Hi there,

 

unfortunately, blocks of floating houses are a fairly common temporary autogen display "hiccup" in both FSX and P3D. In most cases you can return the floating buildings back to the ground during your flight: either select World > Scenery Library and then simply click on "OK" or assign a key combination to the "Refresh scenery" event in the Options > Settings > Controls menu (Buttons/Keys tab); I use Ctrl-Shift-S but any unassigned combination will work.
