About our wider doorways & openings service in Buckinghamshire

Wider doorways and openings are gaps formed or enlarged in internal walls, with a lintel or steel beam carrying the masonry and loads above. They sit between a simple door change and a full wall removal: the span is shorter, but each opening still needs the right support and approval if the wall is structural.

From the first survey visit to the completion certificate, we take care of wider doorways & openings across Buckinghamshire. Towns we cover include Amersham, Chalfont St Peter and Aylesbury, among other places in the area. The engineer sizes the steel, we deal with building control, and our team fits and packs the beam before making good.

Worth knowing before you start

  • Openings are cut with a masonry saw where possible rather than broken out with a hammer. Clean cuts keep the brickwork either side sound, give a straighter edge for plastering and send less vibration through the rest of the wall.
  • Each side of the new opening needs enough solid wall for the lintel or beam to sit on. If the opening runs close to a corner, another doorway or a chimney breast, there may not be enough masonry, and a column or padstone may be required.
  • When an opening widens, the old threshold strip and floor finishes often stop short. Carpet, boards or tiles need joining neatly across the new width, and a change in floor height between rooms may need a threshold bar or a gentle ramp.
  • Older door surrounds and walls can hide asbestos in textured coatings, insulating board above doors or panelling. In buildings built before 2000 it must be identified before the wall is cut, so a refurbishment survey of the area is arranged where there is a risk.
  • Forming or widening an opening in a load-bearing wall is building work needing building regulations approval in England and Wales. In Scotland a building warrant is required before work starts, and in Northern Ireland an application is made to the council's building control.

Four stages, one team

  1. Survey in Buckinghamshire

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

    We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Buckinghamshire

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either the local council's building control team or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Wider doorways & openings in Buckinghamshire: your questions

Who approves wider doorways & openings in Buckinghamshire?

Structural work in Buckinghamshire needs a building notice or full plans application to the local council's building control team or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.

Can I stay at home while the work is done in Buckinghamshire?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

How long does it take to widen a doorway?

The structural part usually takes one to two working days: propping, cutting the opening, fitting the lintel or beam and packing it. Plastering follows, then a few days of drying before linings are painted or a new door is hung. Building control inspection fits in once the support is in place.

What if there is a radiator or switch where the new opening goes?

It gets moved before the opening is cut. Radiators and pipework are relocated by a heating engineer, and switches and sockets by an electrician, with notifiable electrical work in England meeting Part P. These items are priced separately in the quote, so you can see what each one adds.

Can I widen a doorway in a load-bearing wall?

Yes. The extra width is spanned by a lintel or steel beam that a structural engineer specifies, sitting on solid bearings either side. Because the wall is structural, the work needs building control approval in England and Wales, a building warrant in Scotland, or a council building control application in Northern Ireland. We arrange the design and approval.

Will widening a doorway make a mess?

There is some dust and noise, mainly on the day the opening is cut. We screen the area, protect floors along the route and use dust extraction on saws where possible. Rooms either side are affected for a day or two, while the rest of the house stays in normal use.
