We have here 10 commercial buildings and 10 residential buildings with median details, in order to be used on distant view or background. Nice for cityscapes, helicopter overflight or a view through a window. Each building is present in the blender file in two options: as a group of meshes and as a unique mesh. We have also the (almost) universal formats: 3ds, obj, dae and fbx. Note that these other formats have slightly less polygons in order to keep files sizes in reasonable values.
