Welcome home to 140 Clinton Avenue, a meticulously maintained, ground-up townhouse offering the scale, infrastructure, and ease of new construction, paired with the flexibility of a two-family configuration. Built in 2017 and thoughtfully upgraded since, the home has been primarily enjoyed as a single-family residence while retaining a fully independent garden-level apartment for income or extended living. Designed with intention and maintained to an exceptional standard, every system from mechanicals to finishes is current, efficient, and seamlessly integrated, allowing for a truly turnkey experience. Notably, there is an approved plan for a curb cut, providing the rare opportunity to create a private garage within the basement level. Up the stoop, the parlor level serves as a dramatic open-plan great room, where living, dining, and kitchen spaces unfold with impressive proportions and natural light. The chef's kitchen is outfitted with a full suite of premium appliances, including Sub-Zero refrigeration, Wolf ovens and range, and a Miele built-in coffee system, complemented by upgraded cabinetry and refined finishes. A full wall of accordion glass doors opens to the rear terrace, creating a seamless indoor-outdoor connection that transforms the entire level for entertaining. Radiant heated flooring and integrated climate systems ensure year-round comfort, while a powder room completes the level. The upper level is thoughtfully arranged to provide both privacy and flexibility, anchored by a spacious primary suite with floor-to-ceiling windows and doors, a walk-in closet, and a beautifully finished marble bath. Two additional generously sized bedrooms, each with custom closet systems, share a nicely sized, modern white bath with a window, offering natural light and a clean, timeless finish. Zoned heating and cooling allow for tailored comfort throughout. The garden level is currently configured as a fully self-contained two-bedroom, two-bathroom apartment with its own private entrance, offering immediate income potential or an ideal setup for guests or extended family. A spacious living and dining area flows into a well-appointed kitchen, creating a comfortable and functional layout. Two bedrooms are privately situated within the apartment, while a separate third bedroom and full bath, positioned at the rear with direct access to the garden, are currently incorporated into the main residence as an additional bedroom. This configuration provides excellent flexibility, as the rear suite can be seamlessly reintegrated into the garden level to create a true three-bedroom layout, or continue to function as part of the main home. The apartment operates with its own dedicated HVAC zone, allowing for fully independent use, while also benefiting from the home's overall radiant heating system. The fully finished cellar offers a substantial extension of the home, currently configured as a media and recreation space with extensive built-in storage and a powder room. This level benefits from the same high-quality construction and radiant heating as the rest of the home, creating a versatile environment for entertainment, work, or play. The full-floor roof deck is a true highlight, thoughtfully designed and built out with multiple zones for dining, lounging, and entertaining. Finished with a high-end pedestal system, it functions as an outdoor living room with open exposures and a level of finish rarely found. Throughout the home, a comprehensive suite of upgrades further elevates the offering, including radiant heated flooring throughout, Lutron lighting, Sonos audio, extensive security and camera systems, custom closets, and over $450,000 in capital improvements. The result is a property that delivers not only scale and design, but also a level of infrastructure and ease that is rarely achieved-offering immediate livability with long-term flexibility and income potential.
