House Extensions in Tottenham — what to expect

Tottenham terraces in N15 and N17 suit rear extensions — 3–5m kitchen additions are the most common request. Many N17 properties have modest rear gardens but extension potential remains. The area's growing investor profile has driven increased extension and conversion activity.

Tottenham property types

Victorian and Edwardian terraces, post-war council housing, interwar semis. The property type affects which extensions approach works best — we'll advise from the first call.
