Build steps

  1. Mark 10 post positions in two rows 9 ft apart, with the posts every 58 in along the length. Check square by measuring both diagonals. Dig each hole 36 in deep.
  2. Set the 6x6 posts plumb in gravel or concrete, the front row 18 in taller than the back, and brace them.
  3. Bolt two 2x6 beam boards on edge over each row of post tops with 1/2 in carriage bolts, with the joints staggered over different posts.
  4. Cut the 6 rafters with plumb cuts at 9.5° on both ends and set them on the beams, 48 in on center.
  5. Lay 6 purlins flat across the rafters and screw down the 11 metal panels, lapping one rib.
  6. Bolt three rows of 2x6 girts to the outside of the back posts, at 24, 54 and 84 in, and screw the plywood over them.
  7. Spread 4 in of gravel on the floor and set the equipment under the roof.
