A Google search of 411-415 Garden Drive didn't produce anything from the City of Vancouver Archives, nor any secret lore, but it did produce an okay Google Maps pic (below), which I cropped, else you'd see its tools.
I've never looked closely at this building before, always entering its stores and restaurants from the East Hastings Street side. But after parking near it I was slowed by its Mission Revival form. The clay tile awnings are gone, but you can see their outlines. Same goes for the boards that lie behind its chipped stucco. The newest thing on the building is a painting of a Radio Flyer wagon.
