Located on a quiet, tree-lined block just moments from Riverside Park, 312 West 103rd Street is a beautifully proportioned 19-foot-wide townhouse that combines classic Upper West Side architecture with an ideal layout for both living and income potential. Measuring approximately 4,506 interior square feet, with an additional 1,000-square-foot cellar and outdoor spaces, the home offers exceptional scale, natural light, and preserved historic character. Designed in 1889 by architect Edward L. Angell for developer Robert B. Baird and completed in 1891, 312 West 103rd Street was conceived as part of a pair of distinguished Upper West Side townhouses. The residence reflects Angell's characteristic blend of Romanesque Revival and Queen Anne design, with decorative architectural details and stained-glass elements that continue to define the home's historic character today. Configured with a spacious owner's triplex above two garden-level rental apartments, the property provides an outstanding opportunity to enjoy townhouse living while benefiting from stable income. The two rental units together generate approximately $4,000 per month, nearly offsetting the home's $2,266 monthly taxes, making the residence remarkably efficient to carry. The owner's residence spans three floors and is filled with extraordinary natural light throughout. The home retains many beautiful original details, including decorative fireplaces, parquet floors, and charming stained-glass accents that speak to the townhouse's historic character, while modern upgrades such as central air conditioning provide contemporary comfort. Upon entering the owner's unit on the parlor floor, you are greeted by a formal dining room centered around a remarkable stained-glass window overlooking the garden, which frames greenery and fills the room with warm southern light. This space creates a serene backdrop for dining and entertaining. Just beyond, the updated kitchen is thoughtfully positioned with convenient access to the garden below. The third floor offers one of the home's most beautiful spaces. At the front of the house is a gorgeous full-width living room, bathed in natural light from large south-facing windows and highlighted by original details and a decorative fireplace. Adjacent to the living room is a separate office, perfectly suited for working from home or quiet study. At the rear of the floor is the primary suite, which includes a dressing room, full bath, and access to a private terrace overlooking the garden. The fourth floor offers three additional bedrooms, along with a full bath and laundry, providing a practical and comfortable layout for family, guests, or additional workspace. Just steps from Riverside Park, this location offers one of the Upper West Side's most treasured green spaces, with easy access to riverfront paths, playgrounds, and recreation while remaining close to neighborhood restaurants, shops, and transportation. 312 West 103rd Street presents a rare opportunity to own a wide, light-filled Upper West Side townhouse that combines classic architectural details, generous scale, and the financial benefit of income-producing apartments.
