GS Renovation opens up Barnet homes, turning the compartmented layouts of 1930s semis into bright kitchen-diners and knock-through living spaces. From N2 and N3 through to the interwar houses of Mill Hill and NW11, our 30+ years of structural experience means the walls come down safely and the new steel disappears into the ceiling line.
Knock-throughs in Barnet's 1930s semis
The classic Barnet semi separates a front reception from a rear dining room with a load-bearing spine wall, and knocking the two together is the single most popular change we make in N3, N12 and NW4. Because that wall carries floor and roof loads, the opening needs a properly sized steel beam, not just a lintel, and the engineer specifies the section to span the full width of the room.
For a true open-plan feel we can take the wall out completely and set a flush beam up into the ceiling zone, so the finished space reads as one room with no downstand interrupting the line. Where clients prefer broken-plan, we form a wide structural opening or frame it with a Crittall-style glazed divider, keeping a sense of separation while the light still travels through the generous interwar footprint.
Kitchen-diners and building control in Barnet
Opening up the ground floor of a Barnet house is controlled under the Building Regulations rather than planning, so Barnet Council building control inspects and certifies the beam and its bearings. Planning only enters the picture if you are also altering the exterior, and homeowners within Hampstead Garden Suburb's conservation area should note that its controls apply to the outside of the property, not to internal steelwork like this.
Most of these knock-throughs involve the spine wall, but where an opening reaches a party wall shared with the neighbouring semi the Party Wall Act applies and we serve notice first. We prop the floor above, remove the wall in stages, bed the steel on padstones and then handle the plastering, flooring and making good so your new kitchen-diner is finished, not just structurally opened up.
