The Royal Bank of Canada's historic Montreal headquarters was once the tallest skyscraper in the country, built in 1927. But the bank abandoned the grand space in 2010, leaving behind a decaying neoclassical masterpiece with 50-foot ceilings, brass chandeliers, and marble floors. (And to think, Montreal is now building stuff like this.)

Now the building has a second life, after being repurposed by Crew, which hired architect Henri Cleinge to turn the former bank into a cafe and co-working office featured recently in The Spaces.
