House extensions in Stroud Green

Stroud Green sits in Haringey, where the streets are dominated by solid brick terraces with shallow foundations and shared party walls on both flanks. The build that pays back most reliably here is an L-shaped wraparound that finally squares off an awkward kitchen.

What we build in Stroud Green

Most Stroud Green 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. Late-Victorian terraces (Crouch End, Harringay ladder), 1930s semis in Muswell Hill.

Planning permission in Stroud Green

Haringey is generally receptive to modest ground-floor extensions but the Crouch End and Muswell Hill conservation areas add design scrutiny. Front elevations are protected.

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 Haringey and both remove PD rights for rear and side extensions. Our London planning guide walks through the tests in order.

Party wall and neighbours

Ladder-street terraces almost always trigger two party wall notices.

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

Rear access via a side alley or garden gate speeds up muck-away and cuts labour cost noticeably.

Every quote we issue for Stroud Green 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 Stroud Green

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