My First One Command Creation

I made a one command creation for the first time! It is a basic house. Get the command here. Even though it's just a simple house, you can build in it after it creates itself, and you can even create a second house inside the first one! Or you can stack two houses on top of each other! Whether you want a house, or you have some zombies on your back, this house is for you! Simply paste this in a command block, and power it, then you're good! When making this command, I used no generators or anything, just plain old TextWrangler, so don't look at this as junk!
