2800 SQFT OF URBAN LIVING SPACE + A PRIVATE TERRACE OF 1800 SQFT. Architectural masterpiece signed by internationally acclaimed Architect Alain Carle, PH4 on 1625 Clark was the recipient of two Grand Prix Du Design. Historical building part of Montreal's heritage, the building was transformed into luxury urban condos. Carle aestheticized the old charm by adding modern architectural elements by relying on the contrasts of black lacquer, exotic wood and raw concrete. The star of this exquisite penthouse is undoubtedly the steel-framed staircase wrapped in a black shell that opens like an orange peel and allowing the IPE wood steps to flow.
