No home can promise survival from a nuclear attack. Close to a detonation, or in a mass fire, it may offer little. It can reduce some risks at a distance.

What shapes the work in Mayfair.

Planning shapes a protected room before engineering does. These are the local basement rules, and your house may add more.

Council: City of Westminster. Kensington and Chelsea’s CD11 does not apply here.
Depth: Policy 50 of the City Plan, adopted January 2026. One storey below the lowest original floor.
The garden: No more than half of it. Where a garden is 8 metres or less, a basement may reach 4 metres.
Listed buildings: Heritage assets must be protected. A listed house must keep its original hierarchy of spaces.
Conservation areas: Lightwells, vents, skylights and plant must be sensitively designed and discreetly located.

What Mayfair owners ask.

Can I build a bunker in Mayfair?

Sometimes. It depends on the house and the local basement rules. We start with a private feasibility review.

Would a bunker in Mayfair survive a nuclear attack?

We cannot promise that. We can plan a protected room within a basement, with specialist engineers.

What does it cost?

It is a specialist service, so we cannot give prices at an early stage. We price it once the brief is agreed.
