Based in Toronto, architectsAlliance (aA) thinks and works at a variety of scales. The practice's award-winning projects in Canada, the United States and Europe range from individual academic buildings to entire campuses, from private houses to large-scale residential developments, and from individual buildings and public spaces to mixed use developments that transform an entire precinct. While the practice's portfolio includes many individual schemes, it is aA's contribution to the intensity and vitality of cities that is of particular interest. Each of the practice's architecture and urban design projects is a conscious act of city building, articulating a compelling and appropriate response to context; a convincing and urbane response to density that enriches both the public realm and the individual's experience of urban life.Like the urban landscape, aA and its projects are 'Work in Progress.' The first full study of the practice will feature more than 20 designs and completed projects, including the Terrence Donnelly C entre for Cellular and B iomolecular Research for the University of Toronto, the Brock University Cairns Family Health and Bioscience Research Complex, student housing for Toronto's York University, the renovation and expansion of the Canadian Chancery in The Netherlands, the North Point residential development in Cambridge, Massachusetts, the Athletes' Village for the 2015 PanAm / Parapan Games, and many of the practice's residential schemes that are playing a major role in the current evolution of Toronto's cityscape.
