Caravan, Tree Tent and Tube Carriages (S01E04)

George encounters Ruth Tidd, who is working on transforming a former chicken caravan into an ice cream shop. He also witnesses the construction of the nation's first tree tent and gets a chance to test it out himself. Additionally, he visits some extraordinary offices created from four repurposed tube carriages. His journey takes him to Barcelona, where he explores a compact studio flat that cleverly operates like a five-room apartment. Meanwhile, during his own caravan project, George comes up with a unique design for a sofa that can also function as a bath.
