Rainer Kasik is partner of Xarchitekten. This is a group of dedicated architects who develop conceptual positions on contemporary architecture through project-related work. As a mathematical variable, the x represents openness. The x demands majority: the team with a flat hierarchy replaces the professional profile of the architect as a lone fighter. The dynamics of a permanent work process, oscillating between creativity and (self-) criticism, creates architectural quality above the capacities of each single member. The simultaneity of practical work and teaching or research – Technical Universities of Graz, Vienna and Innsbruck and Master Class Architecture of the Art University Linz - intensifying the work of x architekten. The activities of x architekten includes housing, office buildings, buildings for industrial, commercial, shopping and entertainment, design and urban planning.
