Many South Hampstead villas have a real advantage when it comes to extending: a generous private rear garden. Unlike areas built around shared communal squares, the houses here typically own their gardens, so a single-storey rear or side-return extension to create a bright, garden-facing kitchen-dining room is genuinely on the table — subject to the conservation area.
Most of South Hampstead lies within the South Hampstead Conservation Area, which values consistent rear elevations and roof forms, so an extension needs Camden planning permission and a design that respects the original house and the neighbours’ daylight and outlook. Properties outside the conservation area may have more permitted-development scope, so the first step is to establish exactly where you stand.
We confirm what your house can take, design an extension that is both useful and consentable, engineer the structure and the opening back into the house, and build it through to a finished room — one contract from drawings to handover, with honest budgets in pounds sterling.
South Hampstead’s private gardens make extending viable — the conservation area shapes how.
Villas typically own their rear gardens, so rear and side-return extensions are genuinely possible.
In the conservation area an extension needs Camden planning and a sympathetic, subordinate design.
Properties outside the conservation area may have more PD scope; we establish your position first.
