Chill-Out Den, Sphere, Hastings

In the final episode of the series, George heads to the south coast to meet a father and son duo who plan to convert an oil rig escape boat into a floating holiday home. But without fixed plans will they sink or swim? George also visits Cornwall, to see a one-of-a-kind rooftop chill-out den, the brainchild of madcap inventor Brad, who'd set his sights on creating the perfect sphere. In Spain, George rounds off his tour of revolutionary small space design with a trip to an ingenious studio apartment by the sea with rotating internal walls. And it's the big day for the team's expandable camper, as George and Will take her to the coast for a maiden voyage at the grand opening on Hastings Pier.
