It is a house so colossal, the new owner could sleep in a different room every night of the year.
According to British media reports, Wentworth Woodhouse, a 365-room mansion in South Yorkshire, England, has a price tag of around £7 million ($12.67 million).
While this may seem cheap for a house twice the size of Buckingham Palace, it reportedly also comes with a renovation cost of potentially £42 million ($78.39 million).
On 100 hectares, the property has the longest facade of any private residence in Europe and is connected by eight kilometres of corridor.
As architecture blog Curbed points out, the home took so long to build that its west front was constructed in the Baroque style while the east facade is done in the Palladian style popular in the mid-18th century.
The current owner, architect Clifford Newbold, purchased the property in 1999 for £1.5 million and has spent £5 million over the past 15 years fixing it up.
There is still considerable work to do and the 90-year-old has decided to pass the task on to someone with more vigour.
