In 21st-century Scotland, finding the perfect home - or any home - can be a challenge. The kinds of homes, and where we want them to be, are changing. And house-building projects across the country are following new models. With more people working from home, tenements are being turned into workspaces - one in Glasgow is even a TV studio. With land and houses in short supply, some people are turning to more radical solutions, and making their homes in houseboats or caravans to save money and live an outdoor life. And as Scotland's population gets older, the need to create homes for the elderly is sparking innovative solutions. From a brand new town being developed in Aberdeenshire, to a houseboat on the canal, and even to a 200-year-old castle, this documentary tells the story of Scotland at home through a diverse range of characters - and the homes they live in.
