What we build in Bush Hill Park

Most Bush Hill Park projects we scope fall into three buckets: a side-return or rear infill that fixes a dark galley kitchen, a full-width rear extension that opens the ground floor to the garden, and a rear-plus-loft package that adds a bedroom while the scaffold is already up. 1930s semis and detached homes with generous rear plots.

Planning permission in Bush Hill Park

Straightforward permitted-development pathway for most rear extensions up to 6m. Prior approval is the common route rather than a full application.

Before you assume permitted development applies to your street, check whether your street falls inside a conservation area or an Article 4 direction — both are common in Enfield and both remove PD rights for rear and side extensions. Our London planning guide walks through the tests in order.

Party wall and neighbours

Semi-detached typology keeps party wall costs modest.

Serve notice at least two months before you break ground. Budget £1,200–£2,400 per adjoining owner if they dissent and appoint their own surveyor — see the Party Wall Act guide.

Access, logistics and site set-up

Access is typically through the house, so expect dust protection, a boarded route and a skip permit from the council.

Every quote we issue for Bush Hill Park prices skip permits, parking suspensions, protection and welfare explicitly in the preliminaries — so the number you sign is the number you pay.

Value added in Bush Hill Park

Adding floor area is usually cheaper than moving once stamp duty, agent fees and moving costs are counted.
