A modern modular take on flat-pack construction, Ten Fold Engineering has an innovative design that makes flat-pack housing and construction units desirable and luxurious. The buildings can adapt to need. Therefore, allow a broad range of purpose for a smaller amount of space. The opening and closing movement are powerless. The transition takes place via counterbalance levers and hinges. It only takes 10 minutes to set up a single unit using an 18V handheld drill. This “transformer like” method of construction is versatile, everything from homes, bridges, stands for sporting events, solar covers for parking lots and many more. These flat-pack designs would also be ideal for job fairs, pop-up markets, mobile hospitals and emergency facilities during disaster relief.
