How can you over-engineer a door you might ask? Well, that’s a question answered by Matharoo Associates. They’ve designed, and built this interesting door above. It’s made of 40 individual sections of Teak, with 160 pulleys, 80 ball bearings, and a wire rope connected to a counterweight. Opening the door happens with a wave of each piece of Teak. It’s an elegant door, but completely over-engineered, for sure.
