Late last year, the K-12, all-girls Chapin School, at 100 East End Avenue, on the Upper East Side between East 84th and 85th Streets, applied for a variance to expand their eight-story, 168-foot-tall academic building to 11 stories or 183 feet in height. The expansion would increase the existing building by nearly 38,000 square feet to 170,285 square feet, according to the DOB, and would include additional classrooms, a dining hall, and gym. Earlier this month, the Board of Standards and Appeals approved the expansion, per DNAinfo, and construction will begin early next year. Completion is expected by the end of 2018, and NK Architects is the architect of record.
