Trevor McIvor and his partners design buildings that take advantage of the innate heating and cooling characteristics of nature. From an off the grid “cottage” that requires no artificial cooling, to a green-roofed sound studio rising out of the earth, nature dictates the design flow.
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.
