Kevin McCloud follows the progress of Zahid and Ferzana from Leeds as they set out to transform an obsolete coastguard station in East Yorkshire into a cantilevered, three-storey home made of steel and glass to enhance their panoramic sea views. With a tight budget of £325,000 and a goal of finishing in 10 months, the pair had their son Yusef manage the project but when Yusef gets a career opportunity he can't turn down and Covid hits the couple's business, will they be able to stick to their budget and time frame?

In Lincolnshire, high-flyers Zara and Giuliano set out to build a 400-square-metre malthouse-inspired home, but run into problems from the get-go. Can they get the project off the ground?

In West Yorkshire's rolling hills, Kara and Jonny build a striking stone and zinc home. The challenges come in thick and fast, but can they can pull it off and redefine accessible design?

Physical therapist Ara and researcher Tony set out to create a home focused on health and wellbeing on a woodland clearing near Henley-on-Thames. The pair plan to live on site to cut costs with Tony taking on the task of project managing to save Ara any stress that could compromise her already fragile health but as problems arise both Ara and Tony end up labouring onsite and what was meant to be a house of healing is in danger of becoming the opposite.
