To No. 01 : Acre mobi the structural system combines triangular, square and round space with the help of prefabricated system construction components to interlaced, flexible and multi-functional building structures. To No. 02 : System construction components for the multi-storey building design. Cantilever supports and retaining structures from the materials wood, steel or concrete. Buildings can be supplemented by these design features flexibly on, over or backbuilt as well as. The system supports contain the complete building drainage for dirt and rain water. All necessary connections are for each plane and for each corner in the support before-installed (see hole samples of the support drawing). 50% of the building sides/roof areas for ecological solar technology can be used by the triangular building form compared with square buildings, during suitable north adjustment of the system hold. To No. 03 : Space module conception from prefabricated steel components as cantilever retaining structure with Sheddach, flat roof or central roof for sales, presentation and exhibition booths. To No. 04 : Over tarpaulins of individual properties with the help of acre mobi the system hold. The interlaced building structure permits multi-functional uses and Umnutzungen. So effective areas can be planned by 60 - 100, 000 m ?up to the acre mobi park (trade area). Within this multi-functional Netzplanung can be e.g. assigned studio, apartment, office, off-position, production or stockrooms/buildings at will.
