The World's Most Extraordinary Homes

Award-winning architect Piers Taylor and actress and property enthusiast Caroline Quentin (who previously presented Restoration Home for BBC Two) explore a range of incredible architect-designed houses in extreme locations around the world.

Whether built into the side of a cliff, nestled in a forest, perched at the top of a mountain or under the earth, these are homes that connect to their environment in a spectacular way.

Each episode of the 4x60' series is themed according to the houses' environments: Coast, Forest, Mountain and Underground, with Caroline and Piers travelling to locations ranging from North America, Australasia and Europe.

To explore how these dramatic designs function as both works of architecture and as real houses, they stay overnight, eat meals and spend time in the homes. Piers and Caroline are a new and entertaining pairing of a property expert and an architect, both bringing their own expertise, humour and experience as they meet some of the owners and architects of these incredible buildings.
