Welcome to the fourth annual Inc. World's Coolest Offices. These are some of the most awe-inspiring, spectacular, and just straight-up useful office spaces in the world--and they've all been completed within the past three years.

While you'll notice that a couple of the winners are massive company headquarters, with brilliantly--and subtly--integrated branding, elaborate fixures, and sweeping views, you'll also notice that several of the winners built out their stunning offices on a much more constrained budget.
