GS Renovation removes load-bearing walls across Mitcham, from the 1930s semi-detached houses near Mitcham Common to the interwar terraces spread across CR4. With more than 30 years of structural work in Merton, we open up these solid-brick homes safely, size the steel correctly and leave a clean, certified result.
Solid interwar walls in Mitcham homes
Mitcham's 1930s semis and interwar suburban houses were built with load-bearing internal walls carrying the floors and roof above. Homeowners near Morden and Wimbledon often want to open the ground floor, but the spine wall between the front reception and rear kitchen is almost always structural. Before any brick is touched, we bring in a structural engineer to establish exactly what the wall supports and how far the load travels down through the house.
The engineer sizes a steel beam for the span and calculates the bearing at each end. In these generous-plot interwar houses the beam typically lands on new padstones set into the existing brickwork or onto a fresh pier. We work out where the load discharges to solid ground, because the wall you remove upstairs still has to be carried all the way to the foundations without cracking the fabric above.
Safe removal and building control in CR4
On site we install temporary props to take the floor and roof loads before a single course comes out. The wall is removed in careful stages, the padstones are bedded, and the sized steel is lifted into position and packed tight so it starts carrying immediately. Only once the beam is fully bearing do we strike the props. This staged sequence keeps a Mitcham home stable and the family safe while an occupied house stays liveable.
Removing a load-bearing wall is notifiable under the Building Regulations, not planning, so Merton Council's building control inspects and signs off the work. We handle the whole process: the engineer's calculations, the building notice or full plans, inspections at propping and completion stage, and the final certificate. Where the wall ties into a shared party wall with the neighbouring semi, we also serve the correct Party Wall Act notices first.
