Mountain

They begin in California, viewing a property built from the wings and tail fins of a Boeing 747. In Arizona, the pair stay in a modern house with an innovative take on an ancient technique of absorbing the heat during the day and releasing it at night. In New Zealand, Caroline and Piers view a house camouflaged using cedar cladding, while their last stop takes them to a hexagonal alpine chalet with a steel chimney core that anchors it to the mountain.

Forest

Architect Piers Taylor and actress Caroline Quentin explore unusual homes built in or near areas of forest. After trips to properties near Madrid and the Catskill Mountains in New York State, they arrive in Piha, New Zealand, to a house built within an indigenous forest of pohutukawa trees. Navigating very strict environmental laws, this wooden-cladded and glass-roofed property mimics the branches of the surrounding trees, while its huge sliding glass walls open up to allow the surrounding forest to become an intrinsic part of the house itself.

Coast

Piers Taylor and Caroline Quentin visit an island in Norway, spending two days in a house built on a footprint of just 100 square metres. In Spain, the pair head to a home built into a steep cliff face overlooking the Mediterranean, featuring a cantilevered terrace offering maximum sea views and a swimming pool as well as an unusual tiled roof. After viewing a house in New Zealand crafted from two separate wooden cladded structures, the duo explore a home in Canada inspired by two ships in dry dock, designed to peer over the coast, allowing the sea to pass underneath.

Underground

Piers Taylor and Caroline Quentin explore unusual homes built underground. In Greece, they view a house hidden beneath the landscape that still boasts stunning sea views. In the Swiss Alps, they visit a house made so invisible it has to be accessed via a tunnel. Next it's over to New Zealand's South Island to a house built underground to soften its impact on the landscape as well as withstand the threat of earthquakes, before the pair inspects a Dutch house created by deep excavation, which features a huge, light-filled open-plan living space.
