The Infozentrale auf dem Vollgut is a multi-functional building in Berlin-Neukölln that was realised in line with circular construction, usage and teaching principles; its primary users are the diverse socially minded group of actors of the Kindl Kiez neighbourhood. The Infozentrale was designed and realised by a group of 36 students as part of a DesignBuild Project from the Natural Building Lab and is constructed entirely from existing resources sourced from industrial, construction and office waste. The project offers an answer to questions relating to resource-positive construction in an urban context and embodies a new method of architectural production for a post-consumer society. A reversible and robust lattice of recovered timber beams forms the roof, while the wall elements utilise a system of upcycled cardboard boxes, filled with shredded paper insulation and pasted with excess advertising posters. In Spring 2020 an extra skin of timber formwork boards was added. Niches in the walls create different internal & external areas, that can be used for different functions and provide a general zoning system, allowing a large variety of different programmes to be accommodated. The surrounding terrace sheltered by the characteristic overhanging roof provides further space for encounter and interaction with the surrounding neighbourhood.
