Before & After: An Old Montreal Apartment Embraces Sharp Contrast—and a Surprise Sauna

Designer Louis Béliveau of La Firme embraced the lack of light in this part of the apartment, underscoring it with dark finishes, like the one-by-one-inch Daltile on the floor. A mirrored wall catches some sun from the living room windows. "From a design perspective, mirrors are a magic trick," says Béliveau. "They’re not too expensive and they basically double up the space, and bounce back any light." The open door leads to the hall bathroom.
