GS Renovation creates open-plan living across Dulwich, opening up the bay-fronted Victorian and Edwardian terraces of SE21 into bright kitchen-diners and knock-throughs. With more than 30 years of structural experience in Southwark, we turn compartmented period rooms into the connected space families want, with the steelwork engineered to carry the house properly.
Opening up Dulwich period homes
The terraces around Dulwich were laid out as separate front and rear reception rooms divided by that structural spine wall, with a closet wing and side return behind. Knocking front-to-back or drawing the rear room into the kitchen means removing masonry that is carrying real load, so the engineer designs a beam sized for the span and specifies padstones at each bearing before we open anything up.
Whether you want a full knock-through, a generous kitchen-diner extending into the side return, a broken-plan layout with a part-wall retained, or elegant Crittall-style glazed dividers to zone the space, the structural principle is the same. We prop the floors above, cut the opening in safe stages, set the steel onto its padstones and remove the props once it is bearing. The result is open, light-filled and structurally sound.
Consent and party walls in SE21
Opening up the inside of your Dulwich home is governed by the Building Regulations, so this internal structural work needs building control rather than planning permission. Planning or conservation-area consent only applies to exterior alterations, which matters in parts of SE21. Southwark Council's building control inspects the propping, the steel beam and the padstone bearings and issues the completion certificate for your records.
Where the beam for your knock-through bears into the party wall shared with next door, and in these terraces it frequently does, the Party Wall Act applies and we serve notice on the neighbour before starting. We coordinate the whole conversion under one roof: engineer's calculations, party wall notices, careful propping and demolition, Crittall or glazed dividers fitted true, and replastering and making good so the finished open-plan space is ready to decorate.
