Sandrine's classic "bowling alley" style Montreal apartment — long and narrow, a hallmark of the city's older buildings — is a masterclass in intentional design on a budget. Applying her sustainable fashion background to her interior styling, she turned an unused closet into a hidden home office and built a custom mid-century inspired wood accent wall, all furnished exclusively with thrifted and up-cycled second-hand finds. Privacy curtains replace traditional doors as a clever space-saving hack, while original moldings, high ceilings, and a classic clawfoot tub preserve the apartment's historic charm.
