In the opening episode - after 30 years of living on the River Itchen in Southampton, Gerald Pragnell sets out to build an extraordinary futuristic fibreglass home, designed and made on his doorstep by his 27-year-old son Aidan. It's constructed from scratch by carefully building up layers of fibreglass to create two hollow hull sections. Gerald visits the job site often, adding luxury details to the design and keeping the pressure on his son, but all in good humour! So will Gerald end up the proud owner of a unique modern home that he wants - and thank Aidan for a job well done?
