Planning wider doorways & openings in Hanworth
Our wider doorways & openings service in Hanworth covers everything from the first visit to the completion paperwork. Our coverage runs across London, so nearby villages are included too. Postcode districts we cover here include TW1, TW2, TW3, TW4 and TW11.
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.
- 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.
- 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.
- 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.
- 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.
Four stages, one team
Free visit
A short visit to Hanworth 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 the local council's building control team, 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.

Building control and neighbours in Hanworth
For Hanworth, 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.
Questions about wider doorways & openings in Hanworth
Do you cover Hanworth for wider doorways & openings?
Yes. We carry out wider doorways & openings in Hanworth and the TW1, TW2, TW3, TW4 and TW11 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do I need a party wall agreement for wider doorways & openings in Hanworth?
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 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 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.
