Open-plan kitchen, diner and living conversions in Havering. Trusted, professional, 30+ years' hands-on experience.
GS Renovation creates open-plan spaces across Havering, turning the divided ground floors of interwar semis in Hornchurch, Romford and Upminster into bright kitchen-diners and knock-throughs. With 30+ years in RM1, RM11 and RM12, we combine reception rooms, open up to the garden, and can frame it with Crittall dividers for a broken-plan finish.

The 1930s and interwar semis around Havering were laid out as separate front and back rooms with a small kitchen behind, and the generous plots near Raphael Park and Hornchurch Country Park make them ideal candidates for opening up. The most popular change is a knock-through between the rear reception and kitchen to form a family kitchen-diner that looks out over the garden the house was built around.
The dividing wall carrying this layout is almost always load-bearing, so a structural engineer sizes a steel beam and specifies padstones before the wall comes down under temporary props. For those who want light without one vast room, we can set a Crittall-style glazed divider into the opening, giving a broken-plan feel that keeps cooking smells and noise where they belong while the space still reads as one.
Opening up your ground floor is governed by the Building Regulations rather than planning, so Havering Council's building control reviews the beam design and inspects the bearings and propping before certifying the work. Planning only enters the picture for external alterations on a listed building or within a conservation area, which is separate from the structural approval a knock-through needs.
Where the load runs into the wall shared with the adjoining semi, the Party Wall Act applies and you serve notice on your neighbour before cutting in the beam. We coordinate the engineer, the safe staged demolition and the building control sign-off, then make good, plaster and finish the opening, so your kitchen-diner arrives complete from one team rather than a string of trades.
Havering homeowners choose GS Renovation for open-plan conversions because we deliver the whole thing under one roof: engineer-designed beams, building control sign-off, safe demolition and a clean plastered finish, with optional Crittall dividers. Tidy working in an occupied home and 30+ years across the borough's interwar streets sit behind every knock-through.

FAQ
Accurate, because it is written after a survey rather than before one. GS Renovation inspects the RM1 property, confirms what open-plan conversion requires there, and prices the structure, the trades and the Havering Council approvals against that scope. The figures hold unless you change the specification or the interwar semi-detached building reveals something nobody could see. Both possibilities are explained beforehand. Ring 07472 424 226 to hear how a Havering figure for open-plan conversion is built up. 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.
Very little, provided the inspections are booked ahead. Havering Council needs to see the structural work on an open-plan conversion job at an RM1 property before it is concealed, so GS Renovation schedules those visits into the Havering programme rather than calling at the last minute. The completion certificate follows the final inspection. Waiting on paperwork in Havering is a planning failure, not an inevitability. GS Renovation attends every Havering Council inspection at the RM1 property on your behalf.
A five year guarantee applies to installations, and it is backed by a real company. We are GS Renovation Ltd, number 14611254, fully insured, which a Havering homeowner can verify before open-plan conversion begins at RM1. The Havering Council certificate covers the regulated element. GS Renovation would rather you checked all of it than took our word. Email info@gsrenovationltd.co.uk and we will send the Havering paperwork. Verification takes a Havering homeowner about a minute.
It can, and it is worth planning for. One large space in an RM1 property behaves differently to two small ones, so radiator sizing or underfloor heating is reconsidered as part of the Havering conversion rather than left as it was.
We can, and we would tell you early if we could not. Open-plan conversion in bay-windowed 1930s semis with side access and separate garages occasionally runs into a structure that will not do what the owner hoped, and finding that out at the RM1 survey is far better than on site. GS Renovation is honest about it before a Havering client commits. The visit is free either way. Havering Council building control is coordinated by GS Renovation on every open-plan conversion project in Havering.
In most of Havering's 1930s and interwar semis, yes. The wall between the rear reception and kitchen is usually load-bearing, so a structural engineer sizes a steel beam on padstones and we remove the wall under temporary props. Havering Council's building control signs it off under the Building Regulations, and where the party wall is affected you serve notice on your neighbour.
Anywhere in the area, and there is no minimum job size. Open-plan conversion enquiries reach GS Renovation from across Havering and East London, and each gets a free survey at the RM1 property and a written quotation afterwards. Building control is coordinated with Havering Council where the work requires it. Email info@gsrenovationltd.co.uk to get started. Nothing is owed whether you proceed or not. Small jobs at an RM1 address are just as welcome here.
