GS Renovation removes load-bearing walls throughout New Malden, from the 1930s semi-detached houses off the Kingston Road to the wider interwar streets running down towards Surbiton. With over 30 years of structural work across KT3, we open up these family homes safely and sign every job off with Kingston Council building control.
Load-bearing walls in New Malden's interwar semis
The typical New Malden semi was built in the 1930s with a solid spine wall running front to back, carrying floor joists and often a stretch of first-floor masonry above. On these generous suburban plots homeowners frequently want the back reception knocked into the kitchen, but that spine wall is usually load-bearing, so we never touch it until a structural engineer has confirmed exactly what sits on top.
Our engineer sizes a steel beam to carry the load once the wall comes out. The beam bears onto padstones at each end, spreading the weight into the remaining brickwork or a new pier. We install temporary props, take the wall down in controlled stages, lift the steel into position and only then remove the propping, so the structure is supported at every moment.
Building control sign-off across KT3
Removing a load-bearing wall inside a New Malden house is a building regulations matter, not a planning one. You do not need planning permission for this internal work; instead the engineer's calculations go to Kingston Council building control, who inspect the propping, padstones and finished steel before issuing completion. We book those inspections and hand you the certificate at the end.
Because these are semi-detached houses, one flank of the property shares a party wall with next door. Where a new beam bears into that shared wall, the Party Wall Act applies and notice must be served on the adjoining owner. We identify that early, prepare the notices and keep the neighbour informed so the job runs without disputes or delays.
How wide the opening should really be
A full-width opening is not automatically the best answer in an interwar semi. The wider the span, the deeper the beam, and a deep downstand in a room with a standard 1930s ceiling height eats into the sense of space it was meant to create. There is also a practical loss: two rooms have four usable walls between them, and one long room has considerably fewer places to put a sofa, a television or a dresser.
Leaving a short return of masonry at each end often gives a better room. It shortens the span, keeps the beam shallower, provides somewhere for a radiator or a switch, and preserves a little separation between the two ends of the space. We mark out different widths on the floor with tape before anything is instructed, so you can stand in the room and see the difference rather than judging it from a drawing.
- Building control notification and inspection sign-off
- Dust screens and floor protection through occupied rooms
- Joist ends supported where the wall carried the floor above
- Lintel replacement where an existing opening has failed
- Final level checks before the temporary props come out
