Builders in Battersea, SW11

Side returns, loft conversions and full renovations across SW11, from Between the Commons to the riverside.

Battersea, Wandsworth

The most extended postcode in south west London


SW11, and particularly the grid Between the Commons, has been extended and converted more comprehensively than almost anywhere else in London. That has an upside: the precedent is established, the council knows the applications and the neighbours have usually been through it themselves.

It also means that when you buy here you often inherit somebody else's building work, and not all of it was done well. A significant share of what we do in Battersea is putting right an extension or conversion carried out badly a decade ago.

Local knowledge

What building in Battersea actually involves

Established local precedent

So many side returns and dormers have been approved across SW11 that the design and consent route is well trodden. Wandsworth Council deals with a high volume of these applications and the outcomes are relatively predictable.

Inherited building work

Much of the stock has already been altered. We regularly find uncertified steels, extensions built without building control sign off and flat roofs that were never detailed properly. It matters when you sell, so it is worth knowing what you have.

Shaftesbury Park and other designations

The Shaftesbury Park Estate and several other pockets of SW11 carry conservation area designation, which restricts elevations, roof alterations and windows. Much of the surrounding terracing is not designated.

What we build in Battersea

The standard SW11 project is the same combination that works across the Victorian terraces of south west London: a side return infill to widen the kitchen, and a rear or L shaped dormer to add a bedroom and ensuite in the roof.

Alongside that, a large part of our Battersea workload is remedial. Correcting an extension that leaks at the junction with the original roof, replacing a flat roof that was never falls correctly, or regularising work that was done without building control approval and is now blocking a sale.

Between the Commons

The grid between Clapham Common and Wandsworth Common, sometimes called the Toast Rack because of the parallel street pattern, is the heart of family Battersea. The houses are consistent Victorian terraces with back additions, and almost every one of them is a candidate for the same alterations.

The density is the constraint. Frontages are narrow, parking is controlled, and on most streets there is no scope for a skip outside the door without a permit and a bay suspension. We arrange those in advance and sequence deliveries so vehicles are not sitting on the road.

Buying a house with existing building work

If you are buying in SW11 and the house has already been extended or converted, the questions worth asking are whether building control signed it off, whether the structural calculations exist and whether a party wall award was made.

Missing paperwork is common and it is not always fatal. Regularisation is possible in many cases, and indemnity insurance covers some situations. What you do not want is to discover the gap at the point you are trying to sell. We are happy to look at what you have and tell you where you stand.

Flat roofs, and why so many fail here

Every side return and rear extension in Battersea has a flat or near flat roof over part of it, and flat roofs are where most of the remedial work we do originates.

The failures are consistent: insufficient fall so water sits rather than runs, a poorly detailed upstand where the new roof meets the original rear wall, and inadequate flashing at the junction with the neighbouring property. We build falls properly, detail the upstands correctly and use systems appropriate to the pitch, because the cost of getting it wrong is the whole ceiling below.

We inherited an extension that leaked every winter. NSPEC diagnosed it as a fall and upstand problem rather than the membrane, rebuilt it properly and it has been dry ever since. They were straight with us about what was wrong and what it would cost.

Questions

Building in Battersea: common questions

Our extension leaks. Can you fix it rather than rebuild it?

Often yes, and diagnosis comes first. Most leaking flat roofs in SW11 fail because of inadequate fall or a badly detailed upstand rather than the membrane itself, and patching the membrane on a roof that ponds water simply moves the failure. We will tell you honestly whether it is a repair or a rebuild.

What if previous work has no building control sign off?

It is common in SW11 and it is usually solvable. Depending on the age and nature of the work, regularisation through the council may be possible, or indemnity insurance may be appropriate. It is worth resolving before you market the property rather than during a sale.

Do you need permission for a side return here?

Many fall under permitted development if the depth, height and materials stay within the limits and rights have not been removed. The Shaftesbury Park Estate and other designated pockets change that, and flats have no permitted development rights. We check your address before quoting.

Which parts of Battersea do you cover?

All of SW11: Between the Commons, Clapham Junction, Battersea Park, Battersea Rise, Lavender Hill, Queenstown Road and the riverside. We also cover neighbouring Wandsworth, Clapham, Chelsea and Fulham.
