A wall of millwork does a lot here, from storage and display to a built-in bench tucked right into the wall. It gives the dining area its own identity while maintaining an open connection to the entry hall, kitchen and living room.

When architecture frames nature this well, the view becomes the artwork. Final stages on this light-filled, modern space - calm, refined, and almost ready.

Set along the Rideau River, this renovation brings calm, clarity, and quiet luxury to a once traditional home. In the primary suite, a pair of his-and-her walk-in closets leads to an ensuite shaped through intentional material mixology - natural stone, warm oak, brushed bronze, and sculptural lighting.
The palette plays with the raw and refined, creating textural richness and an immersive spatial narrative that feels serene, modern, and timeless.

Where day meets night - a penthouse of polished light and moody shadow, designed for both calm mornings and vibrant nights.

_
Once an office space, this two-level penthouse transforms a former office floor into a home of contrasts — bright and polished above, with glossy tiles and sweeping city views; moody and tactile below, with concrete, leather, and dark finishes shaping a private retreat for leisure and late nights.
