I'll start us off with a few of my own...
First of all, a house I built on a multi-player Yogcraft server. Built in a mushroom biome on a tiny island and around one giant red mushroom out of mainly spruce wood...
The second one is a singleplayer build I did.
Linking to my Tumblr post about it because I took loads of screencaps and commented on them all. I'm not re-posting it all here. x.0;
