Ultimate DIY: Design your own 70-room mansion!
A lucky homebuyer can get this enormous manor complete with marble staircases, swimming pools, cocktail bar and wine room - but they will have to build it first.
The plot for the spectacular home is on the market for £7.5m but could end up costing up to £21m and the new owner would have to retain developer Stately Homes for the build.
When finished, Hampton Hall near Oxshott, Surrey, will have around 29,000 sq ft and 70 rooms, including 11 bespoke bedroom suites.
The manor will be built on the site of an older property on the Crown Estate at Oxshott and the buyer can alter or remove any part of the build.
Its jaw-dropping design spec includes 11 bespoke bathroom suites, personally-sourced marble, a luxury family kitchen, professional catering kitchen, a staff kitchen and walk-in refrigerated pantries.
