As I said in the Garage comments bit, when the Garage is done how about a hangar for Vertibirds? Also, this is really cheaty, but I'd love some beacons that you can place in other custom houses then teleport to them with a aid item.
I don't know what you mean be "without penalty", but here's a killable quest character mod and a move quest items spell. http://www.tesnexus.com/downloads/file.php?id=4146 http://www.tesnexus.com/downloads/file.php?id=11531 The mover requires OBSE, which you can get from here. (which also requires the oblivion patch or shivering isles) http://obse.silverlock.org/
Doesn't appear to be Damarask, it's snowing and there is some ayleid and cheydinhal architecture. Thanks for looking though. I found the house picture at http://www.tesnexus.com/downloads/file.php?id=13354 . I posted a question there, but so far no reply.
