HM in Motion will rework the north side of campus, bringing synergy to the quad and enhancing the learning environment for our students. The keystone of our master plan is a building which will house Upper Division Science and a Campus Center. This building will seamlessly connect to a new pool and updated Prettyman Gymnasium, through which students will easily access the east and south sides of campus. Additional community space will provide a home-like atmosphere in which our students will develop and foster important interpersonal skills and lasting friendships.

A new science facility will provide space for the Upper Division science program. In addition, Pforzheimer Hall will be renovated to accommodate and enhance our Middle Division science program. The new and renovated science facilities will be designed and equipped to support basic and advanced courses in established and emerging disciplines that students require for contemporary and future science literacy and research. In addition, the flexibility of the spaces will enable the new facility to serve the needs of the school far into the future as the curriculum evolves. An expanded menu of course electives could include astronomy, exercise physiology, food science, anatomy, additional environmental classes, microbiology, forensics, and expanded engineering electives and programming, including circuit and structural design.

New Science Facility Highlights

  • The easily transformable spaces will support teaching science in new and different ways with an emphasis on actively engaging students in daily coursework.
  • Nine Upper Division teaching labs and six seminar classrooms are designed to provide flexibility for how we teach courses, configured for classroom or laboratory work at any moment.
  • A student/faculty research lab will be large enough for 34 students and/or faculty members to conduct independent research projects concurrently.

Pforzheimer Hall Renovation Highlights

  • By moving Upper Division Science to the new facility, the space it currently occupies in Pforzheimer Hall will be reimagined to support Middle Division Science.
  • The new, well-purposed spaces will alleviate scheduling issues and allow for creative learning during science classes, electives, and clubs.
  • One floor will provide six Middle Division teaching labs and two additional areas for HM’s John Dorr Nature Laboratory related projects.
  • The renovations will allow the Middle Division to offer and support a variety of cross-disciplinary electives in a less crowded atmosphere.
  • Additional space can be used for general classrooms, Middle Division meeting and conference areas, and additional storage.

The ability to move seamlessly between classroom and lab will open up new opportunities for how we teach our classes and the variety of science electives we can offer. In the near term, we envision adding many experimental activities to our lessons, and incorporating more project-based work into both existing and new courses.

A Campus Center will be constructed on the first floor of the new three-story Upper Division science building. The Campus Center will become the hub of student life during the day and provide a safe and environmentally-conscious facility after school hours. This space is geared toward the overall well-being of our students, as socially-confident students are better learners and leaders. Some of the best collaborative work is accomplished in unstructured time and space.

New Campus Center Highlights

  • A large gathering space for group studying and socializing will foster a greater sense of community and give rise to increased opportunities for interaction between students and adults and allow the Library to return to a quiet study space.
  • The Campus Center will feature meeting rooms, media rooms, a student publications suite, and dedicated space to support clubs and extracurricular activities. It will also be home to our Center for Community Values and Action.
  • The new space will enhance the experience of every member of our community—our students, our alumni, our parents, and our faculty and staff members—who will now have a common place to interact.

Our students are deeply invested in the passionate exchange of ideas. They debate, persuade, argue, and collaborate, in our classrooms, hallways, and on our playing fields. The dialogue never stops, whether it’s in person or in print. The Campus Center will give these dynamic conversations a home, reflecting the heart of our core values, and allowing us to grow as a community.

The School will construct a swimming pool facility behind Prettyman Gymnasium that will support physical education instruction for students in grades N-12 and incorporate all the requirements for athletic competition. Swimming is a lifelong sport, and one that is a fundamental part of the HM experience.

New Swimming Pool Highlights

  • The Pool will have eight, 25-yard regulation lanes, an extra large pool deck to accommodate both young and old students as well as academic programming, state of the art filtration and starting blocks, and sound-dampening material.
  • It will be eligible for USA Swimming certification.
  • With one third of the floor capable of going from nine feet to just under an inch, we will be able to dramatically increase our N-12 education offerings and include lifeguard certification, advanced water rescue and instruction in whitewater rafting and canoeing.
  • Energy-saving systems will supply heating, cooling, and proper ventilation.
  • The Pool will also serve our:
    • Science curriculum through the study of waves and weightlessness, the study of stream erosion, the study of forces, and the study of pollution as it pertains to bodies of water.
    • Health and wellness programs through swim lessons, regular access to the pool for student directed exercise routines, and an array of activities including but not limited to strength and conditioning in the shallow end of the pool and the rehabilitation of athletic injuries.

The mind/body connection is extremely important. Students learn best when they are actively involved in a lesson. The pool provides unlimited academic and wellness opportunities for our community.

All students on the Bronx campus will benefit from the long overdue refurbishment of Prettyman Gymnasium. This project will maintain one of our school’s historic structures while increasing its capacity to serve the needs of students, faculty members, coaches, and spectators. Prettyman Gymnasium serves as an important epicenter on campus. It will be redesigned to better support the constant stream of activity it receives, while encouraging a focus on wellness and physical activity.

Prettyman Gymnasium Renovation Highlights

  • Prettyman Gymnasium will feature updated gymnasiums and spectator seats, a new multi-purpose room, team meeting and classroom space, and upgraded locker room.
  • The removal of the old swimming pool will help create space for an inspiring new fitness center complete with state of the art cardiovascular and strength training equipment. The new fitness center will allow for walk-ins and be open early in the morning until the late bus, including some Saturdays.
  • An enhanced reconditioning trainer’s suite included in the fitness center will allow the trainers to have increased interactions with student athletes.
  • The aerobics studio will overlook the fitness center, providing space for yoga and spin classes.
  • A new heating and cooling system will provide energy-efficient comfort.

Prettyman serves as an integral part of the HM student experience. Through physical education and athletics, students learn important values that enhance their academic development.
