Common Ground is the result of an experiment of revitalizing unused land in the middle of the city. By applying prefab methods, e.g. producing modules in a factory, transporting them to the construction site and assembling them on-site, it was possible to reduce the construction time of the 5,300 m² building to five months. In order to maximize the usage efficiency of the elongated rectangular shaped land, the architectural form is based on a center square connecting two buildings. At the traffic-heavy main street side, container modules were stacked to give the building exterior more impact and draw attention from passers-by.
