Park Lane went vertical on two additional buildings, bringing the total to five now simultaneously under construction.
You can reference the map below and in the gallery below (for the high resolution image) to get an understanding of which buildings are under construction. It's buildings 4a, 4b, 4c, building 3, and building 1A. Wowsers! Check out the photos in the gallery below. I also notated which building is which in the caption of each photo.
