GS Renovation removes load-bearing walls across Barnet, from the 1930s semis of Finchley and N3 to the substantial interwar houses around Mill Hill and NW7. With more than 30 years of structural experience across N2, N12, NW4 and NW11, we take out internal walls safely, install the right steel and leave a clear, supported opening.
Load-bearing walls in Barnet's 1930s semis
The typical Barnet semi was built between the wars with a solid spine wall running front to back, and that wall usually carries the floor joists and part of the roof load above. Before anything is touched, our structural engineer inspects the wall in your Finchley or Hendon home, works out exactly what it supports, and sizes a steel beam to carry that load once the masonry comes out.
Once the beam is specified we prop the floor above temporarily, cut out the wall in careful stages, and lower the RSJ onto padstones bedded at each end to spread the load into the remaining structure. In the generous through-rooms of these interwar houses that often means a single long span, so we size the steel and its bearings for the full width rather than patching in an undersized section.
Building control sign-off across N3 and NW7
Removing a load-bearing wall inside your home is governed by the Building Regulations, not planning permission, so there is no planning application for the work itself. Barnet Council's building control service inspects the beam, its bearings and the propping, then issues the completion certificate you will need when you come to sell. The exception is Hampstead Garden Suburb, where its conservation-area status only affects external alterations, not this internal steelwork.
Many Barnet semis share a party wall with the house next door, and where a new beam bears into that shared wall the Party Wall Act applies. In that case we serve notice on your neighbour before work begins. We handle the engineer's calculations, the notices and the building-control booking together, so nothing stalls midway and the job stays on one accountable timeline from first inspection to final certificate.
