The new 140 Clarendon Street apartments in Boston’s Back Bay neighborhood, designed by Cambridge-based architecture firm PCA, provide permanent affordable housing with 210 new studio and one-bedroom apartments and a mix of community and amenity spaces. The conversion design doubles the number of apartments in the 1929 building while keeping several existing cultural and educational tenants in the multi-use building.
Developed by Beacon Communities in collaboration with The Mount Vernon Company, 140 Clarendon reimagines the Back Bay’s 13-story former YWCA. Dubbed “The Miracle on Clarendon” by the Boston Globe, the ambitious project arose from a collaborative effort by a team of development partners, architects, builders, funders, and neighbors. The property is managed by Beacon Residential Management. Pine Street Inn provides services for the 111 households who have experienced homelessness under the national Housing First model.
“The success of 140 Clarendon Street provides an inspired example of how public and private partners can collaborate behind a shared vision and solve seemingly insurmountable challenges,” said Darcy Jameson, Vice President of Development for Beacon Communities.
MEETING THE SPECIAL NEEDS OF THE TENANT MIX
Of the 210 apartments, 111 are designated for residents transitioning from unhoused to permanent housing. The remaining 99 affordable apartments are reserved for income-eligible households.
One major concern for the design team was reconfiguring the former hotel floor plates to meet the space needs and program essentials for a diverse mix of occupants. For example, the former YWCA floor plates had no kitchens, whereas all the new units required kitchens.
Nidhi John, AIA, a Principal with PCA and lead architect for the project, said, “Moving the project through its design and construction phases as quickly as we did reinforced the commitment of all our stakeholders to creating urgently needed housing for the most vulnerable among us.”
SUPPORT SERVICES PROVIDED BY PINE STREET INN
Pine Street Inn staff provides social and supportive services for the 111 residents transitioning to permanent housing. This nationally renowned nonprofit partners with people experiencing homelessness to help them move from the streets and shelters to permanent supported housing with wrap-around case management services.
“PCA’s work on 140 Clarendon Street is informed by their deep understanding of how to create affordable housing that meets a wide range of occupant needs,” said Jan Griffin, Vice President of Housing for Pine Street Inn. “The design provides a welcoming, accessible, and supportive experience in the building's individual apartments and community spaces. It supports our program goals and helps our residents thrive as they transition to permanent housing.”
TENANTS REMAINED IN PLACE DURING CONSTRUCTION
140 Clarendon’s existing residents and tenants remained in the building throughout construction, a challenge that necessitated a complex phasing of the renovation work. These tenants include individual residents, and the YWCA (the original building owner, which called 140 Clarendon home for almost a century), The Lyric Stage Company, the City of Boston Snowden International School, and Viga Eatery.
“We hear a lot from tenants and visitors about how the building is distinctive, and not at all institutional in its look and feel,” said PCA’s John. “From the lobby to the comfortable lounges on each floor, to the unique design and layout of each apartment, the occupant experience is warm and welcoming throughout. That is what we were aiming to achieve – a strong sense of home and belonging for everyone.”
