Castagna Realty

What Castagna Realty does

Castagna Realty Co., Inc. is a privately held, family-owned real estate development and management company headquartered in Manhasset, NY, tracing its origins to a 1922 masonry contracting firm founded by Ferdinand Castagna. The company owns, develops, and manages a diversified portfolio of premium commercial, residential, and mixed-use properties concentrated on Long Island's North Shore and in select upstate New York markets. Its flagship asset, Americana Manhasset, is an internationally recognized luxury open-air shopping destination featuring over 50 boutiques including Gucci, Dior, Cartier, Hermès, Prada, Louis Vuitton, and Tiffany & Co., complemented by Wheatley Plaza in Greenvale, NY. Residential developments include the completed Rock Rim Ponds (226 acres) and Brady Brook Falls (270 acres), with the in-progress Castagna Senior Park representing a 200-acre mixed-use senior community in Pawling, NY.

The company generates revenue through three primary streams: recurring rental income from commercial retail and office tenants, one-time sales of luxury residential home sites, and ongoing property management services for its owned portfolio. Notable commercial projects include the 230,000 sf LEED-certified Dealertrack Technologies headquarters developed in partnership with Tritec Real Estate Group, and Class A office/retail redevelopment on Franklin Avenue in Garden City via a joint venture with Albanese Organization. Castagna operates through both direct ownership/management and joint-venture partnerships (including with Simon Property Group for the proposed Syosset Park mixed-use project), targeting luxury retail brands, affluent residential buyers, corporate/enterprise office tenants, and the senior housing market.

The firm is governed by the Castagna family, with Catherine Castagna serving as President since 2019, Rita Castagna as Principal, and Robert Ronzoni as COO. The company has no disclosed external institutional investment, operates organically through project financing, and maintains a 100-year-plus brand reputation reinforced by philanthropic programs such as Champions for Charity. Geographic focus remains regional, serving Long Island, Westchester, Putnam, and Dutchess counties in New York.

Direct peers

• Simon Property Group: Largest US retail REIT and operator of luxury and premium shopping destinations. Simon is a direct peer on luxury retail real estate and is Castagna's JV partner on the Syosset Park mixed-use project, making it both a co-developer and the most natural scale comparable for Americana Manhasset.
• Westage Companies: New York Hudson Valley commercial real estate developer. Westage is Castagna's JV partner on the Castagna Commerce Park in Pawling, NY, with overlapping Hudson Valley / upstate New York geographic focus.
• Albanese Organization: Long Island / New York developer of Class A office, retail, and residential real estate. Albanese is Castagna's JV partner on Renaissance Development LLC and Franklin Avenue properties, with directly comparable development focus and Long Island footprint.
• Unibail-Rodamco-Westfield: Global operator of premium and luxury shopping destinations (e.g., Westfield centers in major US metros and Europe). Comparable to Americana Manhasset in positioning a curated luxury brand mix as a destination experience.
• Taubman Centers: REIT specializing in luxury and super-regional shopping centers with a tenant mix of high-end fashion and jewelry brands. Taubman's portfolio (e.g., Beverly Center, King of Prussia) is the closest institutional analog to Americana Manhasset's luxury brand concentration.
• The Macerich Company: Retail REIT focused on high-quality, fashion-oriented shopping centers in major US markets. Macerich's tenant mix and upscale centers (e.g., Scottsdale Fashion Square) directly mirror Castagna's Americana Manhasset positioning.
• RXR Realty: Large Long Island / New York Metro real estate developer and operator of mixed-use, office, and residential properties. RXR's Long Island / NY geographic concentration and mixed-use development focus directly parallel Castagna's portfolio, including the Glen Cove Garvies Point project cited in the source data.
• Tritec Real Estate Group: Long Island commercial real estate developer specializing in Class A office and mixed-use projects. Tritec is Castagna's JV partner on the 230,000 sq ft Dealertrack HQ and shares the same Long Island development DNA.

Broad incumbents

• AvalonBay Communities: Large-scale US multifamily / residential REIT with development exposure in high-growth suburban and urban markets. AvalonBay is a broad comparable for Castagna's residential development track record (Rock Rim Ponds, Brady Brook Falls, Hamlet at Carmel), though at substantially greater scale and institutional capitalization.

Regional players

• Vornado Realty Trust: NY-metro-focused REIT specializing in office and retail real estate including trophy Manhattan and select suburban NY assets. Vornado's NY geographic concentration and office/retail mix parallel Castagna's NY footprint, though Vornado is Manhattan-centric rather than Long Island-focused.
