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 The engineer sizes 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 you serve notice on your neighbour before work begins. We handle the engineer's calculations and the building-control booking together, so nothing stalls midway and the job stays on one accountable timeline from first inspection to final certificate.
When the inspector calls and what for
Building control does not attend continuously, it attends at set points. On a Barnet wall removal the first visit usually comes once the props are in and the opening is formed but the beam is not yet loaded, so the inspector can see the temporary support and the condition of the masonry at each end. The second, and the one that governs everything, is when the beam is seated on its padstones and the bearings are still open to view.
That second visit shapes the programme. Nothing is boxed, boarded or plastered over a bearing until it has been seen, because uncovering it later is slow and expensive. The inspector will want the engineer's design on file and will check the fire protection to the steel. A final visit follows once making good is done, and the completion certificate that arrives afterwards is the document a buyer's solicitor asks for when you come to sell.
