Conceptualized by Canadian designer Anne Sophie Goneau, the elegant, 1,035-square-foot Espace Panet is located on the third floor of a 1910 triplex building in Montreal, Canada. In an awe-inspiring renovation, the compact apartment was transformed into an open, light-filled living space. The challenge of the remodel was to provide division between each function while maximizing space, respecting the original structure, and allowing light to pass between rooms. An interior, custom-made steel staircase with floating treads and a minimal handrail, lead to the roof deck above.
