The Hamilton is a 21-story full-service cooperative constructed in 1963 with 144 residences offering studios through three-bedroom layouts. Architecturally it reads as a midcentury urban tower with practical floorplates and large window banks; many units have been renovated to feature hardwood floors, updated kitchens with stainless appliances and marble or stone surfaces, and period-appropriate built-ins. Interior apartment details commonly include formal entry foyers, separate dining areas or alcoves, sizable closets including walk-ins and his-and-hers configurations, and modern comforts such as central heat/air or individual HVAC units. Shared spaces emphasize convenience and city living: a staffed 24-hour doorman and concierge, live-in superintendent, central laundry, bike room, private storage and an on-site garage. Outdoors, the building offers a landscaped roof deck with river and city views plus planted garden areas and assorted private outdoor spaces attached to select units. The co-op’s policies and financial profile are notable — generally low maintenance fees, strong reserves, and flexible board approvals permitting pied-à-terres, co-purchasing, guarantors, gifting and subletting with approval; however, pets are not allowed. Located in Midtown East near Grand Central, the United Nations and transit hubs, it serves residents who want immediate access to transportation, dining and shopping.
