[ Space / Lost and Found ]


Location: Calgary, Canada
Status: Masterplan completed in May 2015 






[ Space / Lost and Found ] is an urban revitalization project focuses on the transformation of Calgary’s existing transportation infrastructures along 9th Avenue business revitalization corridor.
The phrase “lost space” is used to describe any space that remains under-utilized within the urban environment. They might be leftover pieces from a building or a ghost of the planning past. They are part of the public realm, and yet rarely designed to function with social or environmental benefit to the city. With rapid urban growth and shifting industry focus, Calgary’s 9th Avenue streetscape needs to be “transformed” to avoid the formation of “lost spaces,” and to better adapt to the contemporary urban lifestyle. The goal of this project is to come up with a design solution that re-envisions existing remnant public spaces to provide program opportunities, to repair ecological integrity, and to celebrate Calgary’s cultural identity.
