This one doesn’t look like a realistic building, but I think that is not important. I particulary like the atmosphere and the white design elements at the base of the building.
The small little edges on top of the base platform are done with a bump map. I did the terrain with the paint deformation tool on an editable poly in 3ds Max. I also added some random pebbles for more realism.
I made the drawing for the building in Sketchup. It’s pretty simple I think.
