Presenting 865 Delaware-a sophisticated mid-century townhouse with an adjoining 2-bedroom guest unit, each with its own living area, dining space, kitchen, and baths. This property's versatility is truly unmatched: a cleverly designed, portable hidden bar allows for effortless transformation into a spacious 3-bedroom, 3-bath single-family home. With its highly coveted G-RX-5 zoning, the potential extends even further-offering the opportunity to add three additional stories, making this a strategic investment unlike any other. For those seeking a private sanctuary, the owner's quarters span the space behind and above the guest unit, blending luxury and function. The open-concept living area is designed for effortless entertaining, featuring an illuminated onyx fireplace, Caesarstone countertops, custom Brookhaven cabinetry, premium Dacor appliances, and a hidden cocktail service bar. Ascend the floating walnut staircase, and 22 feet above, you'll find a spacious open office, leading to an oversized primary suite with a European soaking tub, steam shower, walk-in closet, and a conveniently located laundry station. Currently, the lower-level unit operates as a fully equipped income-producing rental property with its own entrance, offering immediate cash flow or conversion to a high-performing Airbnb. Upstairs, beyond the Pella windows of the office, awaits the ultimate retreat-a private 1,250-square-foot deck, tucked beneath a stunning 15-foot arched overhang. Designed for relaxation and entertainment, this outdoor haven features a dining area, lounge seating, and a gas fireplace, all nestled within the serene tree canopy of Sunken Gardens Park. Though just moments from downtown, this property offers a peaceful and quiet setting, making it an ideal residence or investment for discerning buyers.
