This is my latest architectural work in UE4.
It is a 3 bedroom bungalow with garden. There is also some sort of interactivity - you change facade materials as well as open/close the entrance door. There is also pause menu and floor plan in the menu section.
The interior lighting is adjusted by Post Process Volume with different settings than exterior (indirect lighting is set to 2.0).
