About our wider doorways & openings service in Conwy
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.
Across Conwy, wider doorways & openings usually come up when people want more light, a better layout or a way through to a new extension. Towns we cover include Colwyn Bay, Llandudno and Abergele, among other places in the area. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Key points for your project
- 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.
- 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.
- 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.
- Widening a single doorway in a load-bearing wall usually takes one to two days for the structural work. The plaster then needs time to dry before the door linings are decorated or a new door is hung.

Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building rules for Conwy
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Conwy County Borough Council handles building control for Conwy. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.
Wider doorways & openings by town
Wider doorways & openings in Conwy: your questions
Which towns in Conwy do you cover?
We cover towns including Colwyn Bay, Llandudno and Abergele, plus the villages and smaller towns around them.
Do you cover Conwy for wider doorways & openings?
Yes. We carry out wider doorways & openings in Conwy. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Can a doorway be widened for wheelchair access?
Yes, and it is one of the most practical home adaptations. The opening is sized for the clear width needed, allowing for the door, lining and door stops. If a council grant or occupational therapist is involved, share their requirements with us so the opening is designed to meet them first time.
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.
Is a lintel or a steel beam needed for a wider door?
It depends on the loads. A lintel can be enough for a modest widening under light loads, while an opening carrying floor joists or a wall above usually needs steel. The engineer decides from the actual loads and span rather than the width alone, and we fit whichever is specified.
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.
Can you work on older or listed homes in Conwy?
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.
