We produce all the necessary structural calculations and drawings required for submission to Enfield Council's Building Control department, ensuring your project is compliant and structurally sound.

Local Challenges

House Extensions in Enfield

A primary challenge for extensions in Enfield is the London Clay soil, which necessitates carefully designed foundations to prevent issues from ground movement. We design appropriate trench-fill or piled foundations to manage this risk. Furthermore, Enfield Council's 'Householder Design Guide' sets out clear policies on the scale and massing of extensions to protect neighbourly amenity. Our role is to provide a structural scheme, such as a steel box frame, that enables your desired open-plan layout while adhering to these planning constraints.

Recent Project

Winchmore Hill, Enfield

For a 1930s semi-detached home in Winchmore Hill, we designed the structural elements for a 4-metre deep single-storey rear extension. The design included a steel box frame to create a 6-metre wide opening to the garden, and foundations designed to account for a large oak tree in the neighbouring property.
