Grace Church School occupies all or portions of nine different contiguous buildings on Fourth Avenue owned by Grace Church. Parts of the property were built or renovated explicitly for use by the school.

Children in Junior Kindergarten and Kindergarten have a separate entrance to the school (94 Fourth Avenue) with access to their classrooms and a well-equipped playroof by elevator.

The school library of more than 18,000 volumes includes, in addition to the main reading room, a non-fiction research collection for the Upper School, Lower School collections and reading area, and an Upper School electronic reference center with CD ROMs, full Internet access, word processing and printing capabilities.

The dining and kitchen facilities connect to the school from the second floor of 80 Fourth Avenue. The third floor of that building joins the main building consolidating the Lower School in The Meg Duchovny Learning Center, which houses classrooms, a math lab, a computer mini-lab, rooms for learning specialists and areas for small group activities.

Science facilities include three well-equipped laboratories and a rooftop greenhouse. Computer facilities include a school-wide Macintosh network, a multi-unit computer center and two computer mini-labs. Every classroom, as well as the computer center, has Internet access; floating wireless labs equipped with laptops for an entire class are available for special projects.

The Robert Lehman Art Center includes two spacious studios, a ceramics studio with potters’ wheels and kilns, gallery space and a digital art center. Students have the use of a music room, two activity rooms for dance, music and drama rehearsals, a newly renovated performing arts space, and a playground.

The newly completed athletic center includes a regulation-size gymnasium with a climbing wall and a batting cage. The gym can be easily partitioned into two sections, allowing multiple activities. A smaller gym in Tuttle Hall, used by younger children and the after school program, has recently been renovated. An outdoor play yard provides space for both recess and classes. The sports teams also use the fields of East River Park and other nearby sports facilities.
