From the Victorian terraces around Battersea Park to the streets behind the Power Station, Battersea homes convert well. TrustBuilt Projects builds dormer, L-shaped and mansard loft conversions across SW11 and SW8 — full managed service from structural design to decoration.
Much of Battersea is two- and three-storey Victorian terracing, particularly the 'between the commons' streets it shares with Clapham. These suit L-shaped and rear dormer conversions, adding a top-floor bedroom with en-suite. Three-storey houses can sometimes take a more generous mansard, giving close to a full extra floor.
The Shaftesbury Park Estate ('Little India') and Park Town conservation areas carry stricter controls on roof alterations visible from the street, and there are pockets of listed housing. We confirm exactly what applies to your property and handle the planning route accordingly.
Battersea's rapid regeneration around the Power Station and Nine Elms has pushed up property values, which makes a well-built loft conversion one of the strongest investments in the area — the extra bedroom usually adds more in value than it costs to build.
Battersea loft costs are broadly in line with the wider South West London market; roof type and finish level are the main drivers. Typical ranges:
| Project type | Typical cost | Timeline |
|---|---|---|
| Velux / roof-light conversion | £30,000 – £43,000 | 6–8 weeks |
| Rear dormer conversion | £46,000 – £62,000 | 8–12 weeks |
| L-shaped dormer | £56,000 – £80,000 | 10–14 weeks |
| Mansard conversion | £66,000 – £95,000 | 12–16 weeks |
Every project is quoted in writing after a free site visit — these ranges are a guide only.
Two-storey Victorian terraces usually take an L-shaped or rear dormer; taller three-storey houses can sometimes support a mansard for close to a full extra floor. We assess the roof on the free site visit and recommend the option that adds the most space and value.
Yes in parts — the Shaftesbury Park Estate and Park Town conservation areas restrict street-facing roof changes, and some houses are listed. Rear dormers often proceed under permitted development; we confirm your property's status before pricing the work.
Generally yes. With values driven up by the Power Station and Nine Elms regeneration, an extra bedroom and en-suite typically returns more than the build cost — which is why lofts are one of our most-requested jobs in SW11.
Yes. The work is above your living space and most access is via scaffolding, so you can stay throughout. The new staircase goes in late in the programme, and we protect the existing house while we work.
