The 134,000-sf Murray-Massenburg Elementary School in Durham, N.C., features several wings centered around an open courtyard. On track to be the first WELL-certified elementary school in North Carolina, the school incorporates views of adjacent wooded areas, maximizes natural light throughout its interiors, and provides a number of indoor and outdoor spaces to extend learning beyond the traditional classrooms. Evoke Studio Architecture designed the facility. LeChase Construction Services was the CM-at-Risk contractor on the project. Photo: Mark Herboth, courtesy LeChase Construction Services
