Mods are square wooden frames which can be stacked on top of each other to form a partition or a solid structure. Perfect for stages, theatre performances, pop-up stores, fairs and exhibitions. They save 90% in conception and planning time, 40% in construction time and, because you rent, they are 45% cheaper. What's more, recycling means that you save on trees and metal reserves. Julien De Visscher has acquired a patent for the mods. Rapid expansion does not feature amongst his plans however, not least because he's keen to find out what the best growth model is from an ecological standpoint. Success must not come at the expense of nature.
