WATCH: Can you solve the mystery of this house which time forgot – for sale for £150,000?

The home is completely hidden from view, situated between St Benedicts Street and Pottergate - and agents are baffled over its history. And because it's for sale by online auction, you don't even have to leave your armchair to buy it.

Number 36b, St Benedicts Street has two bedrooms and was probably built in the 1930s. Despite bombing of that location in the war, it miraculously survived intact. Records show it's only been sold twice, in 1998 and more recently in 2001 when the current owner bought it.

Ian Harris, manager at Watsons, selling the house, said: "In 35 years of doing this job, I never knew a house was there. The owner bought it and spent money on it in the early years but then moved away. Intruders got in and ran amok and wrecked the plumbing, leaving water running which caused immense damage.

"So it needs a complete re-fit but it really is a hidden gem in a very popular, trendy part of the city. I think it was built in the 1930s despite it having a Victorian fireplace. But we really don't know much more about it."

"We don't have lots of properties in our online auctions but it's definitely a popular way of selling a house, quicker and easier than by the traditional method," said Mr Harris.

The house currently has four people watching the auction but no bidders. Inside are remnants of its former glory. Inside it has a reception hall with what would have been an impressive staircase, a downstairs cloakroom, a sitting room and kitchen/diner with a large double-glazed conservatory at the rear. Upstairs is a bathroom and two double bedrooms. It is accessed from St Benedicts Street, down a gated passageway which you'd never notice and this opens up to gardens to the front and left hand side.

"This house is in need of significant repair, updating and improvement, having been neglected in recent years but great potential to make a fantastic individual and secluded city home in a discreet location," added Mr Harris.
