Now that Kevin's cabin's glorious shingled shell has been finished, the next major task is to make it both habitable and magnificent. Kevin needs a solid, durable floor, a window to let in natural light, and most important of all, the heart of the home, a fire for heat. As Kevin wants to reuse, repurpose and recycle as much of his building as possible, he decides to turn a 1930s heavy steel safe into a wood burning stove. But he has to use the dangerous tool of the 70s bank robber, a thermic lance, to do it. Kevin tries to build a cheese floor, an ancient Viking invention that uses milk. And then for perhaps his toughest test yet, Kevin attempts to make glass from scratch using sand. To celebrate the next stage of the building, Kevin's friends burn a wicker man, a pagan tradition, to scare away any vagrant woodland ghosts that might haunt the new cabin.

Luxury is the one thing Kevin hasn't yet got at his handmade cabin in the woods. It's an off grid marvel, but what he really wants is a hot tub he can relax in, sip red wine and stare at the setting sun with his friends. He heads off to find a unique solution for his hot tub at an airfield graveyard, while making a luxury bath robe out of alpaca wool and fashioning a 'drop down' veranda. At last, Kevin's wondrous cabin looks finished, but he wants to give everyone who has helped him a house warming to remember.

Kevin starts work on his hand made home by venturing into the bowels of London. With mains electricity and gas not an option for his bolt hole, Kevin hopes to make biodiesel for a lamp from the huge stinking 'fatbergs' that clog up the city's sewers. For the cabin's structure, Kevin cuts down two ancient oaks, and starts putting together the wooden shell of the building. He also experiments with a Wild West technique of splitting logs by gunpowder, and tries to make the whole cabin mobile because of planning regulations.

Kevin builds a sun lounge for his beach hut, his own hammock to lie in and some lobster traps made out of old shopping trolleys to go fishing with. Kevin sets about doubling the floor space by building a beautiful, glistening sun lounge out of recycled windows culled from lorries and aeroplanes, coming up with a crafty design that floats the windows in mid air. Kevin also wants his own hammock to lie in and uses a massive anchor to build a giant-sized hammock that rotates, allowing him to chase the sun across the sky at the turn of a wheel. In search of more junk he can recycle, Kevin takes a dirty dive into London's oldest dock and discovers a haul of old shopping trolleys which he re-purposes into lobster pots.
