GS Renovation has installed steel beams across Forest Hill for over 30 years, from the bay-fronted Victorian terraces near the Horniman Museum to the Edwardian homes climbing the leafy SE23 hills. When a load-bearing wall comes out, our RSJs are sized by a structural engineer, bearing onto padstones, with building control sign-off throughout.
Steel beams for Forest Hill terraces
The typical SE23 project removes the wall between the front and rear reception rooms, or the kitchen and the middle room, to open up a narrow Victorian terrace. That dividing wall usually carries the floor joists above and often part of a chimney stack, so a structural engineer calculates the load and specifies the right RSJ. We install padstones to spread the bearing, prop the structure safely and demolish in careful stages so nothing shifts.
Because the party wall between you and the neighbouring terrace is shared, the Party Wall Act frequently applies when a beam bears into it, so you serve the correct notices before work starts. Building control inspects the padstones, the bearing and the fire protection to the steel, then issues the completion certificate. We keep the dust down and the house watertight, whether you live near Telegraph Hill or the streets below.
Load-bearing wall removal in SE23
Not every wall in a Forest Hill terrace is load-bearing, but many homeowners assume wrongly in both directions. We start by investigating the structure above, checking joist direction, chimney breasts and the closet wing at the rear, before anyone swings a hammer. The engineer then decides whether a single RSJ, a pair of beams or a goalpost frame is needed, and we size the padstones and connections to match the actual loads coming down.
Temporary propping is where most of the risk sits, so we support the floors and any masonry above on Acrow props and needles before cutting the opening. Staged demolition keeps the terrace stable and protects the shared party wall from cracking. Once the steel is seated, levelled and bolted, we case it for fire resistance, make good the plaster and hand you a clean opening ready for the next phase of the build.
Why the structural work comes first
If a Forest Hill house is being renovated in stages, the steel goes in before anything else. Cutting a beam into a wall means propping floors, breaking out masonry and replastering both the opening and the ceiling around it, so any new kitchen, flooring or decoration in that room will be disturbed. Doing the structure after the fit-out means paying twice for the same finishes and living through the mess a second time.
It also shapes the design of everything downstream. The final position and depth of the beam decide ceiling heights, where lighting can run, whether units can be full height and whether a door will fit under a downstand. We prefer the engineer's design settled and the steel in before a kitchen is ordered or a floor is laid, because the measurements every other trade works from come from what the structure actually turns out to be. Where a whole house is being done, we sequence the rooms so the steelwork and the messiest trades pass through together.
- Steel delivered cut, drilled and primed to the engineer's schedule
- Steel columns, base plates and bolted connections
- Party Wall Act 1996 notices and awards handled
- Temporary propping and staged, controlled demolition
- Flitch beams where a slimmer steel and timber solution suits
The GS Renovation Difference in Forest Hill
Forest Hill homeowners choose GS Renovation because we treat the structure as the priority, not an afterthought. One team manages the engineer's calculations, the propping and the building control sign-off, so nothing falls between trades. With 30+ years across SE23 and neighbouring Catford, Lewisham and Deptford, we know how these terraces are built and where the loads really go.
- Clean, tidy and reliable tradespeople
- Restricted London access planned before the steel arrives
- A dedicated project manager from first survey to handover
- High-density concrete padstones bedded at every bearing
- Steel ordered cut, drilled and primed to the schedule
- A written scope and programme agreed before work starts
