I need help getting this building in ce.

[PreventThis]

I have made this map which is just a start as of now but i keep getting these couldnt update edge errors that i cant seem to fix. can someone please inform me about how i can fix these. ive already redone all the area around the building twice and all of the faces on the building, and it still dont work. I have also read and watched a few tutorials on fixing errors by welding verts and recreating faces, but none of that worked either. here are a few pics. thanks.
