A rare convergence of historic soul and modern engineering, this architectural masterpiece arrives on the market for the first time in 27 years. Situated in the prestigious Golden Triangle on an exceptionally deep lot, the residence sits just 100 meters from the Rideau Canal-a UNESCO World Heritage Site. Meticulously re-imagined as a sun-drenched sanctuary, this historic gem honours its heritage while embracing a bold, contemporary design. The home's centrepiece is a spectacular open staircase spanning three levels, framed by triple-pane windows that summon light from every direction. From soaring ceilings to curated finishes, this 4-bedroom, 3-bathroom residence reflects a commitment to quiet, sophisticated living. The experience begins in a marble-tiled foyer leading to expansive living spaces designed for grand-scale entertaining. The custom kitchen strikes a flawless balance between sleek modernism and industrial edge, featuring high-end appliances and a granite island. This culinary hub flows into a family room addition that opens to a private deck and a lush, Welwyn Wong designed garden. This deep outdoor oasis is a rare find, featuring mature trees, vibrant plantings, and a gas fire pit perfect for evening gatherings. Upstairs, the primary suite is a true retreat, boasting a newly updated ensuite and a private balcony overlooking the serene grounds. A versatile second room on this level, also with a private balcony, adapts as an executive office, bedroom, or yoga studio. The third floor offers two additional bedrooms-one a full suite with its own balcony. Below, the lower level provides rare future potential with high ceilings and a pristine, dry environment. Crowned by a new metal roof, rarely does a property of this scale and integrity become available. This is a once-in-a-generation opportunity steps from Parliament Hill, iconic landmarks, Lisgar Collegiate, and the University of Ottawa. This is urban luxury at its finest. (id:2493)
