Abstract: A software company based outside Madison, Wis., had a need for an auditorium as part of its campus expansion in 2011. The 829,000-sq-ft, 11,400-seat "Deep Space" auditorium was to be built underground, into a hillside, to preserve the views of rolling terrain and the farmlands beyond. It would feature a green roof and rockwork facing that mimic local geologic formations. The six-story building would require up to 74 ft of earth retention, including 60 ft of excavation beneath existing grades.
