Planning wider doorways & openings in Devon

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.

Looking for wider doorways & openings in Devon? That includes Bideford, Exmouth and Tiverton, plus smaller towns and villages nearby. Our teams handle the calculations, the building control approval, the propping and the steel itself, and leave the opening ready for plastering and decoration.

Key points for your project

  • For a modest increase in width, a lintel may be all that is needed, while a wider opening carrying a floor or wall usually needs steel. The engineer chooses the type and size from the actual loads, never from the opening width alone.
  • Light switches, sockets and cables often sit right beside a doorway. These are moved before cutting, and any electrical alterations in England must comply with Part P of the building regulations where they are notifiable.
  • In older houses, a doorway may already have a timber lintel that has rotted or a brick arch that is hard to extend. These are replaced rather than added to, and the engineer allows for soft lime mortar and any cracking found once the wall is opened.
  • Standard internal doors come in set widths, so it makes sense to size the opening to suit an off-the-shelf door and lining. Odd sizes need made-to-measure doors and linings, which take longer to arrange.
  • 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.

How the job runs in Devon

  1. Survey in Devon

    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.

How much should I budget in Devon?

As a guide, budget £1,050–£2,600 including VAT for widening an internal doorway in Devon, based on published UK cost guides adjusted for prices in the South West (+3%).

Building control and neighbours in Devon

For Devon, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.

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.

Questions about wider doorways & openings in Devon

How soon can wider doorways & openings start in Devon?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.

Which towns in Devon do you cover?

We cover towns including Plymouth, Exeter, Paignton and Torquay, plus the villages and smaller towns around them.

How wide can I make a doorway?

That depends on the wall, what it carries and how much solid wall is left at each side for the support to bear on, and a structural engineer sets the limit. Many people go from a single door to a double-width opening, and beyond that the job starts to become a partial wall removal.

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.

What is included in the price for a wider doorway?

The itemised written quote lists the survey, any engineer's calculations and building control fees, propping, cutting the opening, the lintel or steel, linings or plastered reveals, and making good. Moving services, supplying doors and flooring joins appear as separate lines. The price is fixed in writing once the size and finish are agreed.

Who approves wider doorways & openings in Devon?

Structural work in Devon 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.
