553 Gilmour Street offers a rare chance to own a true piece of Ottawa's architectural history in the heart of Centretown, just steps from Dundonald Park and surrounded by some of the city's best cafés, restaurants, and everyday amenities. Originally built in 1898, this Victorian residence blends timeless design with an impressive sense of scale, offering nearly 3,000 sq ft of living space across three full levels. The home's wood and brick exterior immediately sets it apart. Inside, a rich collection of period-correct details tells the story of its craftsmanship. Stained glass accents, intricate mouldings, detailed ceilings, and original staircase railings all contribute to a warm, character-filled atmosphere that's increasingly hard to replicate. The principal living areas are expansive and well-proportioned, anchored by a fireplace that adds both charm and function to the main gathering space. With 6 bedrooms and 2.5 bathrooms, the layout offers exceptional flexibility for a variety of lifestyles, whether accommodating a large family, multi-generational living, or those in need of dedicated work or guest spaces. A unique feature of the home is its two staircases, including a "butler's" staircase off the kitchen that provides convenient access upstairs. Each level maintains its own sense of character, with large windows bringing in natural light and highlighting the home's architectural features throughout. The finished basement, complete with hardwood floors, adds additional functional living space, ideal for a recreation area. A detached garage adds everyday practicality, while the central location places you within easy reach of parks, transit, and downtown. Properties of this size and character in such a prime setting are increasingly rare, making this a standout opportunity for buyers who appreciate historic homes with presence, detail, and enduring appeal.
