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.

Leopards prowl the streets of Mumbai, peregrine falcons hunt amongst New York's skyscrapers, and a million starlings perform spectacular aerial dances over Rome.

As the architects of this environment, can humans choose to build cities that are homes for both them and wildlife?
