A really simple house that looks good and is usefull
Step 1: Foundation
This is simple, dig out a 3x3 space in the ground with one extra block sticking out of the side like so.
Step 2: Base and Walls
Fill the foundation with a block of your choice, I used stone slabs. Then, Start the walls by surrounding the base with any block (I used sandstone for that Roman look) with one small opening for a door.build second layer just like the first one only with a hole in the wall in line with the door for a window. keep repeating until the walls are four blocks high.
Step 3: Roof
To replicate a Roman Villa, simply cover the roof with sandstone and make it flat like I did in the picture.
Step 4: Your Done!!
Now enjoy your house and stop zombies from eating your brains!!
