645 W End Ave

A distinguished prewar cooperative on Manhattan’s Upper West Side, this 12-story building dates from the early 1900s and contains a small number of large, three-bedroom Classic Six–style residences. The architecture and interiors reflect turn-of-the-century craftsmanship: high ceilings, original millwork, oak parquet floors with inlays, leaded and stained-glass accents, French doors and occasional decorative fireplaces. Typical apartments offer formal foyers, separate dining rooms, eat-in kitchens and a former maid’s room often repurposed as an office or laundry. Common areas have been maintained and periodically refreshed; the lobby retains historical detailing while upper-level public spaces include a planted roof deck with Hudson River views and a rooftop fitness room. Building services and conveniences are oriented to full-time residents: a full-time doorman/concierge, live-in superintendent, bicycle storage, individual storage bins and a laundry room serve the co-op community. Policies are owner-focused and pet-friendly; some resale activity shows flexibility on guarantors and pied-à-terre use handled case-by-case. Located between West End Avenue and Riverside Park, the address places residents one block from green space, playgrounds and neighborhood retail, with multiple subway and bus routes nearby and easy access to riverfront views and promenades.
