As Toronto continues to develops at break-neck speed, high altitude office buildings and condos become increasingly associated with materials like glass and steel.

Its stunningly simple lines and shapes, comparable to those of many of our newer sky-scraping structures, shows the beauty that any material can have if moulded skillfully.
