Offered for only the second time since the 1950s, The John Patterson house is a landmark Hamilton mansion occupying a commanding corner at James South and Young. Known for its distinctive turret and imposing proscenium porch, this remarkable property is steps to St. Joseph's Hospital, the Hunter Street GO station, the Augusta Street restaurant district, the downtown core, major transit, restaurants, offices, and ongoing development. The location is unparalleled for exposure, appreciation, and access. Thoughtfully converted over time into a remarkable mixed-use building, it now offers a rare blend of heritage architecture, diversified income, and deep pride of ownership. The lower level fronts at grade onto Young Street and is home to two exceptional hospitality spaces, including a celebrated pizza shop and a beautifully designed dining room with a major recent high-end build-out. The sprawling main floor is a stunning professional office suite with private offices, open work areas, large kitchen, a spectacular boardroom, coffered ceilings, leaded glass, rich woodwork, and a grand entry foyer. The upper levels are equally memorable. The second floor is an elegant apartment with soaring ceilings, generous principal rooms, beautiful mouldings, abundant natural light, and exclusive rooftop patio access. The third floor has a distinctly urban, character-filled feel, with a skylit kitchen, spacious living area, large bedroom, and a spectacular turret room with dramatic windows and soaring ceiling height. Meticulously maintained, extensively updated, and rich with original detail, this is not just another mixed-use asset. Solid brick construction, slate roof, copper eaves/downspouts, rare on-site parking for up to 12 vehicles, and excellent tenants throughout make this a unique opportunity. This is a true Hamilton trophy property - a piece of the city's architectural fabric.
