First up is the historic city of York. The homeowners of three much-loved detached properties in the area have handed their keys over to five nosy neighbours...

They'll judge the perspective champions on three key criteria: the functionality of the home, the ambition of its interior design and finally, the ‘X factor'.

First up is a lovely Victorian railway cottage which, after a nine-year renovation project, is packed with ambition, style and train memorabilia. Next on the agenda is a 1960s farmhouse, a beautiful functional family home with every nook and cranny packed full of objects. Last up is a bungalow that's had a serious glow-up.

The owners of semi-detached properties to battle it out to compete in the final. Featuring a two-up, two-down 1930s home reinvented for the modern taste, another 1930s home more traditionally restored and a 1970s communal build with some surprises from its past.
