Because everybody needs a Creeper Shelter for emergencies. (Note: chests aren't stocked. You will need to stock it with whatever provisions you believe necessary)

Outside: Half Drum shaped shelter built out of obsidian with two steel doors, one on either side, and four buttons to open each door from the outside.

Inside: 3x4x3 living space with two beds, two chests, a crafting table, and furnace. Lit by four tourches one in each corner. Two buttons to open each door. Built for two but can be customized on the inside. Tested and proven to stay safe against a TNT detonation. Edit: Just keep alot of iron doors on hand... I suffered a major creeper attack and the extra doors or blocks come in handy to quickly close that door back up if it gets blasted off.

Also using a "Simple Craft" texture pack... I forgot who's, sorry, let me know and I'll put up proper linkage.
