Water tower home for sale: six-storey tower has been transformed into a £1.5m luxury home with sky-high roof garden

A converted 75ft-high water tower – with more than 14,000sq ft of floorspace – is for sale in Warwickshire for £1.5 million.

The former industrial building was built in 1930 for the Corporation of Coventry and decommissioned in 2004. It was originally bought for just £25,000 at auction in 2009, but without planning permission.

The first private owner obtained planning permission and sold it to the current owners, as a post-industrial shell, in 2013.

The aim was to convert it into a family home, but having only previously handled a barn conversion, this epic structure proved to be quite a challenge.

It took 18 months of heavy duty work before it was habitable, including laying miles of cabling. Just cutting out each window took days – the walls are made of reinforced concrete and are a foot thick.

Spread across six levels (including a roof terrace, which the current owners use as an outdoor cinema) it has been converted and modernised extensively. Some interesting features have been retained, including the original spiral staircase.

On the ground floor there’s a gym, a games room big enough for a full-size snooker table and a self-contained guest suite with its own sitting room, kitchen and shower room. There's also a garage with a car lift.

On the first floor there’s a dining room, sitting room and the main kitchen with a terrace providing clear views across the local countryside.

There are six bedrooms spread throughout the second and third floor, three of which have en suite bathrooms. The master bedroom – located on the third floor – has a sitting room and dressing room.

The fourth floor – originally the tank room – has not yet been made habitable. At one time it contained 300,000 gallons of water that supplied Warwickshire.

It’s currently an empty concrete space, but occupies a cavernous 3,200sq feet, offering plenty of potential.

The current owners think it would make an incredible party space for entertaining and as the structure is not listed what could be done is limited only by the next owner's imagination.

If the height puts you off, you'll be glad to discover that a shaft was also installed during the conversion, ready for a lift to be fitted.
