A couple who sketched their dream home on a piece of paper while on holiday and then built it from scratch have put it up for sale - for £3.5 million.

Builder turned artist Barry Surtees and his wife Julie wowed the nation when they successfully designed and built one of the most ambitious, state-of-the-art houses in Brighton.

The drama unfolded on Channel 4’s Grand Designs programme, during which Mr Surtees painstakingly created his stunning six bedroom and six bathroom DIY job, complete with a swimming pool, sauna, gym, fantasy bedroom and Japanese roof garden, in Withdean Road.

Mr Surtees, who used to work in the construction industry before he retired to build the new home, has single-handedly transformed the face of the moneyed suburb known as the Withdean Hills.

Now though Mr Surtees has decided to sell up and look for a new project but said moving from the home would be difficult.
