GS Renovation removes load-bearing walls across Wembley, from the 1930s semi-detached houses near Wembley Stadium to the interwar suburban homes on generous HA9 plots. With over 30 years of structural work in Brent, we take out internal walls safely, install a properly sized steel beam and give you the wider, brighter ground floor these houses were built to allow.
Taking out a load-bearing wall in Wembley
Wembley's interwar semis were laid out with small, separate rooms: a front reception, a rear dining room and a galley kitchen behind. The spine wall running front to back usually carries the floor joists above and, in these houses, a slice of the roof load too. Because that wall is doing structural work, we never touch it until a structural engineer has calculated exactly what it holds and specified the steel needed to replace it.
The engineer sizes an RSJ or a pair of beams to span the new opening, and we set them onto concrete padstones that spread the load into the remaining masonry each side. Before any brickwork comes down we install temporary props, take the wall out in controlled stages, lift the steel into place and only then remove the props. It is methodical work that keeps a 1930s house stable throughout.
Building control sign-off across HA9
Removing a load-bearing wall is governed by the Building Regulations, not planning permission. You do not need planning consent to open up the inside of an interwar semi in HA9, unless your home is listed or the exterior sits in a conservation area. What you do need is building control approval, and Brent Council's building control team inspects the beam, the bearings and the padstones before the work is signed off and certified.
Where the spine wall meets the party wall shared with the neighbouring semi, or where a beam bears onto that shared wall, the Party Wall Act applies and notice must be served next door before work begins. We handle the engineer's calculations and the building control booking as one package, so nothing on the compliance side is left for you to chase.
Bearing a beam into a cavity wall
The interwar houses behind the stadium were among the first built with cavity walls, and that changes how a beam lands. A cavity wall is two separate leaves with a gap between them, and only the inner leaf carries the floor loads, so the padstone bears on that inner leaf alone rather than across both. Sitting a padstone on both leaves bridges the cavity and gives damp a path across it.
So the detail matters. The engineer sizes the padstone for the width available on the inner leaf, which is often less than people assume, and where the bearing pressure is too high the answer is a longer padstone, a spreader plate or a column. Any masonry cut back at the bearing is rebuilt with the cavity kept clear, and where insulation is disturbed it is reinstated so the bearing does not become a cold spot that collects condensation in winter.
