Abstract
Let be a right-angled building. We show that the lattices in share many properties with tree lattices. For example, we characterise the set of covolumes of uniform and of nonuniform lattices in , and show that the group admits an infinite ascending tower of uniform and of nonuniform lattices. These results are proved by constructing a functor from graphs of groups to complexes of groups.
