One of the winners of AR Emerging Architecture 2009 awards was Matharoo Associates for this amazing door design dubbed “The Curtain Door“.
At 5.2m high and 1.7m wide, the door is comprised of 40 sections of 254mm-thick Burma teak. Each section is carved so that the door integrates 160 pulleys, 80 ball bearings, a wire-rope and a counter weight hidden within the single pivot.
Stacked one above the other in the closed position, each plank can then rotate by a simple push causing the door to reconfigure into a sinusoidal curve.
