House Extensions in Tower Hamlets
Tower Hamlets covers a wide range of property types — from Georgian and Victorian terraces in Bethnal Green, Bow and Stepney to the high-rise new-build stock of E14. Extension and refurbishment work concentrates on the terrace stock in E2 and E3.
House Extensions in Tower Hamlets — what to expect
Bethnal Green and Bow terraces suit rear extensions — typically 3–5m kitchen additions. E3 has some wider plots that allow side extensions on semis. The E14 new-build stock generally does not suit conventional extension work. Conservation areas in Bethnal Green and Stepney restrict permitted development on many streets.
Tower Hamlets property types
Victorian terraces in Bethnal Green and Bow, Georgian houses in Stepney, new-build apartments in Canary Wharf/E14. The property type affects which extensions approach works best — we'll advise from the first call.
