In this first episode, Kevin and co profile five amazing country homes on the long-list for the prize: including a large house camouflaged within a hill; a loving restoration in Wiltshire of a prototype modernist retreat; a Scottish home that blends an agricultural exterior with a sleek modern interior; and a slice of spectacular California modernism in Cornwall. Kevin then reveals which of these homes will make it onto the final shortlist.
