GS Renovation creates open-plan spaces in Eltham, transforming the compartmented ground floors of 1930s and interwar SE9 homes into bright kitchen-diners and connected living areas. With over 30 years across the Royal Borough of Greenwich, we handle the knock-throughs, broken-plan layouts and Crittall dividers, engineering the structure behind every wall we take down.
Open-plan layouts for Eltham's interwar houses
The 1930s semis around Eltham were laid out as separate front and rear reception rooms divided by that load-bearing spine wall, with the kitchen tucked away at the back. Knocking through to a single kitchen-diner or an open living space is one of the most popular changes in SE9, but the dividing wall is structural, so every conversion starts with an engineer sizing the beam that will replace it.
Not every homeowner wants one big room. Broken-plan works beautifully in these generous Eltham layouts, using a part-height wall, a wide steel-framed opening or a Crittall-style glazed divider to separate cooking from lounging while keeping the light and space flowing. Whatever the look, the load path is engineered first, then the steel is propped, seated on padstones and hidden within the finished ceiling.
Getting a knock-through signed off in SE9
An internal open-plan conversion is governed by the Building Regulations rather than planning, so unless your Eltham home is listed or within a conservation area there is no planning application to submit. Building control matters, though: the Royal Borough of Greenwich or an approved inspector checks the beam, its bearings and the padstones, and considers ventilation and any effect on means of escape in the new layout.
As the spine wall in an attached SE9 semi often meets the party wall, and one end of the new beam bears into it, the Party Wall Act commonly applies and you serve notice on the neighbour first. We coordinate the engineer, the propping and the building control inspections, then finish the opening cleanly so your new kitchen-diner feels like it was always one room.
