Loft conversion and extension builders. FMB members.
Local project guide
Putney has a varied mix of terraces, semis, mansion flats and larger detached homes. The right option may be a loft, a rear extension or a phased refurbishment; our first review focuses on which route improves the plan without creating unnecessary structural work.
Completed work
Straight answer: we haven't got a finished Putney job on this site yet. The nearest are our rear kitchen extension in Wandsworth, next door in SW18, and our East Sheen extension further along the Upper Richmond Road.
If you live on the Dover House Estate, you're on a 1920s London County Council cottage estate that's a conservation area with an Article 4 Direction. Many changes you can see from the street need planning permission there, so check before you order new windows or doors. Our Wandsworth Article 4 guide lists the others in the borough.
Putney is Wandsworth borough, so skips and pavement scaffolding need council licences, the same as anywhere else in the borough.

Typical project build prices, excluding VAT and professional fees (design, structural engineer, Building Control, party wall and planning fees). Prices are the same across every borough we cover; access and logistics (parking, skips, scaffold, restricted access) can affect the final price. Your fixed quote follows a site visit.
