Roominate combines the very best of modern construction kits with the classic dollhouse. Using these kits, kids actully construct their own playsets and dollhouses using a virtually unlimited number of design options. Once the structure is complete, kids use motors, pulleys and wires included in the kit to bring it into the modern age with features like lighting, fans and elevators that really work. Roominate provides a gallery of ideas of the company's website, but the true beauty of these kits is their versatility; kids can arrange the pieces into a dollhouse or basketball court, or craft a circular saw or refrigerator with equal levels of ease. Roominate is not only fun, but provides kids with important STEM skills (science, technology, engineering and math) related to architecture, electrical and mechanical engineering.
