Sanitation facilities and a little kitchen were also missing. An especially interesting problem to solve was the power and data supply of the new workplaces in a building, without destroying the original material. Called the “Schokoladenfabrik” the building is one of the oldest preserved commercial buildings in this part of Berlin. All design considerations were driven by the wish to show and preserve the existing in it’s original form. The removal of later additions and unorderly structures was therefore the starting point for the spacial concept where the whole unit was reorganized, with added structures.
