In 1955, six architects with strong personalities and a variety of backgrounds founded the firm of Affleck, Desbarats, Dimakopoulos, Lebensold, Michaud & Sise. In the 1970s, the firm operated as Arcop. Throughout its long history, the firm has had a strong influence on architecture in Quebec and across Canada. In 2014, six architecture studios joined to Architecture49. The new firm combines the experience and reputation of Arcop, AE Consultants, North 46, PBK, Smith Carter and WHW Architects and has over 300 professionals across Canada. The Montreal office of Architecture49 stands out for its extensive experience in managing large- and small-scale projects and executing complex projects, particularly in the rehabilitation of large patrimonial buildings and in the hospitality sector.
