POTENTIAL war with Iraq has sparked a boom of interest in a £2.25m converted nuclear bunker.

Knight Frank estate agents has received a wealth of offers on the Glass House, in Kemnal Road, Chistlehurst, which has been sitting on the market for more than two years.

The 9,000 sq ft building was built in 1951 by the Ministry of War to protect Britain's military and political leaders in the event of an atomic bomb hitting London.

When built it contained a map room, living quarters, diesel-driven generators and communications equipment.

Converted by Piermont Homes, it is now a five-bedroom mansion with its own indoor swimming pool, three showers, two bathrooms and one of the largest roof conservatories in the country.

Estate agent Tony Dalton said: "After sitting on my books for a while I have recently had a number of offers on this stunning property."

Half buried and with walls 1.5 metres thick it could be one of the safest places to be in London.

But the Glass House is not the only safe place to be in Chislehurst.

During the Second World War up to 15,000 people at a time used the 20 miles of caves running under Chislehurst as a bomb shelter.

Bromley Council leader Councillor Michael Tickner said: "If a nuclear bomb was dropped then Chislehurst caves would certainly be a good place to be as long as there were enough provisions to last the fall out."

In the event of a high security risk, the Prime Minister and cabinet will be moved to one of three undisclosed underground nuclear bunkers in the countryside.

Speculation one of them is in Chislehurst could not be confirmed due to the potential security risk.

A Downing Street spokesman said: "There are contingency plans in place to insure continual Government.

"We cannot tell you the location of the emergency headquarters. All I can say is the safety of the Prime Minister and ministers is in constant check."
