The Dalton High School and Middle School are located at 108-114 East 89th Street in a 12-story, 104,000-square-foot facility. This project consisted of the construction of a new 2-story rooftop expansion. The focus of the expansion is the school’s new and improved STEM (science, technology, engineering, and math). New elements include a robotics laboratory, maker space, project room, engineering classroom, engineering offices, teaching kitchen, greenhouse, architecture/media arts, high school classrooms, restrooms, multi-purpose space, and structural reinforcement.

The Dalton School is an independent co-educational day school serving approximately 1,300 students from grades kindergarten through twelve. In 1929, construction of the 89th Street Building was completed, and it has since been continuously used as a school by Dalton.
