An open plan conversion is three jobs in one: a structural opening, then the services that were buried in the wall, then the finishes across a room that is now a single space. The structural part sets the programme. We appoint the structural engineer, build to the calculations issued, and run the trades that follow on one sequence rather than three.
No Article 4 direction covers any part of Dunstable, so the work sits on the building regulations side
Central Bedfordshire Council has seven Article 4 directions in force, and none of them covers any part of Dunstable. An Article 4 direction is what withdraws permitted development rights, so householder rights here are not restricted by one. Planning consent can still be needed for other reasons, and a conservation area brings its own controls.
The building regulations side is not optional. A full plans application to Central Bedfordshire Council must include detailed plans, specifications and structural calculations, which is why the engineer comes before the demolition. We commission the calculations, submit the application, and book the inspections around the steel going in.
About 42 per cent of Dunstable's homes were built between 1945 and 1972
That is against about 26 per cent across England and Wales, on Valuation Office Agency council tax records. In the Dunstable South area the figure is about 61 per cent. Houses of that period were laid out with separate front and back rooms and a spine wall between them, and that spine wall is what an open plan scheme removes.
The spine wall is load bearing, and services can be buried inside it. A beam replaces the structure. The heating pipes, the sockets and the switches then have to go somewhere else, and the ceiling and floor levels either side may not match once the wall is out. We price the structure and the making good as one job.
40 per cent of Dunstable households live in a semi detached house
That is against 32 per cent across England and Wales at the 2021 Census. In the Dunstable East area, 1,890 of 2,688 households lived in a semi detached house, just over 70 per cent. A semi shares a party wall, and that changes an open plan scheme in two ways.
First, a beam bearing into the party wall makes your neighbour's structure part of the design and part of the notice. Second, sound from next door reads differently once two rooms become one, because there is no longer a closed door between the party wall and where you sit. Both are settled at design stage rather than after the plastering.
Two build periods in Dunstable produce two different open plan jobs
Council tax records count about 1,380 homes built between 1955 and 1964 in Dunstable East, and about 830 built between 1930 and 1939 in Dunstable West. A 1930s house has a hall, a front room and a back room, and the through lounge is formed by removing the wall between the two rooms and the chimney breast standing in it.
A house from the later period has thinner inner leaves and shallower foundations, so the bearing at each end of the beam is the question rather than the beam. The engineer sizes both from what the openings show. Where a chimney breast sits in the wall being removed, the stack above needs carrying too, which is a second structural decision inside the same job.
- Kitchen island services routed through the new floor
- Radiator relocation and underfloor heating in the new layout
- Open-plan kitchen-diner conversions
- Zoned lighting circuits and dimming for a multi-use room
- Beam depth checked against existing ceiling heights
Trusted Open-Plan Conversions in Dunstable
Open plan conversions go wrong at the handovers, not at the beam. We hold one programme across the engineer, the steel, the electrics, the heating, the plastering and the floor, so you end up with a finished room rather than a structurally open and unusable one. The structural calculations are always the engineer's, because we are a contractor and not an engineering practice, and we build to what is issued.
