Loft conversions 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 loft conversions involves

A rear dormer loft conversion in Fulham costs £55,000–£85,000 and takes 10–14 weeks, adding a double bedroom and en-suite. You need at least 2.2m from the top of the ceiling joists to the underside of the ridge for it to work — measure that before doing anything else.

Consider this if

• You need a fourth bedroom without moving house
• The loft is full of boxes and has a decent ridge height
• You want a principal suite away from the children's rooms
• Neighbours on the street have already converted theirs
• You want to add value before selling
• Working from home needs a room with a door
