The bunker has 8ft (2.5m) thick walls and steel doors
A former nuclear bunker in Hampshire which could house up to 30 people has been sold for £240,000.
The bunker, near Twyford village, was originally built in 1905 as a covered reservoir before being transformed into a nuclear bunker during the Cold War.
Auctioneers Clive Emson said it had failed to sell at a public auction but was bought privately afterwards.
The bunker has been used by computer security companies since it was decommissioned in 1997.
The auctioneers had said they had no idea who would want a property which has parking for 18 cars and the ability to withstand a nuclear strike.
The property, which was originally a redundant Victorian covered reservoir, comprises 2,500 sq ft (232 sq m) of office space with a kitchen and 4,800 sq ft (446 sq m) of storage space.
The building has 8ft (2.5m) thick concrete walls and a 6in (15.2cm) thick steel door, which meant it was ideally suited to withstanding a nuclear bomb during the Cold War.
Rob Marchant, auctioneer, said: "It's not yet clear whether the property will be converted into a Hobbit-style house, subject to planning permission, or be used as secure offices and storage."
