Thomas Fuller’s Galt Old Post Office on the Grand River is conserved as the heritage core of a branch of the Idea Exchange, which opened to the public July 6th, 2018. ACO Cambridge & North Dumfries sought, unsuccessfully, revision of the design to reduce, especially, visual intrusion of the ultramodern riverfront glass “skirt” and the glass box restaurant, which overhangs the local stone masonry. However, the clock, in its tower with a new copper roof, is working again and as much as possible of the original structure of the post office has been restored. With its children’s discovery centre, teen creative space, maker lab and reading room, the Galt Old Post Office Idea Exchange is in the words of Library Board Chair, Gary Price “A building with innovative technology programs for children, teens, parents and seniors. A true community gathering place for discovery and lifelong learning”.
