the structural design for a large single-storey rear extension on a 1930s semi-detached house, creating a spacious kitchen-diner. The design included a steel box frame to allow for 5-metre-wide sliding doors, and carefully specified foundations to account for a large protected oak tree in the garden.
