19 E Catherine Street "CASTLE IN THE SKY" - Nyack has earned its title as one of the Hudson Valley's most coveted enclaves, celebrated for its river town lifestyle, vibrant arts scene and storied architecture, all just 30 mins from NYC. Rising prominently in the heart of the village, this striking five-story Victorian stands apart with its ornate balconies, intricate embellishments and commanding vantage points capturing sweeping Hudson River views, all just moments from the energy of downtown Main Street. Built in 2002, the home masterfully blends historic charm with modern construction, evoking the romance of the 19th century while offering the comforts of today. Its whimsical exterior-reminiscent of a refined storybook estate, features distinctive rooflines, turreted forms and sun-drenched windows that pour natural light into its curved interior spaces. Enjoy river, bridge and mountain vistas on the two balconies; ideal for morning coffee as the sun rises over the river, or evening wine under the dancing moonlight. Outdoor living continues with a fenced rear patio and a front garden framed by lush shrubbery, evoking the charm of the English countryside. Inside, the expansive 6, 500+ sq ft layout showcases richly detailed hardwood floors and generously scaled rooms with potential for nine bedrooms. The main living room, anchored by a fireplace, flows seamlessly into a bright and inviting kitchen where arched windows and a central island create a warm yet sophisticated gathering space, fully equipped for both everyday living and entertaining. The upper levels offer five spacious bedrooms, including a distinctive primary suite wrapped in windows along a curved wall, creating a serene, light-filled retreat. Bathrooms throughout are finished with vintage-inspired cabinetry and elegant tile-work, while the primary bath evokes a French sensibility with refined detailing, marble finishes and a spa-like soaking experience. Crowning the home is a fully finished top level, an entertainer's dream, defined by dramatic vaulted ceilings, a built-in bar and direct access to an expansive deck overlooking all of Nyack and the Hudson River. Whether hosting unforgettable evenings under the stars, enjoying cocktails with friends at sunset, or savoring a quiet morning coffee in complete solitude, this elevated retreat offers a truly special vantage point that feels worlds away. What truly sets this property apart-and what makes it exceptionally rare-is the inclusion of not one, but two fully realized lower-level bonus living quarters. Each space features two bonus rooms, a full bath, a summer kitchen, and its own private walk-out entrance, along with dedicated living areas. Whether utilized for extended family, guest quarters, home offices, fitness studios or media lounges, the flexibility is unmatched. For those seeking income potential, these units can offer the opportunity to generate substantial rental revenue, making this not only a lifestyle purchase, but a strategic investment, with a minor zoning change. Properties offering this level of versatility and scale in the heart of Nyack are few and far between. Just one block away, enjoy Nyack's renowned restaurants, live music and weekend street fairs, along with easy access to Memorial Park and Hook Mountain for outdoor recreation.
