An utterly singular waterside retreat - part boathouse, part sky-high great room, entirely unlike anything else on the Chesapeake. Some properties defy easy description. 850 Walnut Avenue is one of them. Positioned just steps from the Chesapeake Bay and moments from the Herrington Club and the charming shops and restaurants of downtown North Beach, this idiosyncratic residence turns the traditional home concept on its head - literally and figuratively. Arrive at the property and you are greeted by four drive-through garage bays at street level - two sized perfectly for boats, two for full-size vehicles - allowing you to pull straight through the base of the structure. The entire living space floats above, creating a seamless blend of coastal utility and architectural drama that simply cannot be replicated. Step through the front door and ascend a full flight of hardwood stairs into one of the most breathtaking great rooms in the region. Soaring 20-foot ceilingsdraw the eye upward while an abundance of windows floods the space with natural light from every angle. Suspended ceiling fans circulate the bay breeze year-round, and a classic wood-burning stove anchors the room with warmth and character on cooler evenings. The main level is thoughtfully appointed with generous cabinetry, a panel-front refrigerator, dishwasher, and microwave, a dedicated dining area, powder room, and ample storage throughout. Step outside onto the large deck - an ideal perch for sunrise coffee or sunset entertaining with bay air all around you. Upstairs, two bedrooms and a full bath with tub/shower await, along with a stunning overlook down into the great room below - a vantage point that never gets old. Every level of this home offers a fresh perspective and a sense of being lifted above the ordinary. Steps to the bay. Steps to the Herrington Club. A short stroll to downtown North Beach. And unlike anything else on the market - this is the one you will remember.
