Environment is a very popular issue nowadays so environment-friendly houses are finally becoming interesting. Domespace invented their semi-spherical houses over 30 years ago but only a few of them have been purchased and only around France, especially in Brittany, where the company is based.

The Domespace house plans were designed to optimize warmth by natural means, so the house actually turns to follow the sun and gain as much energy as it needs to keep temperature at an ideal level. If you don’t want warmth and sun-rays you can just set it to turn its windows away from the sun. You can command the engine to turn the house at a certain time or program it to do a full day rotation.[center]
