Chimire Plaza (UE4) Anybody know how to replicate this?

What could be the workflow to replicate this animation? I know lighting wise it’s not the best but I feel like this actually utilizes UE4 to its full capacity. There are an abundance of UE4 interior scenes that have incredible lighting but always seem so dead and empty; I wish we could see more of these kinds of projects as these types of scenes are what differentiate UE4 from vray, lumion, etc.
