S12E4: Off-Roader, Luxury Cabin and a Skip

A couple attempt to combine an army lorry and an old caravan to create the ultimate off-roader, and a man returns to his family's farm to build a luxury cabin. Meanwhile, George visits a building in Denmark that was designed to be a work of art and an office, checks out a skip that's been turned into a home, and takes inspiration for his scissor lift cabin from a stunning 18th-century bridge.
