This is one of the most distinctive streets in the UK but a number of large houses have gone out to rot on the Billionaire Row in North London.
There are 66 luxury houses in Bishop's Road in Hampstead but some have been abandoned and left to be cramped despite all their special prices.
Urban explorers have now gone into some of these down buildings to see what the state of the big houses have been before.
The site displays a gutting fern staircase with gold sheets, colored ceilings and an inner swimming pool.
The windows are covered by mattresses, a drop from the roof that falls down decreases the floor and the walls are damp.
The pictures show a swimming pool left at the Redcroft mansion, the Georgians get a flattering bracken and the Towers almost completely disappeared.
Some of these houses have been used for years by many without them since they were bought in the 80s.
Today, the street has a two-roomed flat with an average return building of around £ 3m and an expensive house for £ 15m.
A Guardian survey in 2014 found that the string of warehouses is approximately £ 350m.
Many were bought for about £ 1m in the late 80s, but some of them were unoccupied and would not let them rot while others were little used.
Currently, many of the sites in the street have been converted into associated buildings and offices, but a number of these houses have fallen sharply.
The Guardian found that 16 of the mansions on the road had been abandoned and others were used for a short time.
The newspaper found that one third of these houses were empty and had more than 120 bedrooms in empty houses.
Anvil Varma, main deputy developer, said: "One of the most expensive regions in the world".
No series of ten large houses was bought at least £ 73m after it was bought by the royal family Saudi between 1989 and 1993. t
At one time, Justin Bieber was renting a new grand house for £ 25k a week in the street.
The art collector Billju Zabludowicz and Richard Desmond are known to have lived on the street.
