Not every layout change needs a whole wall out. Widening a cramped doorway, adding a second door into a room or forming a wide opening between hall and living room can change how a home flows while keeping most of the wall, along with its storage space and furniture positions.

What to expect

  • 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.
  • 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.
  • 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.
  • 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.
  • In hallways, a new or wider opening into the living room can affect the protected route from the stairs to the front door. Building control may require fire doors, smoke alarms or other measures, especially in houses with three or more storeys.

From survey to sign-off in Derby

  1. Survey in Derby

    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 Derby City Council, 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.

Building control and neighbours in Derby

Structural openings in English homes need building regulations approval before work starts. Derby City Council can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Wider doorways & openings in Derby: your questions

Can you work on older or listed homes in Derby?

Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.

Do I need building regulations to widen an internal door?

Only if the wall is load-bearing or the change affects fire safety, such as the escape route from upstairs. Widening an opening in a non-structural stud partition usually does not need structural approval. We confirm which applies at the survey, and handle the building control application or notice where it is needed.

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 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.
