GS Renovation removes load-bearing walls across Coulsdon, from the 1930s semis lining the residential roads off the Brighton Road to the interwar houses that sit on Coulsdon's generous CR5 plots. With over 30 years of structural work in the Croydon borough, we take out internal walls safely and open up these homes without compromising the storeys above.
Assessing a load-bearing wall in Coulsdon
Coulsdon's 1930s semi-detached and interwar houses were built with solid internal walls, and the spine wall running front to back usually carries the first-floor joists and the roof load. Before anything is touched, we bring in a structural engineer to confirm what the wall supports, calculate the loads and size the steel beam or RSJ needed to replace it. Nothing is assumed on a house of this age.
The engineer specifies the beam, its bearings and the padstones it lands on, typically concrete padstones built into the flank or spine masonry. On these interwar plots the ground-floor rooms are a decent size, so a single well-placed beam often opens a through room cleanly. We plan the beam route, the propping positions and the making-good before we lift a single brick.
Safe removal and building control in CR5
Removing a load-bearing wall in a Coulsdon home is a staged job, not a quick knock-through. We install temporary props and needles to carry the load, cut out the masonry in controlled sections, seat the steel onto its padstones, then pack and pin the beam tight to the structure above before the props come down. Working in an occupied CR5 house, we sheet up, manage the dust and keep the place liveable throughout.
This is structural work under the Building Regulations, so it is notifiable to Croydon Council's building control, not a planning matter. We arrange the inspections, present the engineer's calculations and get the beam signed off. Where the wall you are removing meets the party wall shared with the adjoining semi, the Party Wall Act applies and you serve notice on your neighbour before starting.
What the engineer checks in an interwar semi
The survey on a Coulsdon semi looks at three things beyond the wall itself. First, the direction the floor joists run, which decides whether the wall is carrying the floor above or merely dividing rooms, and which is checked by lifting a board rather than tapping the plaster. Second, whether the wall continues up through the first floor, because a partition above the proposed opening adds load that a rule of thumb would miss entirely.
Third, what is under the wall. Interwar houses off the Brighton Road were built with shallow strip footings, and a new beam concentrates load that was previously spread along the whole wall onto two points. Where the engineer is not satisfied the existing footing can take that, the design will call for the foundation to be locally underpinned or widened. Finding that out at survey stage is far cheaper than finding it out with the props already up.
