"The relationship between biology and building is now in need of clarification due to real and practical exigencies. The problem of environment has never before been such a threat to existence. In effect it is a biological problem. Not only has biology become indispensable for building but building for biology."
(Otto, F. 1971. IL3 Biology and Building Part 1. Stuttgart: University of Stuttgart, 27.)
