Planning wider doorways & openings in New Malden

For homes in New Malden and the KT1, KT2, KT3, KT4 and KT5 districts, we handle wider doorways & openings from survey to sign-off. Our coverage runs across London, so nearby villages are included too. The beam is sized by a structural engineer and inspected before it is boxed in.

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.

Things to plan for

  • When an opening widens, the old threshold strip and floor finishes often stop short. Carpet, boards or tiles need joining neatly across the new width, and a change in floor height between rooms may need a threshold bar or a gentle ramp.
  • 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.
  • 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.
  • 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.
  • 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.

    A short visit to New Malden to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  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.

Building control and neighbours in New Malden

For New Malden, 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.

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.

Local questions answered

Who approves wider doorways & openings in New Malden?

Structural work in New Malden 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.

Do you also work near New Malden?

Yes. We also cover nearby towns including Surbiton, Morden, Wimbledon and Ewell.

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 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.

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.

How much do wider doorways & openings cost in New Malden?

As a guide, budget £1,300–£3,200 including VAT for widening an internal doorway in New Malden, based on published UK cost guides adjusted for London prices (+28%). 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.
