x architekten is a group of committed architects who develop conceptual positions on contemporary architecture through project-related work. As a mathematical variable, x stands for openness. x demands the plural: the team with its flat hierarchy replaces the professional profile of the architect as lone fighter. The dynamics of a permanent work process oscillating between creativity and (self-) criticism permit the emergence of a quality standard above the capacities of each single member. The activities of x architekten comprise the full range from housing and office construction, buildings for industry and commerce, shopping and entertainment projects to design and urbanism.
