GS Renovation creates open-plan spaces across Purley, transforming the compartmentalised layouts of 1930s semis and interwar suburban houses into flowing kitchen-diners and broken-plan living. With more than 30 years working in CR8, we handle the structure behind every knock-through, so the openings are engineered, propped and signed off, not just knocked through.
Opening up Purley's interwar layouts
The generous plots of Purley gave its interwar houses good-sized rooms, but they were designed as separate boxes: a front reception, a rear dining room and a galley kitchen behind. The most popular conversion here is removing the wall between the dining room and kitchen to make a single kitchen-diner opening onto the garden, or a full knock-through linking front to back across the ground floor.
Almost every one of these walls is doing structural work in a 1930s semi, carrying the joists above, so a genuine open-plan scheme is a steel job first and a decorating job second. We bring in a structural engineer to size the beam for the span you want, whether that is a broken-plan arrangement with a partial return or a clean wide opening with a Crittall divider framing the two zones.
Knock-throughs done properly in CR8
On site we prop the floors, remove the wall in controlled stages, then set the steel on its padstones before loading the structure back and striking the props. The result on a Purley semi is a bright, connected space, but the discipline behind it is what keeps the house safe, and it is why we never treat a load-bearing knock-through as a quick weekend job.
This is Building Regulations work, overseen and certified by Croydon Council's building control, not something that needs planning permission for an internal layout change. Where the opening reaches the flank wall shared with the neighbouring semi and the steel bears into that party wall, the Party Wall Act applies and we serve notice next door. Crittall dividers are a favourite finish here, giving light and separation without closing the room back in.
