Grand Designs: The Streets

Kevin McCloud follows the progress of Army couple Leah and Craig, whose lives have been dictated by the military. They have designed a contemporary, timber-clad kit house where they can escape from the beige of the barracks. Kevin also meets Jitinder, who works as a consultant helping businesses operate more efficiently - skills he is using in the process of building his own Hollywood Hills-style bachelor pad.

Kevin meets Joanna and Ben, who are channelling all their ingenuity to realise their vision of building an American ranch-style house in a gritty part of Glasgow on a tight budget.

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.

Prabhjot and Shalini's new-build is a super-quick kit house which should go up in a matter of weeks. But with such a close community, their home will need to take their friends' tastes into account as well as their own.
