How the job runs

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

In Streatham's bay-fronted terraces the spine wall running front to back usually carries the floor joists and the wall above, and the thickened wall between the kitchen and the rear closet wing often does too. Because these homes were built room by room, you cannot assume a wall is a simple partition. Every job here starts with a structural engineer establishing exactly what the wall supports before anyone lifts a hammer.

The engineer then sizes a steel beam to replace the wall, and we cast or supply padstones for each bearing end so the load is spread into sound masonry. We install temporary props to hold the floors above, break the wall out in careful stages, lift the steel into place onto its padstones, then transfer the load and strike the props. Nothing is rushed and nothing is left guessed.

Housing in Streatham

Streatham has about 27,640 homes on the Council Tax list: 43% pre-1919, 27% interwar and 29% post-war, with flats making up 67% and houses 33%. Where most homes are flats, taking out a wall in a flat in Streatham can affect the floors above, so the freeholder's licence comes first and the engineer we appoint checks what it carries.

Removing a wall in a Streatham conversion flat, and who is upstairs

67% of homes in Streatham are flats and 33% are houses. Where your flat is the ground floor of a converted house, the wall you want to remove may carry the walls and floor of the flat above, and the temporary works can reach into that home too. The propping may need holes through the wall just above your ceiling line, which can open into the upstairs flat, or it may be done with props set entirely in your rooms. Which method the structural engineer we appoint chooses decides whether you need the upstairs owner's access and agreement, so ask that question at design stage.

Lambeth advises sending in a full plans application no less than five weeks ahead of the planned start on site. For a Streatham flat those weeks are not wasted. It is when the freeholder's licence to alter is negotiated, the upstairs owner agrees access, and the steel is detailed to fit up a shared staircase. Lambeth accepts a building notice or a full plans application for this work, and in a building shared with other leaseholders the full plans route gives everyone the same approved drawing to refer to.

Building control sign-off across SW16

Taking out a load-bearing wall is a Building Regulations matter, not a planning one, so no planning permission is needed for this internal work unless the house is listed, when listed building consent is needed for internal works too. Lambeth Council's building control, or a registered building control approver, checks the engineer's calculations and inspects the beam, its bearings and the propping before sign-off. We book the inspections, meet the inspector on site and hand you the completion certificate you will want when you sell.

Where the wall being removed is the party wall shared with the house next door, or where the new beam bears into it, the Party Wall Act applies and you serve notice on your neighbour as building owner, or your surveyor does, before work begins. In Streatham's tightly packed terraces this comes up often, so we flag it early, give you the engineer's drawings and the programme the notice needs, and build to any award to keep the job moving.

Working off a busy main road

The terraces closest to Streatham High Road sit on or just off a main bus route, and that changes how a wall removal is serviced. There is nowhere to stand a lorry on the High Road itself, so steel is delivered into a side street and carried the last stretch by hand, which means the beam length and the walk in are both checked carefully before anything is ordered from the fabricator.

On the residential streets further out the picture is easier. Most have permit parking that Lambeth will suspend for a skip or a delivery given enough notice, and many houses have a front garden with a path wide enough to barrow along. Rubble volume is the thing owners underestimate, since a full spine wall in an SW16 terrace fills more than one skip, so collections are staged rather than left to pile up. Materials are stored inside where possible, since a front garden full of steel and blocks tends to attract attention overnight.

FAQ

Frequently Asked Questions about Load-Bearing Wall Removal Streatham

What does the load-bearing wall removal quotation for a Streatham home cover?

A Streatham quotation for load-bearing wall removal sets out scope, programme and price on one document, within £2,500 to £6,500 or more per opening (indicative). It shows what is done, in what order and at what cost, and the order is not arbitrary: the engineer confirms what the wall carries before anything is priced. Exclusions are stated plainly rather than left to be discovered once work starts at the SW16 property.

What complicates wall removal in a Streatham house divided into flats?

The structure serves more than one home. In your Streatham house converted into flats, a wall on the ground floor may be carrying floors that belong to other dwellings, and the work affects people who are not the client. The engineer designs for the loads actually present rather than for a single house, and the freeholder's consent is required alongside building control approval.

Can a wall be removed in a ground floor Streatham flat?

Often, with the flats above properly supported throughout. In your Streatham conversion the wall being removed may carry every storey above it, so the temporary works have to hold up other people's homes while the beam goes in. That design is the critical stage. Residents above are told what is happening and when, because the propping period is noisy and unavoidable.

How are the flats above protected during work in Streatham?

By propping to the engineer's design and by keeping the disruptive period short. At a Streatham property the props and needles supporting the upper floors bear onto something capable of taking that load, which may mean continuing the support to a solid floor below. The sequence of masonry removal is specified. Nothing is improvised where other households are living above the work.

Do the other leaseholders in a Streatham building have a say?

Not usually a veto, though they are affected and often consulted. In a Streatham conversion the freeholder grants the licence, but the other flats live with the noise, the shared entrance and any disturbance to the structure between them. Where the lease requires it their consent may be needed. Telling them what is planned before work starts prevents most of the objections that arise.

What does the lease say about alterations in a Streatham flat?

Usually that structural alteration is reserved to the freeholder and needs written consent. For a Streatham conversion the lease also frequently regulates working hours, floor finishes and use of the common parts. Reading it before commissioning a design avoids a scheme that the building will never permit. Where consent is available it comes with conditions, and those conditions are part of the works.

When does removing a wall in a Streatham terraced house involve the Party Wall Act?

Only where the work touches a party wall. 21% of Streatham homes are terraced houses, and in one of those at least one end of the new beam may bear into a wall shared with the house next door. Cutting a pocket for that bearing is work the Act covers, so you as building owner serve notice on the neighbour. A wall removed with both bearings on walls wholly inside your own house does not need a notice.

Is a wall in a Streatham flat built since 2000 likely to be load-bearing?

Only the drawings can tell you. 10% of Streatham homes were built in 2000 or later, and a newer block may use a concrete frame, where internal walls are lightweight partitions, or a system in which walls between rooms carry the floor above. We ask the managing agent for the structural drawings first. A partition may come out with no steel at all, while a structural wall in a newer block may be ruled out entirely.

Can an internal wall come out of a listed house in Streatham?

Only with listed building consent as well as building control approval. Lambeth Council states that Lambeth has over 2,000 statutory listed buildings, so check the national list for your address before assuming a wall is a building regulations matter only. Listing covers the interior, and an original internal wall is part of what is protected. The consent application needs a heritage case for the change, which takes longer to prepare than the structural design.
