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.

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.
