School districts across North America are facing a crushing dilemma: invest millions of dollars to maintain outdated, educationally ineffective buildings or seek funding for expensive renovations, additions, and new construction to meet the evolving needs of today's learners. Compounding the issue is deferred facility maintenance.

This article discusses the kind of 21st century school configuration that not only reduces operational expenditures but also provides a safer and healthier educational environment.
