Easiest way to make a house:
1: Go to bricks, select a 1x1x5, a 1x4x5, and an 16x16 baseplate.
2: Do each wall in this order: (Starting from a corner, going from left to right)
1x1x5, 1x4x5, 1x1x5, 1x4x5, 1x1x5, 1x4x5, 1x1x5.
3: Repeat for all walls.
4: Finish with either a flat baseplate roof, or a pointed roof, and make a nice paint finish.
Ephi learned me this a while back.
