Planning wider doorways & openings in Southampton
Need wider doorways & openings in Southampton? Our coverage runs across Hampshire, so nearby villages are included too. We survey the property, arrange the engineer's design, deal with Southampton City Council, fit the steel and make good, all under one quote for SO14, SO15, SO16, SO17 and SO18 addresses.
We arrange a survey visit, structural calculations where the wall is load-bearing, building control, propping, the lintel or beam, new door linings if you want them, and making good. One itemised written quote covers the lot, and the price is fixed in writing once the opening size and finish are agreed.
Worth knowing before you start
- 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.
- 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.
- 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.
How the job runs in Southampton
Free visit
A short visit to Southampton to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to Southampton City Council, so approval is in place before the wall is touched.
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.
How much should I budget in Southampton?
As a guide, budget £1,100–£2,800 including VAT for widening an internal doorway in Southampton, based on published UK cost guides adjusted for prices in the South East (+12%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Widening an internal doorway | £1,100–£2,800 | Opening widened with a new lintel or short beam, approval where structural, and making good |
| Plastering and making good | £340–£1,340 | Boxing the beam, bead and skim, reveals, floor infill where the wall stood and tidy-up |
| Load-bearing wall removal with steel beam | £2,250–£5,600 | Typical internal wall up to about 4 m: calculations, building control, propping, steel, padstones, fitting, fire protection and making good |
| Structural calculations for a beam | £280–£840 | Site measure or photos, beam and padstone design and calculations for building control |
Figures include our approximate regional adjustment for prices in the South East (+12%) and are rounded. How these figures are worked out.
Building control and neighbours in Southampton
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 Southampton City Council 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.
Local questions answered
What happens at the survey visit in Southampton?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
How much do wider doorways & openings cost in Southampton?
As a guide, budget £1,100–£2,800 including VAT for widening an internal doorway in Southampton, based on published UK cost guides adjusted for prices in the South East (+12%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
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.
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.
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.
