House extensions in Putney

The properties we see in Putney

Putney's core is late Victorian and Edwardian terraces and semis, generally larger and later than Fulham's, with deeper rear gardens that make extensions straightforward. Towards Putney Heath and West Putney the stock shifts to substantial 1920s and 1930s detached and semi-detached houses with generous plots, accessible loft space and cavity walls — the easiest properties on our patch to work in. Along the river there are modern apartment developments with their own management constraints.

Planning in Wandsworth

Wandsworth is generally the most workable planning authority we deal with, and permitted development rights are more often intact here than in Kensington and Chelsea or the Fulham conservation areas. The 1930s stock in particular tends to have full permitted development rights, which means a rear extension and a loft conversion can often proceed under a lawful development certificate rather than a full application — faster, cheaper and much lower risk.

What extensions involves

A single-storey rear extension in Fulham costs £3,000–£4,500 per square metre, so a typical 20m² side return is £60,000–£90,000 and takes 14–20 weeks on site. Most Fulham terraces can extend under permitted development, but conservation area status changes that — worth checking before you design anything.

Consider this if

• The kitchen is a narrow galley at the back of the house
• There is a dead side-return alley you never use
• You want the kitchen, dining and living space to be one room
• The family has outgrown the ground floor
• You are choosing between extending and moving
• You want more light into a dark Victorian middle room
