It takes longer than this-high speed video suggests but the house emerging from a grassy hillside in the Czech countryside, is putting a new spin on environmentally responsible living. Built by engineer Bohumil Lhota, the unique abode can be rotated to face whatever direction he chooses. During the daytime he can spin the house on its axis to make the most of the natural light and warmth from the sun. But if it gets too hot, Lhota's solution is to lower the house into the hillside - where the temperature remains stable at around five degrees celcius. The house is located about a hundred kilometres north-east of Prague. It took over 20 years to complete, with Lhota conceding it was a labour of love to get it built. (SOUNDBITE) (Czech) BOHUMIL LHOTA, HOUSE OWNER, SAYING: "Specialist engineers would have built this house much quicker than me doing it by myself. I would have been glad if someone had plucked up some courage and assigned the project to some professional firm to build it properly and quickly." It may have taken long time to finish, but as environmentally responsible buildings evolve, this house offers more than one new perspective on sustainable living, while turning heads at the same time.
