Do you refurbish mansion flats in Battersea?

Yes. We redesign layouts, renew wiring and plumbing, add bathrooms and fit new kitchens, joinery and finishes in mansion flats and apartments, and we deal with the freeholder's consent and the managing agent's rules as part of the job.

Will my Battersea project need planning permission?

It depends on the property and the work. Many rear extensions and dormer lofts on houses are permitted development, but not in a conservation area, where a dormer needs planning permission, and not on a flat or maisonette. Most of Battersea is in Wandsworth, with some SW8 streets in Lambeth. We check your address and handle the application.

Do I need BSR approval to refurbish a flat in a tall block?

If the block counts as a higher risk building under the Building Safety Act, most work that would normally need building control, such as removing walls or moving a kitchen or bathroom, needs the Building Safety Regulator's approval before it starts, even inside a single flat. We prepare and manage those applications, and our guide to refurbishing a flat in a high rise building explains what is involved.

How much does a loft conversion cost in Battersea?

On typical London jobs priced on our estimator in October 2026, a rear dormer loft conversion came to £68,000 to £81,000 ex VAT. The figures are indicative. An L shaped dormer, an en suite or a higher specification changes the price, and the free estimate prices your own house in two minutes.

Builders in Battersea

MVV designs and builds kitchen extensions, loft conversions and full refurbishments in Battersea, across SW11 and the Battersea side of SW8. One team handles the design, the planning and the build, so you deal with one company from the first meeting to the final finishes. Battersea mixes well loved family terraces with red brick mansion blocks and new riverside apartments, and the work here is just as varied. A side return extension on a terrace between the commons, a complete refurbishment of a mansion flat near the park, or a new layout and finish for a modern apartment.

Battersea homes and what they need

Between Clapham Common and Wandsworth Common, the streets around Northcote Road are lined with Victorian terraces, most with a back addition, a side return and a loft that can be converted. Around Battersea Park and along Prince of Wales Drive are red brick mansion blocks, and the Shaftesbury Park Estate is a planned estate of small Victorian cottages. Closer to the river, around Nine Elms and Battersea Power Station, most homes are newer apartments.

Each asks for a different approach. A terrace usually wants more space at the back and in the roof. A mansion flat usually wants a better layout, new services and finishes that suit its period. A new apartment usually wants a fit out that feels less standard than the one it came with.

Extensions and lofts on Battersea terraces

Most terrace extensions here fill the side return, run across the back of the house, or wrap round as one kitchen and living room facing the garden. Our guides compare a rear extension or side return, set out wraparound extension ideas and show what a kitchen extension costs. In the roof, a rear dormer, or an L shaped dormer over the back addition, adds a bedroom and a bathroom: see Victorian loft conversions.

Our house extensions and loft conversions pages explain how we take each from survey to handover.

Refurbishing mansion flats and apartments

A mansion flat refurbishment is usually about the plan as much as the finish: opening a closed kitchen to the living room, adding a second bathroom, and replacing wiring and plumbing that may not have been touched in decades. Our guides to flat renovation costs in London and knocking through a wall cover the main decisions.

Work in a flat also involves the building. Most leases need the freeholder's written consent for alterations, and managing agents set rules on working hours, deliveries and the use of lifts and common parts. In taller blocks that count as higher risk buildings under the Building Safety Act, most work that would normally need building control needs approval from the Building Safety Regulator before it starts. We prepare those BSR applications ourselves, and our guide to refurbishing a flat in a high rise building explains the process.

Planning in Battersea

Battersea is in the London Borough of Wandsworth, so most applications here go to Wandsworth Council, although some SW8 streets fall under Lambeth. Both councils have conservation areas in the area, the Shaftesbury Park Estate among them, and inside a conservation area a dormer loft conversion is not permitted development and needs planning permission. Flats and maisonettes have no permitted development rights, so an extension to a flat always needs an application.

We check the position for your address early, prepare the drawings, and manage the application, along with any party wall agreements the work needs.

What a project costs in Battersea

Typical London jobs priced on our estimator in October 2026, ex VAT and indicative rather than a quotation:

A rear dormer loft conversion: £68,000 to £81,000.
A whole house refurbishment with a new extension: £1,100 to £1,350 per square metre of floor worked on.

Kitchen units, worktops and appliances are priced separately. Our minimum for a complete extension project, including finishes and fittings, is around £85,000. Our flat renovation cost guide and house refurbishment cost guide go into more detail, and the free estimate prices your own project in two minutes.

Working with MVV in Battersea

Just across the river in Chelsea we designed and built Margaretta Terrace, a Victorian townhouse with marble bathrooms, herringbone floors and a bespoke library, and in Streatham we built Milford Mews, a double storey extension with an open plan living room below and a principal bedroom suite above. For homes further west, see builders in Wandsworth.

Every project runs as one design and build service from our Chiswick office, with a single team responsible from concept to completion. We carry £10M public and employers' liability cover and plan deliveries, access and working hours around your street or your building.
