Idea: Identical mass-produced brick elements connected together to create a building. A design that uses blow-moulding technology to manufacture the modular brick element. This process is normally used to make water bottles and it is quite inexpensive. The bricks are designed to interlock with each other like a three dimensional puzzle and are then fastened together. The bricks have possible connection sockets which can be equipped with solar-panels on the outside which feed light-bulbs on the inside. An inner bridge object reaches throughout the entire tube to creates the liveable surface.
