Open-Plan Conversions Radlett

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.

For Radlett, on London-derived ranges a knock-through finished as one room typically costs £3,000 to £8,000 or more, including the steel beam; Hertfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Radlett: the structural engineer we appoint designs the steel, we install it, and building control signs it off.

How the job runs

1. Free site survey at your Radlett address, covering the walls, services and floor levels, and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Hertfordshire Building Control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props in, opening cut, beam on padstones; then floors, heating and electrics are joined up.
4. Building control inspects the steel before it is covered. We finish the room, and the completion certificate follows.

The houses in Radlett that open up well

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. Those figures count buildings in 2015, while the valuation list figures on this page count dwellings in 2025, each flat separately. 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.

Housing in Radlett

Around 3,500 homes make up Radlett on the valuation list; 24% are flats and 76% houses, and 12% date from before 1919, 19% from between the wars and 67% from after 1945. 47% of homes here are detached; a detached house in Radlett allows wider openings with no party wall notice.

Opening up and extending in the same job

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.

The Radlett Plan sits alongside the borough Local Plan

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.

• Utility and boot room space carved out of the new layout
• Making good, plastering and decorating the finished space
• Rooflights and glazed roofs to bring light deep into the plan
