Open-plan kitchen, diner and living conversions in Bexley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Bexley, opening up the compartmented layouts of the borough's 1930s semis and interwar houses in Bexleyheath, Sidcup and Welling. With 30-plus years in DA5, DA7 and DA15 we knock through to kitchen-diners, form broken-plan living areas and fit Crittall-style dividers, all engineered and signed off by building control.

Bexley's interwar houses were designed as a series of small separate rooms, so the classic project here is knocking through the load-bearing spine wall to join the kitchen and rear reception into one bright kitchen-diner facing the garden. Because that wall carries the floor and roof above, a structural engineer sizes the steel beam and specifies the padstones before the wall comes down.
For homeowners who want light to flow without one cavernous space, we create broken-plan layouts and fit Crittall-style glazed dividers, giving a defined kitchen and sitting area that still share light and views across the generous ground floors these houses enjoy. We prop, remove the wall in staged sequence, set the beam and finish flush so the transition looks original.
A knock-through is governed by the Building Regulations rather than planning, so unless your Bexley home is listed or in a conservation area no planning application is needed for the internal work. Bexley Council building control inspects the beam, bearings and any new structure, and issues the completion certificate for your records.
As the spine wall in a semi ties into the shared party wall, opening it up can be notifiable under the Party Wall Act, and you serve notice on your neighbour before starting. From the engineer's calculations to the steelwork, the Crittall glazing and the final plaster and flooring, we deliver the whole open-plan conversion as one coordinated job.

FAQ
Often a little, and the reason is making good rather than the structural work. Bay-windowed 1930s semis with side access and separate garages rarely have regular dimensions, so open-plan conversion at a DA1 address takes more time in plaster and joinery than in a newer house. GS Renovation allows for that in the Bexley quotation instead of discovering it midway. The structural element itself is usually comparable. Ring 07472 424 226 and GS Renovation will explain what your DA1 property is likely to need. 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.
Book the survey now and decide later, because that costs nothing. It gives GS Renovation the information to programme open-plan conversion at your DA1 home and gives you a real date rather than an estimate. Demand across Bexley and Bexley varies with the season. We will always tell a South East London client honestly when the next slot genuinely is. The survey at DA1 costs nothing and commits a Bexley homeowner in Bexley to nothing.
Aftercare is part of the job rather than an afterthought. Once open-plan conversion at your Bexley home is complete, GS Renovation provides the Bexley Council certificate, the engineer's documentation where the design required one, and the guarantee on installations. Snags at DA1 are dealt with by the same team. Most of our Bexley work comes from people we have already looked after. Email info@gsrenovationltd.co.uk to reach us. The certificate and the guarantee are handed over together at DA1.
It can, and building control will look at it closely. Opening a hallway into a living space in a Bexley property removes the protected route to the front door, so interlinked alarms and sometimes a protected alternative are required. We resolve that with Bexley Council at design stage.
The load path first, then the condition of what remains. Open-plan conversion at a DA1 address of that age needs the structure confirmed by an engineer, the timber checked for decay, and any earlier alteration assessed before design. GS Renovation coordinates all of it and submits to Bexley Council. That is what stops a fixed Bexley price from moving. Ring 07472 424 226 and we will explain the open-plan conversion checks required at a DA1 property.
In most Bexley interwar semis, yes. The dividing spine wall is usually load-bearing, so a structural engineer sizes a steel beam to carry the floor above once it is removed. The work is controlled under Building Regulations, not planning, and where the wall meets the shared party wall the Party Wall Act may apply. We handle the engineering, building control throughout.
Give us the postcode and you will have an answer immediately. We cover Bexley and the surrounding Bexley for open-plan conversion, including addresses that sit right on the edge of DA1. GS Renovation is on sites nearby most weeks. If we are not the right firm for your interwar semi-detached property we will say so. Email info@gsrenovationltd.co.uk and we will come back the same day. Nothing is owed for the reply or the DA1 survey.
