GS Renovation installs RSJs and steel beams across Lambeth, from the Georgian townhouses of Kennington to the Victorian terraces around Clapham Common. With over 30 years of structural experience in SE11, SW4 and SW9, we open up period homes safely, with beams sized by a structural engineer and signed off by building control.
Steel beams for Lambeth period homes
Lambeth's Georgian and Regency townhouses were built with solid brick walls and internal load-bearing partitions, so removing a wall to create flow means transferring real weight onto a new steel. In SW2 and SE24 we work with your structural engineer to size the RSJ, cast or supply padstones at each bearing, and install temporary propping before any masonry comes down. Every stage is planned so the structure above stays supported throughout.
Because many Lambeth homes sit within conservation areas or carry listed status, we keep steelwork discreet, dropping beams into the ceiling line where head height allows and boxing them cleanly afterwards. We stage demolition carefully in occupied houses around Brixton and Streatham, protecting original cornicing and floors. Once the beam is bearing correctly on its padstones, building control inspects the work before we close everything up.
Party wall steelwork across Lambeth terraces
A large share of Lambeth's terraces and semis share a party wall with the neighbouring house, and chimney breasts and dividing walls often sit right on that boundary. Where your beam bears into a shared wall, the Party Wall Act applies, so you serve the correct notices on adjoining owners in good time. This keeps SW8 and SE27 projects lawful and avoids disputes once the drilling and cutting begin.
We handle the practical side too, from propping the floors above to protecting the neighbour's side of the wall during breaking out. Our teams work to a sequence agreed with building control, so inspections happen at the right moments and nothing is hidden. Whether you are removing a chimney breast in Vauxhall or a spine wall in Clapham, the steel is specified, installed and certified to keep your home sound for decades.
Needles, props and holding the house up
The temporary works are the part of a steel installation that keeps everyone safe, and they are designed rather than improvised. Where the wall carries a floor and a wall above, we cut needles, short beams passed through holes in the masonry above the line of the new opening, and prop them from below on both sides. That takes the load off the wall before a single brick is removed.
Props have to stand on something solid. On a suspended timber ground floor in a Lambeth terrace that means spreader plates across the joists, or taking the props down to a solid base below. The propping stays until the beam is seated and packed tight to the masonry above and the padstones have gained strength. Striking props early is one of the few genuine ways to cause damage on this kind of job, so it happens in order rather than to suit a diary.
