Built this huge parking garage based off of a real garage in the Philippines. This garage is very complicated since it has a single, two way, concentric staggered helix ramp. The outer ramp forces cars to loop around the parking bays looking for a spot, while the inside ramps allow cars leaving to just merge on and not make any stops allowing for faster traffic flow. The first two floors are shops, but I didn't do the interior. The garage entrance also cuts through the loading dock of the mall. The helix's do a ful rotation to make it to the third floor where the parking starts.

Here's a video of it. This is where I got the design from:
