Made this old abandoned building, the building looks photoreal i believe, combined brick and concrete texture and texture painted a mask as a factor, the brick pops out as in the real world and the concrete pops out of  the brick wall however i didn't used displacement in order to maintain it low poly, it just has the bump.

Here is a scene that i made using this building, feel free to ask if you have any questions, 

Here are some rendered images
