Southern Land Company has officially opened the Juliette, a major mixed-use residential project in White Plains. Located at 250 Mamaroneck Ave., the site previously served as the headquarters for the YMCA of Central and Northern Westchester.
Why it matters
The development helps resolve long-standing financial challenges and high maintenance costs for the YMCA by facilitating its move to a modern facility. This transition repurposes aging property into dense residential and commercial space in the heart of the city.
The Juliette features 177 apartments ranging from 626 to 1,868 square feet, supported by a 258-space parking garage. The development also includes a 2,196-square-foot ground-floor Starbucks.

Market Landscape
The Juliette project aligns with a broader trend of repurposing legacy institutional sites into high-density residential housing in suburban downtowns. This shift increases the local tax base while positioning developers to meet the growing demand for modern urban-style living.
Residents can expect new commercial retail options, such as the ground-floor Starbucks, which is now open to the public. Prospective tenants looking for new housing now have access to 177 additional residential units in the downtown area.
The takeaway
The transformation of the former YMCA site into the Juliette highlights how private investment can assist non-profits in exiting costly real estate holdings. Local residents should monitor future downtown residential developments for similar patterns of adaptive reuse.
