GFP Real Estate Launches Development Arm Led by Brian Steinwurtzel

• GFP Real Estate launches new development platform
• Brian Steinwurtzel named CEO of GFP Development
• Firm expanding focus on office conversions and adaptive reuse projects

What the new development platform means for GFP

GFP Real Estate has officially launched GFP Development, a new affiliate focused on scaling its growing development and construction business. The move formalizes years of expansion into redevelopment and conversion projects across New York City. By separating the development arm, GFP is creating a more focused structure to pursue larger and more complex deals. This includes ground-up development, repositioning, and office-to-residential conversions. For investors, this signals a push toward higher value creation strategies beyond traditional ownership.

Why Brian Steinwurtzel’s leadership matters

Brian Steinwurtzel will step into the CEO role of the new entity after serving as co CEO of GFP Real Estate. He has been a key driver behind the firm’s development and growth in recent years. Under his leadership, GFP has taken on major projects, including 100 Gold Street and the repositioning of several office buildings. His appointment gives the new platform experienced leadership as it expands into more complex deals. This transition also allows GFP’s main entity to stay focused on asset management and leasing.

How GFP is scaling development and conversions

GFP Development will focus heavily on adaptive reuse and office conversions, which have become a major trend in New York. Projects like 25 Water Street, 222 Broadway, and 40 Exchange Place highlight the firm’s strategy. With office demand shifting, many landlords are turning to residential conversions to unlock value. GFP is positioning itself to take advantage of this trend as more office buildings become candidates for repositioning. This strategy aligns with broader market demand for housing and more efficient use of older office assets.

What this means for New York real estate

New York continues to face a shortage of residential units while office vacancy remains elevated. Developers who can successfully convert office space into housing are gaining a competitive edge. By formalizing its development arm, GFP is preparing to scale these opportunities across its portfolio and beyond. The firm already controls more than 18 million square feet, giving it a strong base to execute on. For landlords and investors, this reflects a shift toward active asset repositioning rather than passive ownership.

What to expect next

GFP Development will work alongside GFP Real Estate, leveraging the firm’s existing portfolio and infrastructure. Additional leadership, including acquisitions and construction heads, will join as partners in the new entity. The launch also marks a continuation of the firm’s multi-generational leadership transition, positioning it for long-term growth. GFP’s move shows how established owners are evolving into full-scale developers, focusing on conversions, redevelopment, and long-term value creation in a changing market.
