House Extensions in Hackney — what to expect

Hackney extensions are predominantly rear additions on the tight Victorian terrace plots. Side return extensions on end-of-terrace properties add valuable kitchen and dining space. The E8 and E9 market expects exceptional design quality — standard extensions won't cut through. Conservation areas in Dalston, London Fields and Clapton require planning permission in many cases.

Hackney property types

Victorian and Georgian terraces, converted warehouse and factory buildings, interwar council blocks. The property type affects which extensions approach works best — we'll advise from the first call.
