When a housewife wants to turn her bedroom around to face the sun, she can do it at the press of a button. A New Zealand inventor recently perfected the world’s first prefabricated revolving house. The inventor, Peter Lester, has protected his idea by taking out a patent on it.
    The first home built to his design is in Rotorua, New Zealand. The cost of the model is close to that of an ordinary home with the same floor space, 1800 square feet. The main house revolves like a wheel above the basement, which remains stationary. The plastic roof is semitransparent and softens the light. Roof binds in each room are controlled by an electronic system.
    The revolving house will be suitable in any climate. In hot zones the house can turn to a shady side for coolness, or it can rotate, at one revolution every four minutes, to catch as much breeze as possible.
