DUBBELDAM Architecture recently completed a residential project for a young couple in Toronto, Ontario, Canada. The house was called Annex because it originally consisted of two volumes. The new interiors feature an open floor plan throughout, the most notable design feature being a large wooden volume that hides ductwork, storage and a bathroom. On the outside, it is detailed with wood, clear and translucent panels and includes built-in seating flanking the entrance to the dining room. Upstairs, the master bedroom features a soothing gray color palette and minimalistic design, with a comfortable seating area bathed in sunlight. Also on the third floor, an en suite spa-inspired bath includes a stand-alone tub and a glass shower, as well as a walk-out wooden deck.
