The fantasy of living in a converted industrial space, rich with character and authentic details, will always be a part of urban existence. The clients of interior designer Richard Ouellette and architect Maxime Vandal, founding partners of Montreal-based Les Ensembliers, now have that envy-inducing narrative of their own. Ouellette and Vandal transformed an austere, hard-edged former sugar refinery into a chic three-level, 6,660-square-foot home. “The husband owned the space prior to meeting his wife, so this became about merging their two natures into one space,” Vandal says of the home, a combination of three adjoining apartments. In the living room (this spread and previous pages), soaring ceilings lend a powerful loftlike sensibility, furthered by the all-metal surround of the fireplace and concrete floors. Softer details, such as the custom-designed geometric carpet with splashes of maroon and mauve, as well as the pair of Holly Hunt LaSalle club chairs covered in silk velvet, make for a sophisticated balance of styles. A vintage, abstract Murano-glass buffet, located just off the dining room, serves as a bar. Beneath a staircase, a black stone and malachite Kudu Head sculpture from Jonson Cornell contrasts with Zinc Textile’s wall covering.
