The Old Galt Post Office project is a major renovation, restoration, and addition to an existing, designated heritage structure in Cambridge, Ontario, Canada. The project adapts the existing facility to accommodate the idea exchange, a progressive ‘book-less’ library program comprised almost exclusively of studio spaces for public creation. The design scheme utilizes material transparency in an attempt to promote views of the historic structure, and to project the life and vitality of this program to the street, the Grand River, and the city beyond.
