Here's some detail on the garage door. As noted above, it's made of coro cut to size, and "prerolled" so that it wants to roll up with the door tracks. The tracks were made out of 2x4 stock, making an L-shape using a half-lap joint, then freehand-routing a groove in them for the door to slide in. Four stabilizer bars of wood, bolted to the coro door, add lateral strength, similar to the struts on a real garage door. There's an extra 2x4 on top in this pic that shouldn't be there thanks to William!
