GS Renovation removes load-bearing walls throughout Eltham, from the bay-fronted 1930s semis off the high street to the interwar suburban houses set back on their generous SE9 plots. With over 30 years of structural experience across the Royal Borough of Greenwich, we open up ground floors safely, size the steel and leave a level, certified result.
Load-bearing walls in Eltham's 1930s semis
Eltham's interwar semi-detached houses were built with a solid load-bearing spine wall running front to back, usually separating the front reception from the rear living room and carrying the floor joists and the wall above. Homeowners in SE9 nearly always want this spine opened up, but it is holding real weight, so we never touch it until a structural engineer has confirmed exactly what sits on top.
The engineer sizes a steel beam to carry the load once the masonry is gone, and specifies the padstones it bears onto at each end. On these 1930s plots the party wall with the attached neighbour often forms one bearing point, so we design that support carefully. We then prop the floors above, remove the wall in stages, seat the beam and make everything good.
Building control sign-off across SE9
Taking out an internal load-bearing wall is structural work governed by the Building Regulations, not planning permission, so unless your Eltham home is listed or in a conservation area there is no planning application to make. The support does need building control, and the Royal Borough of Greenwich, or an approved inspector, inspects the beam, the padstones and the bearings before signing the job off.
Because these interwar semis share a party wall with the house next door, and one end of your new beam frequently bears into that shared wall, the Party Wall Act applies and notice is served on the neighbour first. We handle the engineer's calculations and the building control application, then complete the works as one accountable team with no loose ends.
How long the work takes from start to finish
A single opening in an SE9 semi is not a long job on site, but it is not a two-day one either. Allow time for the engineer's visit and calculations before anything starts, and for the building control application and any which run to their own timetable. Once we are in, protection and diverting services take the first day, propping and demolition the next, and the beam usually lands shortly after that.
Then it slows down deliberately. The bearings stay open until building control has seen them, the props stay in until the padstone mortar has gained strength, and only then is the steel encased and the opening plastered. Fresh plaster needs to dry before it is painted, longer in winter, and it wants a mist coat first. Rushing the decoration is the most common way a sound opening ends up looking patchy six months later. We give you a realistic sequence at the outset so you know which weeks are noisy and which are simply waiting.
