1. Cut joists and end pieces to length and assemble on flat surface. Space joists 13" apart on center.
2. Screw end pieces to the ends of joists with 3" screws.
3. Insure module is square and nail on joist hangers.
4. Bend outside flange of the 2 front corner joist hangers flat against end piece and use 3" screws instead of nails to attach the flange to the end of the front end piece
5. Decking is attached after the module is in place, because you into the 4 x 4 support posts when hanging the module.

See pages 25 and 26 for door and turn landing options.

When attaching a step to a landing made with 2x6s, make the outside joists of the step module 34" long instead of 37 1/2" long. This allows the 34" tread length to be maintained.
