House extensions in Hackney Central

Hackney Central sits in Hackney, where the streets are dominated by 1930s suburban semis where a rear-and-side wraparound is the obvious move. The build that pays back most reliably here is a modest 3.5m rear extension under permitted development with rooflights over the island.

Typical all-in (inc VAT)
£120k–£180k

What we build in Hackney Central

Most Hackney Central 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. Victorian terraces (De Beauvoir, Stoke Newington), Georgian terraces (Hoxton), warehouse conversions (Hackney Wick).

Planning permission in Hackney Central

Hackney has stringent design guidance, especially around the many conservation areas (De Beauvoir, Clapton Common, Stoke Newington). Contemporary detailing is welcomed if it's sensitive to the terrace rhythm.

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

Party wall and neighbours

Almost every project needs two Party Wall Awards. Neighbours here are experienced — expect them to appoint their own surveyor.

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

Tight on-street parking means bay suspensions and timed deliveries — your builder should price this, not absorb it.

Every quote we issue for Hackney Central 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 Hackney Central

Light and layout move value here more than raw square metres — spend on glazing and ceiling height.
