Load-Bearing Wall Removal & RSJ Installation in London

Knocking the kitchen and dining room into one is the most common change Londoners make. When the wall is load-bearing it needs a steel beam, structural calculations and Building Control approval, and we handle all three.

Questions we're often asked
Do I need Building Control for an RSJ?

Yes. Removing a load-bearing wall always needs approval, and you'll need the certificate when you sell.

Do I need a Party Wall agreement?

If the beam bears into a shared wall, usually yes.
