I think it's just the gaudy style of the render. The finished built product will probably look more normal.
It's the Frederick Law Olmstead School of Architectural Renders - - - where the renders need to be at least 40% park-like greenery on the building - - - which will never happen in real life.
I can picture the scene now: Manager runs into artist's office "Folks, c'mon, I need you to Olmstead this up, pronto!"
