House Extensions in Newham — what to expect
Newham's terraced Victorian and Edwardian housing stock is well-suited to rear extensions. Standard 6m permitted development rear extensions, side returns on end-of-terrace properties, and kitchen extensions are the most common. The flat-roofed extension with roof lantern has become a signature look in E6 and E7 over the past decade.
Newham property types
Victorian and Edwardian terraced houses, post-war semis, new-build flats. The property type affects which extensions approach works best — we'll advise from the first call.
