Open-plan kitchen, diner and living conversions in Radlett. Trusted, professional, 30+ years' hands-on experience.
Open plan in Radlett means working with detached and semi detached houses where the wall between kitchen and dining room is carrying the floor above. We appoint the structural engineer, remove the wall, install the beam and coordinate the building control inspections, then make good so the room reads as one space.

Detached houses, and the survey has put a number on them. The 2015 buildings survey carried out for the Radlett neighbourhood plan recorded 1,465 detached units, 55.5 per cent of the stock, with a further 74 large detached units at 2.8 per cent. A detached house gives you windows on both flanks, so once the internal wall goes the light travels the full depth of the plan rather than stopping halfway.
The same survey recorded 634 semi detached units at 24 per cent and 295 terraced units at 11.2 per cent. There the beam has to land on the wall you share with next door, which sets the bearing detail. The Radlett (North) Conservation Area Appraisal also notes two pairs of much altered inter war semi detached houses on the south east side of Upper Station Road. Where a house has already been altered, we open up and check the structure before a layout is agreed.
The two are one project as far as the build is concerned, and the extension side carries the planning question. Hertsmere Borough Council states that rear and side extensions to the Radlett bungalows covered by the Article 4 Directions can still be carried out without a planning application, subject to the relevant permitted development legislation. Permitted development is a set of conditions rather than a blanket yes, so we establish the position for your address before any layout is drawn.
Applications go to Hertsmere Borough Council, whose planning strategy team is based at the Civic Offices, Elstree Way, Borehamwood WD6 1WA. Sequencing is what keeps the job moving. The engineer's calculations are needed before the beam can be ordered, the beam has to be seated before the old wall can come out fully, and the bearings have to be inspected before they are covered. We set that order at survey and price to it.
Radlett has its own made neighbourhood plan, The Radlett Plan 2020 to 2036. Aldenham Parish Council is the qualifying body and set up a local steering group to prepare it. The plan passed its referendum on 6 May 2021 and was made, and it is used alongside the borough Local Plan to decide planning applications in the village. Taking out an internal wall does not engage either document. Anything that changes the outside of the house does, which is why we separate the internal and external parts of an open plan scheme when we scope it.
An open plan scheme in Radlett is decided by the house you already have, so that is where we start. The survey establishes which walls carry load, what the beam can bear onto, and where the services and the flue run before a single layout is proposed. Structural work and finishing are carried by the same team, so the ceiling line, the floor level and the plaster meet properly where the wall used to be. We are fully insured, building control is coordinated for you, and quotations are free and carry no obligation.

FAQ
As accurate as the information behind it. An open-plan conversion figure given over the phone for a Radlett home will move; one written after we have looked carefully at the WD7 property usually does not. GS Renovation allows for the making good that 1930s and interwar construction demands, and shows the Hertsmere Borough Council element separately. That is why our Radlett quotations tend to hold. Ring 07472 424 226 to book the free survey at your WD7 address. 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.
Yes, and it is the part of an open plan scheme worth settling first. Building control checks fire protection and means of escape in case of fire, and a stair discharging into an open kitchen no longer has a protected route to the front door. The answer is worked out at design stage, through interlinked detection, a fire resisting enclosure elsewhere, or escape windows. Agreeing it early is what keeps the layout you want.
That is set by where the beam can bear. A short nib of the old wall, or a pier rebuilt in engineering brick under a padstone, gives the steel a bearing the existing masonry may not offer. Where you want a clear opening from one flank wall to the other, the alternative is a column at each end taken down to its own foundation. On older houses here the foundations can be shallow, so that is designed, not assumed.
It can, though the garage floor, walls and foundations were built to a lower standard than the house. The slab is checked for depth and damp proofing, the front opening is closed with a wall carrying its own foundation, and insulation is brought up to current standards. The work is inspected by Hertfordshire Building Control alongside the wall removal inside. Where the garage roof ties into the house, that junction is opened up before a layout is agreed.
It can be, and the drainage decides it rather than the floor. Radlett sits in the valley of Tykes Water, with the village centre and station in a narrow valley rising from about 200 feet to 400 feet, and split level ground floors follow that fall. Raising the lower room means checking headroom under the new beam and the fall on existing waste runs. Dropping the higher room means excavating beside foundations the engineer has to assess.
