Situated in the heart of Williamsburg, 401 Graham Avenue is a rare and cherished home, lovingly maintained and preserved by the same family for decades. Legally structured as a two-family residence and currently enjoyed as a single-family home, this three-story property stands as a testament to pride of ownership over the years. Spanning three light-filled levels plus a full basement with finishing potential, this home allows you to move right in and enjoy its old-world charm as-is, layer in your own contemporary touches over time, or reimagine the space entirely to suit your needs. The first level is the perfect gathering space, anchored by an open-plan, Tuscan-style eat-in kitchen with room for a center island or dining table, abundant cabinetry, a breakfast counter, granite countertops, and a stainless steel appliance suite including a dishwasher. The kitchen flows seamlessly into a banquet-size formal dining room, versatile enough to double as additional living space, while a brick paver patio that will transport you to the a Mediterranean villa just off the kitchen offers a peaceful, private spot to relax and entertain outdoors. Upstairs, an expansive living room offers rare flexibility, easily repurposed as a massive primary bedroom. This level also includes a spacious bedroom with two closets and a fully updated bathroom featuring a glass-enclosed windowed shower with high-end brass fixtures and an oversized vanity. The top floor is home to a king-size primary bedroom, an additional bedroom, a home office, and an updated windowed bathroom with a stall shower, ideal for anyone in need of both space and flexibility. Throughout the home, ceramic tile and hardwood flooring, recessed lighting, and decorative fireplaces add warmth and character, while multiple windows bring in natural light and cross ventilation. Thru-wall A/C units keep every level comfortable year-round. Set within one of Brooklyn's most vibrant and sought-after neighborhoods, the location perfectly complements the home's rich history. Step outside to explore Graham Avenue's celebrated local eateries, cozy cafes, independent boutiques, and nearby greenspaces. With the Graham Avenue L train station just blocks away, commuting to Manhattan is swift and effortless. This true neighborhood treasure ready for its next chapter.
