Graham Windham relocates to The Interchurch Center: NYC’s Hub for Nonprofit Collaboration & Impact, signing a five-year 9,833 s/f lease

Manhattan, NY According to OPEN Impact Real Estate (OPEN), the nonprofit organization Graham Windham, has signed a five-year lease for 9,833 s/f at the historic Interchurch Center, located at 475 Riverside Dr. in Morningside Heights.

Graham Windham is relocating to a newly renovated office suite on the 14^th floor of The Interchurch Center, a landmark nonprofit-centered office space and community center that exclusively houses ecumenical, educational and philanthropic organizations. The move reflects the organization›s desire for a modern, amenity-rich workplace that aligns with its mission while supporting continued growth and collaboration.

OPEN Impact Real Estate’s Stephen Powers, senior vice president Alexander Smith and Isabella Marcellino represented Graham Windham. The landlord, The Interchurch Center, was represented in-house. The asking rent was $29 per s/f, offering Graham Windham an affordable, high-quality workplace that supports the organization’s continued focus on responsible stewardship of its resources and careful management of overhead and operating costs. The transaction reflects OPEN’s longstanding relationships with both organizations, having advised Graham Windham on its real estate needs for more than a decade while partnering with The Interchurch Center over many years to help attract and retain mission-driven nonprofit tenants. Over the years, numerous OPEN clients have established offices at The Interchurch Center, benefiting from its collaborative community, shared amenities and programming designed specifically for nonprofit organizations.

The new space features floor-to-ceiling glass offices and conference rooms, abundant natural light and sweeping views of the Hudson River, Columbia University and the Manhattan skyline. The Class A building and community-driven space also offers several conference centers, a cafeteria, library, art gallery and soon-to-be-completed wellness center designed to support mission-driven organizations. The space is essentially move-in ready, allowing Graham Windham to transition into its new headquarters with minimal modifications before taking occupancy in August.

“Finding the right office for a nonprofit is about much more than square footage,” said Smith. “Graham Windham wanted a space that reflected its mission while providing employees with a modern, collaborative workplace and access to a community of like-minded organizations. The Interchurch Center checked every box, creating an environment where the organization can continue serving New York City’s children and families while becoming part of one of the city’s most established communities of mission-driven nonprofits.”

Originally opening its doors in 1960, The Interchurch Center is home to over 70 nonprofit, faith-based and social impact organizations including Bank Street College of Education, Columbia University and Children’s Health Fund, creating a unique ecosystem of mission-driven institutions. Founded with a mission to foster interreligious engagement and promote social good, The Interchurch Center remains rooted in traditions of hospitality, community care, and meaningful exchange. The relocation positions Graham Windham within a community dedicated to education, philanthropy and social impact.
