This is a multi-functional furniture whose main purpose is to replace various functions for a Zero Energy House. Our furniture follows the four design principles. It has more than two practical functions. It serves as a coffee table where various objects such as portrays, decorations and or books can be placed on top. This furniture could also be turned into a one-person chair with a foot rest and a television table including three pillows pads. Lastly it can turn into a very comfortable twin bed that can reduce the use of space. Our furniture is well put together and it’s made of wood and foam which makes it very safe and easy to use. All different functions were kept simple and efficient and there is no reason why this should not be used in a Zero Energy House.
