GS Renovation creates open-plan spaces in Finchley homes, opening up the compartmentalised rooms of 1930s semis into bright kitchen-diners and sociable living areas. With over 30 years across Barnet, we handle knock-throughs, broken-plan layouts and Crittall dividers in N3, engineering every opening properly so the interwar house above stays fully supported.
Open-plan living in Finchley's interwar houses
Interwar houses in Finchley were designed as a series of separate rooms, with the kitchen tucked at the back and a wall dividing it from the dining room. Knocking these together is the most popular project we do in N3, turning a dark rear kitchen into an open kitchen-diner that runs across the generous width of the plot. The dividing wall is usually load-bearing, so an engineer specifies the beam before anything comes down.
Not every family wants one big room. Broken-plan layouts keep a sense of zones using a half-height wall or a steel-framed Crittall screen, which suits the period character of these 1930s homes and lets light travel through while still separating cooking from living. Whether it is a full knock-through or a subtle divider, the structural principle is the same: support the load above on a correctly sized steel and padstones.
Compliant open-plan conversions across N3
The steel beam that spans a knock-through is sized by a structural engineer, bears onto padstones set into sound masonry, and goes in behind temporary propping with the wall removed in staged, controlled sections. All of this is controlled under the Building Regulations and signed off by Barnet Council building control, not planning, so the internal reconfiguration itself does not need a planning application.
In a semi, the wall you are opening up often ties into the party wall shared with next door, so where the new beam bears into that shared wall the Party Wall Act applies and we serve notice on the neighbour. We coordinate the engineer, the notices, the building control inspections and the finishing trades, so your new open-plan Finchley space is delivered as one clean, compliant project.
