Prime Build Works Limited

Builders in Clapham

Extensions, loft conversions, roofing and full home refurbishments across SW4 and the surrounding streets.

Prime Build Works builds for homeowners across Clapham and the SW4 postcode. Clapham runs from Georgian terraces in the Old Town to Victorian and Edwardian homes around Abbeville Village and grand conversions near the Common, so side-return extensions, loft conversions and period refurbishments are the sort of work we do here week in, week out. We run every stage in-house, from the first site visit through planning and building control to the final handover, so you deal with one team the whole way.

Where we work

Building work across Clapham

We cover Clapham and the streets around it across the SW4 postcode, along with the parts that run into SW9, SW11 and SW12 at the edges. That takes in Clapham Old Town, Abbeville Village, Clapham North and the roads around Clapham Common. If your home is near the Common, Grafton Square or the High Street, it is well within the area we work in.

Clapham sits mostly in Lambeth, with the west side of the Common in Wandsworth. We handle building control and party wall notices for both, which keeps things simple on terraced streets where walls are shared.

GOOD TO KNOW

Common questions about building work in Clapham

Which areas of Clapham do you cover?

All of it. We work across the SW4 postcode and the SW9, SW11 and SW12 edges, including Clapham Old Town, Abbeville Village, Clapham North and the roads around Clapham Common.

Do I need planning permission for a rear extension in Clapham?

Many single-storey rear extensions fall under permitted development, but Clapham has the Clapham Common Conservation Area and a lot of flats, where the rules are tighter. We check your address before any work and handle the planning application if one is needed.

How long does a loft conversion take?

A standard dormer loft conversion in a Clapham terrace usually takes around eight to ten weeks on site, depending on the design and whether you add an ensuite. You get a schedule with your quote.

Do you work on flats as well as houses?

Yes. Clapham has a large flat market alongside its houses. We take on refurbishments, kitchens and finishing work in conversion flats and mansion blocks, subject to freeholder and lease conditions.

Are you insured?

Yes. We carry public liability insurance and can send you the details before work starts.
