George has the idea of turning a rusty scissor lift into a cabin in the sky and starts his Denmark trip with a visit to a modern take on the old Viking longhouse. After a bus from a previous series burned in a fire, its owner replaces it with an ambitious new build made of four shipping containers. Plus, a beautician and her daughter create a four-wheeled beauty parlour.

George meets an actor moving up the four-wheel property ladder and visits an underground bar in Denmark covered in seashells. Plus: It's full steam ahead for a dog-friendly holiday let.

A man pays homage to one of the great modernist homes with his new garden room and George visits the teenager who created a shepherd's hut last year, to follow his latest build. George visits a bizarre garden folly inspired by a wedding cake, a striking beach house inspired by pill boxes and an old RNLI station. In Denmark, the architect checks out a stunning circular house inspired by the owner's car collection.

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.

George meets a couple turning a derelict water pumping station into a luxury holiday home and an outdoor swimmer building a futurist micro camper. Plus: a glamping tree pod in a Danish forest.

George follows two eccentric builds, as a couple fit a camper on the back of a tiny Italian Tuk-Tuk and a dad-of-two creates a quirky getaway in an abandoned nuclear bunker.

In an incredibly ambitious build, a man attempts to create a mini canal and lock to house a narrowboat. And in Denmark, George visits a one-bed hotel housed in an old industrial crane.

George meets a couple turning a ship's wheelhouse into a glamping pod, revisits a designer from the very first series to see his gorgeous new eco-builds, and finally reveals his cabin in the sky.
