Kevin McCloud follows John and Julia, who are realising their 30-year dream of building an amazing house designed by architect John after years of bad luck. They have secured a plot at Graven Hill in Oxfordshire and John has designed a modernist wedge of a home for them to retire to. But as soon as they start, their run of bad luck continues - the lockdown brings construction to a halt and every month in their expensive rented house eats away at their budget - in turn threatening their vision for a comfortable retirement.
