SFS Extensions
Built with commercial steel precision
SFS is like building your extension using the skeleton of a skyscraper — but scaled for a home.
Instead of relying on brick walls to hold weight, a precision steel frame carries the structure, while the walls become high-performance insulated layers around it delivering faster build programmes, greater structural stability, and a higher standard of finish long-term.
