Open-plan kitchen, diner and living conversions in East Barnet. Trusted, professional, 30+ years' hands-on experience.
GS Renovation opens up East Barnet homes, joining the small rear rooms of Victorian terraces near the village into one kitchen and dining space, and knocking through the compartmented ground floors of the interwar semis around it. With over 30 years of structural work in EN4, we prop and beam and certify every opening properly, then hand over the paperwork at the end.

The terraces near the village have a familiar plan: two small rooms front and back, then a narrower rear addition holding the original scullery. The popular scheme joins the back reception to that addition and takes the side return into the room, which gives a genuinely wide kitchen out of two cramped spaces. It is more structural work than it looks. You are usually removing part of a load-bearing internal wall and the flank of the rear addition, which means a beam, sometimes two picking up on a post, all designed by the engineer we appoint.
Floor levels are the detail that gets forgotten. The original rear addition of an EN4 terrace often sits a step down from the main house, or has been rebuilt in concrete against a suspended timber floor elsewhere, so once the wall between them is gone you have two floors at different heights and a single kitchen sitting across both. We level with a screed or a ply overlay before anything is laid, so the finished floor runs through in one plane. The same applies to the ceiling line, which rarely matches either.
One big room behaves differently from three small ones. The radiators that used to be on the wall you removed have gone, the volume to heat has grown, and a solid walled Victorian terrace loses heat faster than the cavity built semis further out, so the heating needs rebalancing and often resizing rather than reconnecting. Cooking noise and smells travel too, which is why extract matters more in an open plan kitchen than a closed one. We plan the duct run to an outside wall at design stage, not once the units are in.
The structural side is controlled under the Building Regulations, so Barnet Council building control or an approved inspector reviews the calculations and inspects the beam bearings before they are covered. Planning permission does not come into an internal reconfiguration. Where the opening reaches the wall shared with next door, or a beam bears into it, the Party Wall etc. Act 1996 applies and notice is served by you before we begin. Fire and escape also get a look in an open plan house, particularly where the stair now opens directly into the kitchen.
East Barnet families choose GS Renovation for open plan work because the steel is only half of it. We deal with the level change between the old scullery and the main house, the heating that no longer suits one large room, the extract route, the party wall detail and the Barnet building control inspections. One team, one programme, and a house that stays liveable while we work.

FAQ
Yes, wherever the scope can be pinned down at survey. GS Renovation quotes open-plan conversion as a fixed project price for most East Barnet homes, covering labour, materials and the Barnet Council element. Where a genuine unknown sits behind plaster at the EN4 property we say so before starting rather than hiding it in a vague figure. Any variation is agreed in writing. Ring 07472 424 226 and GS Renovation will explain what fixing an EN4 price depends on. As a rough guide, open-plan conversion in London typically costs from roughly £3,000 to £8,000 or more, including the steel beam and finishing (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
You hear it from us first, with the reason and the revised dates. If open-plan conversion at your EN4 property runs beyond the programme, GS Renovation explains whether the cause is a discovery in an interwar semi-detached structure, a Barnet Council inspection slot or something of ours. Fixed-price work does not become more expensive because it took longer. The East Barnet updates continue weekly regardless. Ring 07472 424 226 and GS Renovation will explain how an EN4 overrun is handled.
Our own team, led by one named project manager who is there from survey to handover. Open-plan conversion at an EN4 address is not passed to a chain of subcontractors, so you are dealing with the people doing the work rather than a sales office. Specialist trades are coordinated directly by GS Renovation. The same manager runs your East Barnet job throughout Barnet. Ring 07472 424 226 and ask who that would be. Ask for Barnet references at the EN4 survey.
Where the dividing walls are non-structural partitions, usually yes, but the lease and the freeholder's licence to alter come first. In an EN4 flat we confirm with an engineer what is carrying load before agreeing any layout.
There can be, and we check before any design work begins. Conservation area status, an Article 4 direction or a listing removes permitted development rights at an EN4 address, so open-plan conversion may need a full application to Barnet Council. GS Renovation establishes the position for your East Barnet home first. Building regulations apply regardless of the planning route. Ring 07472 424 226 and we will confirm the designation before any open-plan conversion design work at EN4.
In an East Barnet terrace, think about heat and noise before you decide. A fully open ground floor in a solid walled Victorian house can be lovely in June and expensive in January, and the television competes with the extractor fan. Broken plan is often the better answer here: take the wall out, then put back a glazed screen or a half height wall so the space reads as one but the front room can still be shut off. Structurally it makes no difference, since the beam is doing the same job either way.
Flats included, throughout East Barnet and Barnet. The extra step on an EN4 flat is the licence to alter from the freeholder, and on open-plan conversion involving structure the managing agent will want the engineer's design too. GS Renovation coordinates all of that. Email info@gsrenovationltd.co.uk with the address for a free survey. Nothing is owed whether the East Barnet work proceeds or not. The lease itself governs what is possible at an EN4 address.
