Shared walls, settled early.

NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle party wall notices and awards in South West London SW. Fees are priced per project by our own quantity surveyor, from the actual scope. Call 020 7731 6841, and a budget estimate typically follows within seven days.
Almost every house in the SW postcodes is joined to another. A basement, a loft or a new steel can all touch a shared wall. The Party Wall etc. Act 1996 sets the steps.
Notices go out first. Work to the wall itself needs two months. A dig within three metres needs one month.
A schedule of condition then records the neighbour’s side, photograph by photograph. It protects both owners if a crack appears later.
In a house of flats, each floor may be a party structure. More owners means more notices, so we read the titles early.
