The iconic Flat Iron style is easily identifiable by its triangular footprint a flat roof.
The flatiron design originated in New York in 1902 and was popular in North American cities before the First World War. The style was born of necessity as a way of using oddly-shaped parcels of real estate. Because Edmonton had a vast amount of available land, most of which was conveniently laid out in a grid pattern, only one flatiron building was ever built.
