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.
Key points for your project
- 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.
- Hallway walls are often load-bearing because they line up with walls upstairs and carry the floor joists or the stairs. A wall that sounds hollow when knocked is usually a stud partition, but older homes can have timber walls that still carry loads, so the engineer checks.
- The main cost factors are whether the wall is structural, the width of the opening, what the support bears onto, how much electrical or heating work has to move, and whether you want new door linings and doors fitted as part of the job.
- Widening doorways is a frequent adaptation for wheelchair users and people using walking frames. Where a council grant or adaptation scheme is helping to pay, check its requirements for clear opening width before the opening is designed.
- 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.
What happens, step by step
Survey in Sutton
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.
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.
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.
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 rules for Sutton
Structural openings in English homes need building regulations approval before work starts. The local council's building control team 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.
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 Sutton: your questions
Do I need a party wall agreement for wider doorways & openings in Sutton?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
Do you also work near Sutton?
Yes. We also cover nearby towns including Carshalton, Banstead, Ewell and Wallington.
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.
Can I move a doorway to a different position?
Usually, yes. The old doorway is blocked up and a new opening is formed with the support the engineer specifies, and both changes are dealt with together for building control if the wall is structural. Moving a door can release wall space for furniture or a better kitchen or bedroom layout.
