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 Marylebone owners ask.

Can I build a bunker in Marylebone?

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

Would a bunker in Marylebone 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.
