Open-plan kitchen, diner and living conversions in Bromley. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Bromley, turning the compartmented rooms of 1930s semis around Beckenham, Orpington and Chislehurst into bright kitchen-diners and knock-throughs. With 30+ years across BR1, BR2, BR5 and BR6, we handle everything from full open-plan layouts to broken-plan zoning with Crittall dividers in these interwar homes.

The classic Bromley open-plan project is joining the two reception rooms of an interwar semi, or opening the kitchen into the dining room to make a single sociable space that suits the generous rear plots common in BR6 and BR7. The wall between them is nearly always load-bearing, carrying floor joists and part of the roof, so the layout you want depends on a beam the structural engineer sizes for the full span.
We install a correctly sized steel on padstones, prop the structure temporarily while it goes in, and demolish in stages so the house stays stable throughout. Once the steel is in, we can create a wide, clean opening or a full knock-through, then finish it flush so the beam disappears into the ceiling line and the two spaces read as one.
Not every Bromley homeowner wants a single cavernous room. Broken-plan is popular in these interwar houses, using a part-height wall, a change in level or a Crittall-style glazed divider to zone a kitchen-diner while keeping light flowing through. Where a divider replaces a structural wall, the steel still does the structural job and the glazed screen is hung within the new opening, so the engineering and the styling work together.
This internal work is governed by the Building Regulations rather than planning, and Bromley Council's building control signs off the beam and its bearings. Where the wall being altered is the party wall shared with the adjoining semi, you serve Party Wall Act notice on the neighbour first. We coordinate engineer, notices, steelwork and finishing as one job, from first sketch to certified, decorated space.
Bromley homeowners choose GS Renovation for open-plan conversions because we own the whole transformation: engineer-sized steel for the knock-through, padstones and safe staged demolition to the adjoining semi, and Bromley building control sign-off, plus tidy finishing whether you want full open-plan or a broken-plan Crittall divider. It is all delivered by one accountable team with 30+ years in the borough.

FAQ
We would rather not, because a phone figure is a figure that changes. What open-plan conversion costs at a BR1 address depends on structure and condition we can only see on site, particularly in interwar semi-detached housing. GS Renovation will happily talk through the likely scope on 07472 424 226, then survey the Bromley property free of charge. The written quotation follows that visit. Nothing is owed for the BR1 visit, in Bromley or anywhere beyond it. 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.
Between two and a handful, depending which week of the open-plan conversion programme you are in. GS Renovation employs its own team for the structural work at a BR1 address and coordinates the following trades directly, rather than passing your Bromley job to a chain of subcontractors. That is what keeps the Bromley site tidy and accountable. The same manager is there throughout. Ring 07472 424 226 and we will describe the team running open-plan conversion at a BR1 address.
Paperwork is where open-plan conversion projects quietly lose time, so we take it on. GS Renovation runs the Bromley Council application and inspections for your BR1 property alongside the works programme, which keeps the Bromley job moving. The engineer's design, where the structure requires one, is coordinated by us as well. You receive the certificate at completion. Ring 07472 424 226 to hear how a Bromley application runs. The certificate matters when a Bromley property changes hands.
Where the dividing walls are non-structural partitions, usually yes, but the lease and the freeholder's licence to alter come first. In a BR1 flat we confirm with an engineer what is carrying load before agreeing any layout.
Usually earlier alterations that were never done properly. Open-plan conversion at a BR1 property of that age regularly uncovers removed structure, notched joists or wiring that predates any certificate, and each is costed and agreed before we continue. GS Renovation names the likely candidates at the Bromley survey. Bromley Council is notified where a change affects approved work. Ask on 07472 424 226 what open-plan conversion commonly uncovers at a BR1 address of that sort of age.
Almost always, yes. In a typical Bromley interwar semi the dividing wall is load-bearing, so we have a structural engineer size a steel beam to carry the span, then prop, remove the wall in stages and bear the steel onto padstones. Bromley building control signs it off, and if the wall is shared with next door you serve party wall notice first.
Yes, from any part of Bromley and the BR1 area, and from the surrounding Bromley too. GS Renovation quotes open-plan conversion free of charge with no obligation, whether the property is at BR1 or over towards Lewisham. If we are not the right firm we will tell you rather than quote and hope. Ring 07472 424 226 and we will book a survey. Small jobs are as welcome as large ones. Building control is coordinated where the work requires it.
