Phase 1 Upper School renovations complete on Stanwich Road campus.

The Greenwich Country Day School (GCDS), a co-educational, independent day school, recently acquired the Stanwich School and is actively incorporating the property into their campus.

Colliers Project Leaders is providing project management services to assist GCDS in converting the former Stanwich School campus to a new Upper School (grades 9-12). The conversion projects were designed and constructed in multiple phases using two different architectural firms.

Phase 1, completed in 2019, included a new commons addition with a main entry to the school, administrative spaces, maker space, and a large multipurpose area. The existing building was renovated to convert the gym into a dining hall, upgrade the classrooms, and provide outdoor learning spaces. Site improvements included expanded onsite parking, a new synthetic turf field, and the addition of a new wastewater treatment plant.

Phase 2, slated for completion in late 2021, will include an addition to the existing academic building to add classrooms, choral, band, and science lab spaces as well as new locker rooms and athletic support spaces. The dining hall will also be expanded to include a full kitchen and added dining spaces.

Future phases will include the addition of a new performing arts center and several new art classroom buildings to form an arts quad in place of the existing north classroom building.

As owner’s project manager for both Phases 1 and 2, Colliers is responsible for representing the owner throughout all phases of the project, facilitating communications between all participating parties, and interfacing with the school’s constituents to ensure communication and coordination of project planning and construction activities.
