Frequently Asked Questions

Can any Hampstead house have a basement conversion?

Most Hampstead properties can accommodate a basement conversion, but feasibility depends on factors including soil conditions, water table level, neighbouring properties, and structural considerations. We conduct thorough surveys before confirming feasibility and providing costings.

How much does a basement conversion cost in Hampstead?

Basement conversions in Hampstead range from £100,000 for a simple cellar conversion to £300,000+ for full excavation of a new basement. Costs depend on excavation depth, size, waterproofing requirements, light solutions, and interior specification. Full surveys precede accurate quotes.

Do basement conversions need planning permission in Hampstead?

Converting an existing cellar often doesn't require planning permission. Full basement excavations typically do, especially in conservation areas. Light wells, lighboxes, and external access may need planning regardless. Camden Council also has specific policies on basement developments.
