There are life-sized giant lego bricks called EverBlocks. They can be used to build almost anything like walls, tables, chairs, shelves.
EverBlock Systems, LLC. is a modular construction materials company headquartered in New York City, New York, with distribution networks worldwide. It develops, produces, markets the modular plastic blocks which are used in a variety of construction applications, both personal and commercial.
EverBlock Systems primarily manufactures oversized polypropylene blocks that interlock with each other in order to create furniture, modify interior space, or create new structures. The blocks are similar in structure and utility to the toy bricks manufactured by The Lego Group, which has generated significant interest among customers who played with the plastic bricks as children.
The building materials can be assembled in any way the builder chooses. The company provides some templates which would allow the builders to create household furniture such as shelving units, tables, desks, catering stations, and bars. Some commercial applications have included using the blocks to construct interior building partitions, where larger spaces can be divided into multiple workspaces, cubicles, and entire offices.
