No matter if I export as .obj or .fbx.
Here is it in .blend

I've scaled down your object in order to see the problem: 1 is your building, 2 is the landscape you show, which is far away and much bigger:
What you can do is switch to Edit mode and X-Ray mode (AltZ), select the building with the lasso or the box selection tool, inverse the selection with Ctrli and remove the vertices with X, or simply separate the building with P (Separate) > Selection.
