Located in the heart of Missoula, Sussex's beautiful, 3.5-acre campus is an essential component of Sussex's progressive approach to education. The campus contains plenty of different types of play spaces, including traditional play structures, grassy fields, wild space, and open courtyard areas. The unique integration of natural elements help preserve and enhance elements of childhood by encouraging imaginary play, cooperation, freedom, and fun during recess as well as before and after school time.
Sussex features one historical building constructed at the turn of the 20th century and two Gold LEED-certified buildings. Sussex School is the first educational institution in the state of Montana to build LEED-Certified buildings. Construction of these buildings demonstrated how Sussex values conservation and environmental stewardship. Elements of the design include solar panels, locally-sourced wood, low/no-toxicity paints and finishes, low-flow plumbing, energy-efficient windows, solar tubes, and radiant heat.
Sussex classrooms feature a science lab, an acoustically-designed music room, a full kitchen, a stage for performing arts, and an art studio. Also on-campus are beautiful trees and greenery, an edible school-yard garden, a soccer field/hockey rink, a basketball court, play structures, and a seasonally-running irrigation creek.
