It seems like it's been well over twenty seasons since construction started on the Four Seasons Hotel and Private Residences on the corner of 14th and Arapahoe streets in downtown Denver — but you can watch the tower, billed as the most expensive property ever built in Colorado, go up in twenty seconds on the website. A time-lapse camera recorded the construction from the pouring of the foundation to the raising of the roof, and while the brisk erection speed may entertain promiscuous web surfers, more technically astute architecture lovers can click on the convenient photo-gallery link to access hundreds of construction photographs taken by amateurs and professionals. There is also a heavenly description and handy tutorial on how to live a Four Seasons Life, which only seems fitting after watching life flash before your eyes.
