Tehran, Iran is known for its stifling summers and freezing winters, so most traditional homes in the area have a nice, cozy living room for winter and an open, light-filled one for summer. This house is by no means traditional and instead of offering two different living rooms for summer and winter, it instead offers three rotating rooms that can be open to the sun and wind or closed up against the harsh winters. The central structur is open, allowing the natural light from the glass ceiling and the open front windows to fill the whole home with a warm glow all year round.
