A property built on top of a specially designed cave has gone on the market for offers above £1.75m.
The 19th century home was originally built to house the owner's collection of statues.
The five-bedroom house, on the Park Estate in Nottingham, is being advertised by estate agents FHP Living, who confirmed it comes with planning permission to build a 7,000 square foot contemporary home on top of the 'enchanting' caves.
The column caves were designed by Alderman Thomas Herbert, a wealthy lace manufacturer, between 1850 and 1876.
They were originally designed to house Herbert's collection of full-sized statues of gods, druidical figures and Jesus.
In its current form, the property boasts a large entrance hall, sweeping staircase, modern living room and lounge diner, according to the agents.
There is a breakfast kitchen fitted with modern units and appliances, a utility room and two further bedrooms - one with an en-suite shower room.
Double doors provide access to a spacious lounge and dining room featuring French doors and large windows allowing an abundance of natural light
The three-storey house also has planning permission for a major redevelopment.
An artist's impression created by Jackson Crane Architects shows permission for an 'iconic architectural masterpiece' built on top of the sandstone pillared caves.
The development would more than double the size of the house on the existing plot, according to its listing.
