Structural Design for Loft Extensions

Local Challenges

Loft Extensions in Hammersmith & Fulham

The main structural challenge is to insert a new floor and supporting steelwork within the tight confines of an existing roof structure while achieving the required headroom. In Conservation Areas like Brackenbury Village, planning policy may dictate the size and materials of dormers, which can influence the structural strategy. Our designs are optimised for buildability and space efficiency.
