The cover story for the October 2006 "Collector's News" magazine features a Tolkien collector (unnamed) who has built an entire house (complete with circular doors) to house his collection of books and other materials.

There is an inaccuracy in the article - the original collector first attended a Tolkien Society sponsored event in 2005, but the article author implies that this was the first time the Tolkien Society sponsored an event.
There are a few pictures of the house (very well constructed and very beautiful, but above ground and so not a true Hobbit abode), but only one interior shot that only shows a small handful of items from his collection in the background.
Still, enough to make this collector quite jealous!
