House Extensions in Hither Green
Hither Green is a well-connected South East London suburb popular with families and professionals. The SE13 postcode has a strong stock of Edwardian terraced and semi-detached homes that lend themselves to loft conversions and extensions. RCB Design & Build works regularly in Hither Green on projects that add space and improve how the ground floor functions.
House Extensions in Hither Green — what to expect
Hither Green's Edwardian terraces are well-suited to rear ground floor extensions. The typical floor plan — narrow and deep, with a rear kitchen and separate reception rooms — benefits significantly from a rear extension that opens up the kitchen and connects it to the garden. Most 3–6m rear extensions are achievable under permitted development. Side return extensions are a strong option on end-of-terrace properties.
Hither Green property types
Edwardian terraces and semis, Victorian cottages, some inter-war housing. The property type affects which extensions approach works best — we'll advise from the first call.
