just tried it in the 777 sim...
... and we crashed exactly where they did...
sim visual data base has three low buildings at about 1 mile and we cleared those by maybe 10 feet ....don't know if those exist in the real world.
There's the Air Canada Cargo Facility dead on 1 mile from (normal) 'touch-down' . . .
Others further out are either not directly on flight-line or far enough away to be of no concern . . .
Check here (you can pan and zoom in/out):-
