Beatrice Sibblies
Managing Partner
BOS Development

Beatrice Sibblies is the managing partner of BOS Development, a community-focused real estate development and brokerage firm based in Harlem. BOS Development creates the spectrum of projects necessary for a vibrant community. BOS Development’s debut project, 88 Morningside, is an 80,000 sf residential co-op and community facility building structured on a 99-year ground lease from a Presbyterian church. With the building’s sleek interior and exterior design, the project received numerous accolades for its design quality. The project also resulted in the successful renovation and expansion of the church facilities and created an annuity for ongoing operations.

Based on the success of the 88 Morningside transaction, BOS has built a practice working with faith-based institutions to optimize their real estate portfolio. Current projects include development of a charter middle school in the Sugar Hill Historic District, creation of a new furnished rental platform in core Central Harlem as well as other hospitality, culinary and education projects. BOS Development has also formed an Opportunity Zone fund focused on real estate for education uses.
