Load-Bearing Wall Removal Morden

GS Renovation removes load-bearing walls throughout Morden, from the interwar terraces of the St Helier estate and the streets off London Road to the 1930s semis near Morden Hall Park. We open up these houses safely and leave the floors above properly carried.

In Morden, a complete single opening typically costs £2,500 to £6,500 or more, including the engineer's calculations, the steel beam, propping and making good (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Morden.

How the job runs

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

Load-bearing walls in Morden's 1930s houses

Morden's interwar terraces and semis were built with a load-bearing brick wall between the front and rear reception rooms, carrying the first-floor joists and often a section of the roof. When homeowners in SM4 want to combine those two rooms, that wall is almost always structural, so we never rely on guesswork. A structural engineer inspects the property and calculates the exact steel beam needed for the span.

The RSJ is sized to the load, then set to bear onto concrete padstones spread across the original brickwork. Before any masonry comes down we install temporary props such as Acrows and strongboys, take the wall out in controlled stages, and lower the beam into place. In a Morden house the work stays within the two rooms being joined, so the rest of the house stays in use.

Housing in Morden

Morden has around 9,990 homes on the Council Tax list: 17% post-war, 81% interwar and 2% predate 1919, with 25% flats and 75% houses. 64% of homes here are terraced; the spine wall of a terrace in Morden often ends in the party wall, where the new beam lands.

Merton's four stages for a Morden wall removal

81% of Morden's homes were built between 1919 and 1939. In a house of that age, taking out the wall between the front and back reception rooms feels like one job on site. Merton splits it into four notification stages: commencement, inspection of structural works, fire proofing and completion. The structural inspection needs the beam, padstones and packing visible, so the ceiling repairs on each side wait for it. The fire proofing stage needs the boarding or coating on the steel checked before any skim. Planning the plasterer's two visits around those stages keeps the Morden room out of use for the shortest time.

The charge depends on how the job is described. Merton charges a set fee for the standalone removal of an internal wall in a single-dwelling domestic building. That fits a straightforward knock-through in a Morden house. If the design grows to take in the chimney breast, the kitchen wall or a wider rear opening as well, describe it that way on the application from the start. A house that has been altered before can turn up a second wall that needs work once the plaster is off, so allow for it in the survey rather than on site.

Party wall duties and building control in SM4

Because most Morden houses are terraced, with some semis, the beam frequently needs to bear near or into the shared party wall with the neighbouring property. Where that happens the Party Wall Act applies, and you, as building owner, serve notice on the adjoining owner before the steel goes in; we give you the drawings and programme it needs. Getting this right early keeps the neighbours on side and avoids any hold-ups once the props are already loaded.

This is internal structural work, so it falls under the Building Regulations rather than planning permission. Merton Council's building control inspects the propping, the padstones and the seated beam, then issues sign-off once the fire protection and packing are complete. We arrange the inspections, keep the paperwork in order, and hand you building control's completion certificate, which will satisfy any future buyer's surveyor in SM4.

• Steel boxed, fire protected and finished ready for decoration
