Southern Land Company has officially opened The Juliette, a new mixed-use development at 250 Mamaroneck Ave. in White Plains. The project replaces the former site of the YMCA of Central and Northern Westchester, which has relocated to a new facility.
Why it matters
This redevelopment highlights the shift toward high-density mixed-use projects in White Plains as organizations like the YMCA look to mitigate high building maintenance costs through relocation. It also serves as a test case for developers navigating site acquisition and relocation assistance to unlock prime downtown real estate.
The Juliette adds 177 apartments and a 2,196-square-foot commercial space to downtown White Plains, supported by a 258-space parking garage. The development received financial incentives from the Westchester County Industrial Development Agency to facilitate the conversion of the former YMCA site.
The players
Southern Land Company
A national real estate developer specializing in large-scale residential and mixed-use properties.
YMCA of Central and Northern Westchester
A local non-profit social services organization that recently consolidated facilities to manage operating costs.
Westchester County Industrial Development Agency
A public entity providing financial incentives and tax support to catalyze economic development in the region.
The details
Southern Land Company began the multi-year process of acquiring the YMCA property in 2019 to clear the path for the new high-density structure. The building features varied unit layouts and high-end amenities, including top-floor units with ceilings measuring 12 to 14 feet. The project was facilitated by the company providing relocation assistance to the YMCA, which moved its operations to 148 Hamilton Ave. to address long-term financial and maintenance challenges.
Timeline

Market Landscape
The Juliette follows a standard industry trend of private developers utilizing local industrial development agency financial incentives to make large-scale residential construction viable. This project reflects a broader move to convert older institutional real estate in suburban downtowns into higher-density, mixed-use assets.
Property owners should monitor how developers use relocation assistance to acquire aging institutional properties, as this strategy is effectively opening new sites in downtown White Plains. Evaluate your own real estate portfolio for similar opportunities where maintenance costs exceed current utility.
The takeaway
The Juliette demonstrates that prime institutional real estate in White Plains is increasingly available for residential conversion if developers manage the complex relocation of existing non-profits. Watch how the 258-space garage influences local commercial traffic patterns in the 250 Mamaroneck Ave. corridor.
