The Big Six: Super-sized rentals

Spitbank Fort, The Solent

Spitbank was built in 1878 as one of four defensive forts in the Solent. Decommissioned in the Fifties, it later became a private house and museum, before being bought by the owner of the Clarenco group in 2009, along with two other derelict forts. Following a £3m renovation, it's now available for exclusive use with nine nautically styled rooms, a rooftop hot tub and fire pit, a private chef and crew, several dining areas and a Laurent-Perrier champagne bar.
