Do you believe intergenerational neighborhood models are effective at supporting long-term success for foster youth?

Following two decades of operation in Easthampton, the Treehouse Foundation is launching an expansion plan to add four new intergenerational neighborhoods across Massachusetts by 2031. This initiative, highlighted by a documentary screening on October 25, 2026, aims to replicate the success of its 60-home model.

Why it matters

The organization seeks to ensure children and youth in foster care grow up surrounded by permanent, loving families and supportive communities. By pairing foster families with older adult mentors, the model has demonstrated significant improvements in educational outcomes compared to national averages.

The Easthampton community currently features 60 homes, with 98% of youth pursuing post-secondary education. Boston has already committed $7 million in funding to support the development of the upcoming Olmsted Village project.

The players

Treehouse Foundation

This organization develops intergenerational neighborhoods designed to provide permanent community support for foster, adoptive, and kinship families.

City of Boston

The municipal government has provided $7 million in funding to support the expansion of the foundation into the local Olmsted Village project.

The details

The foundation utilizes a public-private partnership model that engages developers, government agencies, and philanthropic funders to create housing. No youth who have participated in the program have returned to state care for a new placement.

Market Landscape

The foundation's expansion represents a shift toward specialized, community-based housing models that aim to address systemic gaps in traditional foster care systems. This approach positions the nonprofit as a leader in private-sector social infrastructure development across Massachusetts.

The expansion of this model will generate 300 additional units of affordable housing across the state by 2031. Families in Boston, Worcester, and Framingham will soon have new opportunities to participate in these intergenerational living environments.

The takeaway

The success of the Treehouse model highlights the impact of stable, mentor-rich environments on youth development. Readers interested in community development can support these initiatives by participating in local housing policy discussions or volunteering as mentors.
