Here is my rendition of the Welsh cottage Bron-Yr-Aur. The cottage was built in the 18th century, and is best known for it's use by Led Zeppelin; whom wrote a song after the house on their album Physical Graffiti.

Although there are no pictures or videos that show the interior of the house, I think I got the look from the outside pretty well. It took about 4 1/2 hours to build (because of the black wool) on a SMP server called Minecrafttunnel. It is completely legitimate. NOTE: I only tried to build the cottage itself, not the surrounding terrain as well.
