A flat that looks like the inside of the Star Trek Voyager is up for sale in Hinckley, Leicestershire.
The unusual property used to be occupied by Anthony Alleyne, who was jailed in 2013 for downloading thousands of images of child abuse.
His ex-wife is now selling the flat, because she doesn't want to be reminded of the past.
Allenye, who was an interior designer, spent 10 years and thousands of pounds converting his home.
It is on the market for £70,000.
However, because there is no cooker in the kitchen and the windows are obstructed, you can't get a mortgage on this property - so any buyers need to have the money.
According to the estate agent any potential buyers would also need to be vetted as they do not want the flat "to turn into a tourist attraction".
The advert for the property says: "Step in to the Voyager and let your imagination do the rest.
"This unique property has been custom-made by a real Star Trek fanatic. You won't find any other property like this one, this is truly unique, don't miss it!"
