In Vancouver during the 1950s and 1960s, Modernist architectures inspired by Frank Lloyd Wright and fostered by the unique building materials and physical setting resulted in various daring new styles of housing, particularly on Vancouver's ritzy North Shore, featuring open beams, glass walls, and innovative floor plans. Vancouver architect Arthur Erickson, more known for grandiose exercises in institutional concrete such as Robson Square and Simon Fraser University, pioneered the British Columbia version of the "West Coast style", variations of which are also common in Washington, Oregon and California. Erickson-designed houses are prized for their intimacy and taste, as well as their advantageous use of natural settings. A lesser, though much more common, form of Modernist architecture developed during the 1960s was the Vancouver Special, a two-story stuccoed box which took up most of a city lot, and typically featured two suites, one upstairs and one downstairs.
