A snowy January morning didn’t keep Friends Seminary students, faculty, staff and trustees from marking a construction milestone in the redevelopment of their campus in New York City. A crowd gathered on the new play roof atop the new two-story classroom and office addition to Hunter Hall for a ceremonial ribbon-cutting to celebrate the nearing completion of its construction. The campus redevelopment project, designed by KHA, includes the Hunter Hall addition and renovations to three adjacent townhouses. The new classrooms and offices in the addition will first serve as swing space for the townhouses while they undergo renovation, which includes matching their floor levels to Hunter Hall. The townhouses and addition include new classroom spaces that support collaborative learning and interdisciplinary work, a rooftop greenhouse, and a multi-purpose Great Room with retractable theater seating. A carefully coordinated construction schedule allows the K-12 independent school to remain fully operational during the entire project.
