Old Farm Partners

Jonathan F.P. Rose serves as Managing Partner and is the ultimate decision-maker. He applies the investment philosophy he articulated in his book, 'The Well-Tempered City,' prioritizing projects that solve environmental, social, and economic problems simultaneously. His background combines practical real estate development from his family's Rose Associates with deep urban-planning expertise.

Old Farm Partners functions as the family office for Jonathan F.P. Rose, holding and deploying his personal and family capital. The Jonathan Rose Companies is a separate, mission-driven real estate investment and development firm that also manages capital for institutional investors. While both entities share the same founder and a nearly identical investment philosophy, the family office manages a discrete, privately held portfolio of his personal wealth.

The office focuses predominantly on direct investments in real estate assets and development projects, leveraging the family's five generations of operator expertise. Public records do not detail a fund-of-funds allocation strategy. Its posture suggests a preference for control or significant co-investor roles where the firm's design and planning standards can be directly applied to specific properties.

The wealth originated from Rose Associates, a multi-generational New York City real estate development and management firm founded in the 1920s. The firm built and managed a significant portfolio of high-rise residential properties across Manhattan. Jonathan F.P. Rose subsequently generated his own personal wealth through the Jonathan Rose Companies' successful urban development strategy.

The firm does not actively market itself as a co-investment capital source for external GPs. Its model favors direct sourcing and developer-level involvement in assets. If it does co-invest, it likely seeks a substantive advisory or oversight role to ensure the project meets the rigorous environmental and community standards that define the Rose investment filter.

Sourcing relies heavily on Jonathan F.P. Rose's public network as a thought leader in urban resilience, his civic board participation, and the family's century-long presence in New York real estate. The firm targets off-market and negotiated transactions in transit-accessible locations, often involving complex public-private partnership structures that require specialized expertise fewer competitors possess.

The office invests across the real estate lifecycle, from ground-up development to retrofitting and repositioning existing assets. Its sweet spot is complex urban infill projects in the middle-market range, where environmental engineering and community planning add measurable value. It does not engage in speculative land banking unless it is part of a broader master-planned resilient community concept.
