SOE has released the third in a line of recent seven-year-anniversary gifts for SWG players, and it's a schematic for some fun housing: a Wookiee treehouse. It's a single-use item, of course, but it will net you a pretty impressive new residence.
The Wookiee treehouse takes up two lots, gives you 200 storage, and makes quite a statement on the surrounding landscape. If you'd like to check it out more closely, you can find a list of materials and several screenshots on the official SWG forums.
[Updated to clarify that this is an anniversary gift, not a veteran reward!]
