Can I suggest you take a look at Branchscape on the Escapecraft server? It's a multiplayer city where every house is a tree.
Oh and it's pretty much completely legit too if that is necessary.
Video tour (youtube broke on it and the last 3 mins are black nothingness)
Giant photo album to show that I'm not joking.

Escapecraft forum's thread for this town. Contains all needed details if you wish to see it for yourself Doc Strangelove.
(Warning. May or may not be 101 pages long, however it is the longest thread on the Escapecraft forums so...)

I'm not trying to advertise with this I just simply thought that a gigantic multiplayer city like this was superior in all aspects to "Slightly Interesting Minecraft House #34532" which is what I am afraid this gallery apeared like to me.
(Personally, normal houses like these are overrated. I build giant volcano lairs and hide in the sizzling ooze protected by nothing more than ingenuity and glass.)
