Load-Bearing Wall Removal Hendon

GS Renovation removes load-bearing walls across Hendon, in the interwar semis on its residential roads towards Mill Hill and in the flats that make up most of NW4's homes. We open up these homes safely, prop as we go and install steel that building control signs off.

In Hendon, 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 Hendon.

How the job runs

1. Free site survey at your Hendon address and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Barnet 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.

Opening up Hendon's interwar semis

The 1930s semis on Hendon's residential roads were built with solid internal walls carrying the floors and roof above, so the wall between the front reception and the rear living room is frequently structural. Owners of those houses often want that spine wall taken out to create one long living space, and every removal starts with a structural engineer confirming exactly what the wall supports.

The engineer we appoint sizes a steel beam to carry the load, and we cast or supply padstones for the beam to bear onto at each end. On site we install temporary props, take the masonry down in controlled stages, lift the steel into position and transfer the load before anything is removed permanently. In a shared semi, one end of the beam often bears into the party wall with your neighbour.

Housing in Hendon

Around 16,060 homes make up Hendon on the valuation list; 62% are flats and 38% houses, and 20% date from before 1919, 37% from between the wars and 43% from after 1945. A wall in a flat in Hendon may carry the floors above, so the freeholder agrees first, which matters here because most homes are flats.

Removing a wall in a Hendon flat means visiting the flat below

62% of homes in Hendon are flats, and in a block the wall you want removed stands above someone else's home. When a load-bearing wall comes out of a flat, the beam gathers the load the wall spread along its length and delivers it at two points instead. Those points land on whatever is below, which is normally a wall inside the flat underneath. The structural engineer we appoint needs to see that wall, confirm it lines up with the new bearings and check it can take the concentrated load, so the first survey can include the neighbour's flat.

Temporary propping can reach down as well. If the floor of your flat cannot carry the props on its own, they run through to the floor below, which means working in someone else's home for part of the job. Ask the owner below for access in writing early, explain what will happen and when, and offer a condition record of their ceilings and walls before and after. In a Hendon block the managing agent may want to see that agreement before consent is issued. A neighbour who has been asked and kept informed is far easier to work alongside than one who finds props in the living room.

Building control sign-off across NW4

Taking out a load-bearing wall inside a Hendon home is governed by the Building Regulations, not planning permission, so Barnet Council's building control inspects and certifies the work. We arrange the notice, book the inspections at the right stages and make sure the beam, its bearings and any padstones are checked before the ceilings are closed up, giving you paperwork that stands up when you sell.

Where the beam bears onto the party wall shared with the adjoining semi, the Party Wall Act applies and you serve notice on your neighbour as building owner, or your surveyor does, before work begins. We coordinate the engineer's calculations and the building control application as one package, so you are not left chasing separate trades across a job that keeps your interwar house standing safely.

What makes one job longer than another

Two Hendon semis on the same road can produce very different programmes for what looks like the same opening. The first factor is what sits on the wall. A chimney breast standing on it adds a point load and often a second decision about whether the breast comes out too. The second is what is directly above: a bedroom floor is straightforward, a bathroom means isolating and re-running waste and supply pipes before anything is propped.

Access is the third. A house with a side passage and a driveway takes deliveries easily; a house where everything comes through the front door adds days of handling. Whether the floor is timber or a later concrete slab affects how the propping is founded and, for a goalpost, how the base pads are formed. We assess all of that at survey so the programme we give you reflects your house, not an average one.
