I have the Ikea House. Not sure what version it was from, but I'm pretty sure it's not available anymore and it is kinda old.
EDIT: It is old. I joined in v9, and one of the first things I remember was that I opened the server list in the demo, and saw a server hosted on "Ikea House v2" and getting mad for not having the game yet because I wanted to see it. Good times...
