Building Project

Welcome to Dalton’s community resource page for our building project. We are adding two stories atop the 89th Street building for a STEM (Science, Technology, Engineering, Math) facility and undertaking selective renovations within the existing building to help students develop 21st-century skills. The project will not increase enrollment.

Project Scope

Raise the Roof

With its 100th Birthday, Dalton has an exciting, once-in-a-generation opportunity to reimagine our entire school for the 21st century. This investment offers an unprecedented opportunity to connect Parkhurst’s pedagogical foundation to the physical space facilitating project-based, experiential learning. 

Building Highlights

We are adding a 12,200 square foot, two-story rooftop expansion to our existing 12-story 89th Street building. Designed by Architects Skidmore, Owings & Merrill (SOM), our new facility will include a dedicated STEAM facility and open space for collaborative, interdisciplinary meetings and community events. The expansion gives us the flexibility to build on the success of our programs in the STEM fields, robotics, and transdisciplinary work. From top to bottom, this project ensures that we can serve each student in inspiring, new ways.

With an eye toward advancing Dalton’s mission – the master plan has re-organized the building into three simple programmatic groups:
  • Interdisciplinary Hub - On top, the STEAM center, a vibrant hub provides a central place for science, engineering, and art and promotes interdisciplinary dialogue, dynamic exchange of ideas, and meaningful collaboration. 
  • Academic Core - The middle, or academic core, is the hive of instructional spaces for both middle and high school students. 
  • Student Resources - The base of the building encourages community building with student resources such as the newly relocated, rejuvenated library, a renovated lobby with enhanced security, along with informal meeting spaces, the cafeteria, theater, and music. 
Recently named the Ellen C. Stein Center for Collaborative Study, our thoughtful, forward-looking design encourages interaction and chance encounters between students, faculty, and disciplines. The open communicating staircases, informal nooks, and pockets of seating allow for moments of spontaneous, serendipitous conversation, while movable classroom walls encourage collaboration, creativity, and exploration. 

This flexible place of new learning enables methods of teaching not yet envisioned and fosters new connections between faculty and students. Potential curricular innovations are boundless with the addition of a robotics field, prototyping space, an engineering lab, computer science & digital media rooms, a nutritional science kitchen, a greenhouse, and glass enclosed art studios adjacent to a dance studio – which doubles as a black-box theater.  Ample space is also available for art exhibits and science competitions.

Dalton Founder Helen Parkhurst called on Dalton to be progressive and adaptive, and Dalton has always innovated to serve our students in imaginative new ways. This evolution will ensure that Dalton lives up to its mission and lives out its values. It places equal emphasis on all disciplines – arts, sciences, humanities and is mindful of our historical emphasis on music, dance, theater and visual arts. 

By balancing holistic design and functional needs – along with a firm commitment to educational innovation – we celebrate Dalton’s legacy and centennial.

  • Will the streets be closed during construction?

    As required for safety, the street is expected to close temporarily during crane operations in coordination with the NYC Department of Transportation (DOT). Emergency vehicle and pedestrian access will be provided at all times.
  • How will you manage traffic on 89th Street?

    The School will position a flag person on Lexington Avenue and Park Avenue when the street closes for crane operations. During regular construction periods, lanes will remain open for regular traffic flow.
  • What are you doing to mitigate the noise?

    The construction manager will monitor noise levels to make sure the project complies with Department of Environmental Protection (DEP) requirements. In addition, the construction manager’s noise mitigation plan prohibits truck idling and requires the use of sound blankets to minimize noise from heavy equipment.
  • What is the School doing to address light pollution?

    All school spaces are equipped with motion sensors. Glass enclosed spaces are also equipped with downlighting and shades to minimize brightness.
  • Will there be security during construction?

    The School will have uniformed security and video cameras on site during construction.
  • How will Dalton protect our building?

    As required by the Department of Building’s (DOB), the School will erect a sidewalk bridge to protect pedestrians. Roof protection will also be provided as required by DOB.
