Kevin McCloud meets artists Jana and Rory, who live in a former driving test centre in the east of Edinburgh but have ambitions for something bigger and much warmer to live in every winter. They want to replace the current building with a sleek, contemporary slipped box house with upside-down living to capture a view of the sea - and all on a minimal budget.

Kevin McCloud revisits couple Chris and Gill, who he last met in 2001 when they were renovating a disused textile mill near Huddersfield, West Yorkshire, into modern hi-tech accommodation with a minimalist interior. The presenter finds out how life has been in the house over the past 25 years, asking whether their meticulous approach has stood the test of time.

Kevin McCloud catches up with energy conservationist Andrew, who in 2017 decided to build a radical, self-heating home for his family - the first of its kind in the UK. The aim was to heat the house all year round by storing the warmth of the summer sun into insulated earth banks over & around the house, and then drawing the warmth back into the living spaces in winter. Six years since his last visit, Kevin McCloud returns to see if this groundbreaking experiment has proven a success.
