The Project

This project in Isleworth, West London involved a complete structural and internal transformation of the property.

With planning permission and architectural designs already in place, the client required a reliable construction team to deliver the build, including a side extension, double-storey rear extension and loft conversion, alongside a full internal refurbishment.

A key objective was to create a large open-plan living space without visible structural pillars.

By installing structural steel beams and reconfiguring the layout, we opened up the entire ground floor to create a bright and seamless living environment.
