The Fundamental Group's designs may be inspired by geometric principles, but the burgeoning Berlin studio owes its existence, at least in an abstract sense, to another realm entirely: physics, ie, the field in which opposites attract. As architecture students at Berlin's University of the Arts back in 2003, Gunnar Rönsch and Stephen Molloy worked as assistants to rival department chairs, which in the world of academia, meant that they were automatically rivals, too. "If you sign up with one, you hate the other," Rönsch explains. "Mine was building construction and detail design, while Stephen's was based on a programmatic approach to structure — my chair basically had to solve all the problems created by his." In time, however, the pair realized the inevitable -- that by joining forces, they'd be stronger. First they became roommates, noticing how smoothly their collaboration on the apartment went, and then they began working together professionally, on projects like a friend's house remodel. Their only other major conflict came when it was time, in 2010, to choose a name for their new company: Rönsch & Molloy, or Molloy & Rönsch? "A mathematician friend of ours was sitting in our kitchen talking about the fundamental group — a term from algebraic topology that describes very complicated 3-D surfaces," says Molloy. "It was the perfect compromise."
