I went through every post in this thread and feel my fellow Calgarians have dropped the ball. For nobody has reposted our tallest, grandest, and most audacious proposal.
And with that, I give you the 2,000 foot, $170 million proposal from 1971,
Singer City.
Which, if you can read the print, would have included 1 million sqft of commercial space, 2,500 hotel suites, an international trade centre, and the highest observation floor in the world (in the tallest tower in the world).
My favourite quote in the article, which really symbolizes the spirit of the oil boom:
"Nothing is impossible."
