GS Renovation opens up Sidcup's 1930s semi-detached and interwar homes, from simple knock-throughs to full kitchen-diners, broken-plan layouts and Crittall glazed dividers. With 30+ years across DA15 and the Bexley borough, we combine the structural engineering these solid-walled houses need with a clean, well-finished result that suits their generous proportions.
Open-plan living in Sidcup's 1930s semis
The interwar semis around Sidcup were designed as a series of separate rooms, which feels dated against how families want to live now. The classic project here is knocking the front reception through to the rear so the kitchen, dining and living space flow into one, taking full advantage of the generous plots and the outlook onto rear gardens. Because the dividing wall is usually load-bearing, the flow depends on getting the steelwork right.
We ask a structural engineer to size a steel beam for the span, specify the padstones at each bearing and confirm where the load lands. In a Sidcup semi that often means the beam picks up on the flank wall and a retained pier, and we can flush the steel into the ceiling line so the finished room reads as one clean space rather than an obvious opening with a downstand across it.
Broken-plan and Crittall dividers in DA15
Not every DA15 owner wants one big open box. Broken-plan keeps a sense of separate zones while removing the solid walls, using a part-height return, a change in level or a Crittall-style glazed screen to divide the kitchen-diner from a quieter sitting area. These steel-framed glazed dividers suit the period feel of an interwar house and let light travel through the plan without closing rooms off from one another.
Whether you go fully open or broken-plan, removing structural walls is a Building Regulations job that Bexley Council's building control inspects and signs off, not a planning matter, unless the property is listed or in a conservation area. Where an opening runs into the party wall shared with the attached neighbour, the Party Wall Act also applies and you serve notice. We coordinate the engineer, notices and inspections throughout.
