Office Property For Sale

An exceptional opportunity to own a landmark property in the heart of Kingston’s historic downtown. Built in 1825, The Gildersleeve House is one of the city's oldest surviving residences—an elegant Georgian structure rich in architectural and cultural significance. Positioned prominently at the corner of King and Johnson Streets, this heritage building has been meticulously maintained and currently functions as a high-end commercial office space. The 4,249 sq ft interior was tastefully restored and modernized in 2000, blending original period details—such as intricate moldings, solid wood doors, and a grand front entry—with the functionality of contemporary office design, including multiple private offices, meeting rooms, and a distinguished reception area. A charming third-floor apartment offers added flexibility, perfect as a private residence, guest suite, or executive quarters. Outside, the reconstructed 1890s iron fence frames a manicured front garden, and six private parking spaces add convenience. Zoned DT2, the property supports a wide variety of uses, including residential, presenting the rare opportunity to convert this historic gem back into a premier downtown home. Just steps from City Hall, the waterfront, and Kingston’s best dining and amenities, The Gildersleeve House offers unmatched character, prestige, and potential.
