GS Renovation installs RSJs and steel beams across Mitcham, from the 1930s semi-detached houses off Mitcham Common to the interwar suburban homes near Morden Hall Park. With over 30 years of structural work in CR4, we remove load-bearing walls safely and hand you a clean, open space signed off by building control.
Removing load-bearing walls in Mitcham semis
The dividing wall between the two ground-floor reception rooms in a Mitcham 1930s semi is almost always load-bearing, carrying the floor above and often a chimney stack. We start with a structural engineer sizing the steel to the actual span and load, then set out padstones so the beam bears properly onto sound brickwork. Nothing is guessed on these interwar houses, where the original layout was built for smaller, separate rooms.
On site we install temporary propping to take the load before any brickwork comes down, then work through a staged, controlled demolition rather than knocking a wall out in one go. Once the RSJ is seated on its padstones and packed tight, we remove the props, fireproof the steel and make good. Merton Council building control inspects the work at the key stages and issues the completion certificate.
Party wall notices on shared Mitcham walls
Many Mitcham properties are semi-detached or terraced, so the wall you want to open up, or the chimney breast you want to remove, sits within a shared party wall with the neighbour. Where that is the case, the Party Wall Act applies and formal notice must be served before work begins. We flag this early so the notice period does not hold up your start date, and we explain exactly which parts of the job trigger it.
We coordinate the structural engineer's calculations, the padstone details and the beam schedule so your neighbour and their surveyor see a properly documented scheme. On the generous plots common in CR4, side extensions and rear knock-throughs frequently involve steel that bears close to the boundary, so getting the party wall paperwork right protects both households and keeps the project moving without disputes.

The GS Renovation Difference in Mitcham
Mitcham homeowners choose GS Renovation because we treat steelwork as engineering, not guesswork. The beam is sized by a structural engineer, propped and staged safely, bedded onto proper padstones and signed off by Merton Council building control.
