ConX is a Chassis Based Modular™ structural steel building system.  Inventor Bob Simmons had been working for decades toward a simple formula: Build more for less. He wanted to deliver better buildings, in less time, with less risk, and less cost to the customer. He rethought the entire lifecycle—design through delivery. His idea was to develop a modular structural system which could efficiently integrate pre-fabricated or modular building elements, such as pre-fabricated stairs, walls, bathrooms or kitchens. The result of this effort is a system that simply fits together elegantly, economically and sustainably and can be designed for dis-assembly and re-use fulfilling the Cradle to Cradle Certified qualifications and inspiration.
