How the job runs
- Free site survey at your New Malden address and an itemised quote.
- The engineer we appoint sizes the beam, and the work is registered with Kingston Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- The floor above is propped, the wall comes out and the beam is set on padstones.
- Building control inspects the steel before it is covered. We make good, and the completion certificate follows.

Load-bearing walls in New Malden's interwar semis
The typical New Malden semi was built in the 1930s with a brick cross wall between the front and back rooms, carrying floor joists and often a stretch of first-floor masonry above. Homeowners frequently want the back reception knocked into the front room or the kitchen, but that wall is usually load-bearing, so we never touch it until a structural engineer has confirmed exactly what sits on top.
The engineer we appoint sizes a steel beam to carry the load once the wall comes out. The beam bears onto padstones at each end, spreading the weight into the remaining brickwork or a new pier. We install temporary props, take the wall down in controlled stages, lift the steel into position and only then remove the propping, so the structure is supported at every moment.
Housing in New Malden
Count the homes in New Malden and you get about 7,070: 34% built since 1945, 33% between the wars and 33% before 1919, with flats at 31% and houses at 69%. Only the beam end on the shared wall of a semi in New Malden needs a party wall notice, and 31% of homes here are semi-detached.
Kingston's own fee line for a New Malden load-bearing opening
Kingston's building control charges list removal or formation of an opening in a load-bearing wall as a separate item, with the same charge under full plans or building notice. The regularisation charge for the same work is half as much again. In New Malden that line matters as much when buying as when building. If the house you are buying already has its reception rooms knocked together, ask the seller for the completion certificate for that opening. Without one, the council's route to put it right is a regularisation application, and the officer may need plaster cut away at each end of the beam to see the bearings and the steel before anything is certified.
Because Kingston charges the same on either route, the choice for a New Malden wall comes down to certainty and timing. Under full plans Kingston has up to 5 weeks to approve, extended to 8 weeks if revisions or more information are needed. A building notice lets work begin within 48 hours of submission, but nothing is approved in advance. For a plain opening between two reception rooms with the calculations already done, the quicker route can suit. Where the beam also picks up a chimney breast or a length of wall above, approved drawings before the steel is cut are worth the wait.
Building control sign-off across KT3
Removing a load-bearing wall inside a New Malden house is a building regulations matter, not a planning one. You do not need planning permission for this internal work; instead the engineer's calculations go to Kingston Council building control, who inspect the propping, padstones and finished steel before issuing completion. We book those inspections and hand you the certificate at the end.
Because these are semi-detached houses, one flank of the property shares a party wall with next door. Where a new beam bears into that shared wall, the Party Wall Act applies and you, as building owner, serve notice on the adjoining owner. We identify that early, give you the drawings and programme the notice needs and keep the neighbour informed so the job runs without disputes or delays.
How wide the opening should really be
A full-width opening is not automatically the best answer in an interwar semi. The wider the span, the deeper the beam, and a deep downstand in a room with a standard 1930s ceiling height eats into the sense of space it was meant to create. There is also a practical loss: two rooms have four usable walls between them, and one long room has considerably fewer places to put a sofa, a television or a dresser.
Leaving a short return of masonry at each end often gives a better room. It shortens the span, keeps the beam shallower, provides somewhere for a radiator or a switch, and preserves a little separation between the two ends of the space. We mark out different widths on the floor with tape before anything is instructed, so you can stand in the room and see the difference rather than judging it from a drawing.

FAQ
Frequently Asked Questions about Load-Bearing Wall Removal New Malden
What does the load-bearing wall removal quotation for a New Malden home cover?
Labour, materials, approvals, reinstatement and the programme are all on the load-bearing wall removal quotation for a KT3 home in New Malden, inside £2,500 to £6,500 or more per opening (indicative). GS Renovation writes it so each element can be checked against another builder's round number. The scope reflects the property, because whatever sits over the New Malden wall decides the beam.

Can I remove the wall between the two reception rooms in my 1930s New Malden semi?
Usually yes, but that wall is often load-bearing, carrying joists and masonry above. A structural engineer must assess it first and size a steel beam on padstones to replace its support. The work is signed off by Kingston Council building control, and if the beam bears into the shared party wall, you serve party wall notice too.
Where does each end of the beam land when a New Malden semi loses its cross wall?
Usually one end sits in the party wall shared with the attached house and the other in the outside flank wall. That asymmetry matters: the party wall end needs a party structure notice at least two months ahead, while the flank end carries no notice duty but may need a deeper padstone if the old brick is soft. The engineer fixes both bearings before any steel is ordered.
Which step comes first when a structural wall is coming out of my New Malden house?
Paperwork, then props. The engineer's design is drawn first, because building control needs the calculations and the neighbour's notice needs the drawings. Next the neighbour has time to reply: consent lets work proceed, dissent brings in surveyors and an award. Only after that are Acrow props and strongboys set under the floor above and the masonry taken out in short lifts.
Does a chimney breast above the wall complicate removing it in my New Malden house?
It can. In interwar semis the wall between the receptions sometimes also carries part of the breast upstairs, so the steel may take a heavy point load as well as the floor. The engineer sizes for that, or the upper breast is removed and supported separately first. Finding it mid-demolition is how programmes slip, so the bedroom and loft are inspected at survey.
What changes if my New Malden home is a flat rather than a semi?
The lease comes first. VOA counts 31% of New Malden dwellings as flats, and a lease usually makes structural work conditional on the freeholder's written consent. Opening a flat's hallway into its living room also alters the escape route, so building control needs an agreed fire strategy alongside the beam calculations. How the steel travels up a communal stair is worked out before it is ordered.
Can a New Malden wall removal start within 48 hours of the building notice going in?
Kingston allows building work to start within 48 hours of a building notice being submitted, so the application itself need not hold the job up. What usually does is everything around it. The structural engineer we appoint has to size the beam, the steel has to be made to that size, and if a bearing goes into the party wall, the notice you serve on your neighbour has its own period to run. Submit the building notice once those are settled, not before.
What happens if a wall comes out of a listed house in New Malden without consent?
Kingston says it is a criminal offence to carry out works to a listed building which require listed building consent. Listing covers the inside of a building as well as the outside, so taking out an internal wall can need consent even though an unlisted house would need no planning permission for it. Check the listing before any design work starts. If the house is listed, no wall comes down until that consent is granted, whatever building control has approved.
Can an upstairs partition affect removing a wall in a New Malden house built before 1919?
It can. 33% of homes in New Malden were built before 1919. In a house of that age a first floor partition of timber studs can carry part of the floor or roof and stand directly over the ground floor wall you want to remove. The structural engineer we appoint looks at the room above as closely as the wall itself. Where a stud wall bears on that line, the beam is sized to take its load too.
