I built this villa about a year ago in minecraft, it took my 7hours.
Step 1: The Pool and Backyard
Step 2: The Bedroom
Step 3: The Living Room
Step 4: End
If you want to explore the house by yourself, you can download it here: http://www.planetminecraft.com/project/minecraft-...
I would be happy if you vote for me in the "Minecraft contest". :)
