Step1
Make these cuts:
Plywood: 4 pieces @ 5 inches x 68 1/2 inches
2 pieces @ 21 inches x 68 1/2 inches
10 foot planks:
5 pieces @ 50 inches x 5 1/2 inches
4 pieces @ 2 inches x 4 1/4 inches
8 foot planks:
4 pieces @ 80 inches x 5 inches
3 pieces @ 68 inches x 5 inches
7 pieces @ 46 1/2 inches x 5 inches
1 piece @ 46 1/2 inches x 3 1/4 inches
4 pieces @ 14 inches x 5 inches
4 pieces @ 77 inches x 2 1/2 inches
4 pieces @ 19 inches x 2 1/2 inches
2 pieces @ 72 inches x 1 inch
20 pieces @ 9 inches x 1 inch
Step2
Rout. Use a straight 1/4 inch bit. Set it at 1/4 inch deep. On the 80 inch x 5 inch pieces rout the center of one long edge leaving 5 inches at the top and 7 inches at the bottom. On all but one of the 46 1/2 inch x 5 inch and 14 inch x 5 inch pieces rout the center of one long edge leaving 5 inches in the middle. On the 68 inch x 5 inch pieces rout the center of both long edges.
Step3
Build the top and bottom. Attach four 46 1/2 inch x 5 inch and the 46 1/2 x 3 1/4 inch piece together using pocket screws. You will make a platform 46 1/2 inches x 23 1/4 inches. This is your bottom. Attach the five 50 inch x 5 1/2 inch pieces using pocket screws. This is your top.
Step4
Build the doors. Span two 77 inch x 2 1/2 inch at the top and bottom with 19 inch x 2 1/2 inch pieces. Center a 72 inch x 1 inch piece inside the frame and attach. Evenly space five 9 inch x 1 inch on either side of the 72 inch piece, creating six openings on both sides. Repeat for the other door.
Step6
Here is an example of the side.
Build the sides and the back. Span two 80 inch x 5 inch pieces using a 14 inch x 5 inch piece. Make sure it is flush with the top. And make sure all routed edges are facing in. Center a 68 inch x 5 inch piece and attach. Slide two 5 inch wide plywood pieces into the routed slots. They will hang past the 68 inch piece by 1/4 inch. Attach another 14 inch x 5 inch piece at the bottom of the plywood pieces, routed side in. When it is in place, it will be 2 inches above the bottom of the 80 inch pieces. Do the same thing using the other plywood pieces and the 46 1/2 inch x 5 inch pieces.
Step7
Attach the sides and the back. Use the unrouted 46 1/2 inch x 5 inch piece as a spanner flush with the front and top.
Step8
Attach the bottom and the top. The bottom fits inside the frame and should be 2 inches off the ground. The top will over hang all edges. Make sure the overhang is equidistant.
Step9
Attach the 2 inch x 4 1/4 inch below the bottom make "L"s with the bottom of the 80 inch pieces.
Step10
Paint or stain all surfaces (including the closet rod if it is wood. Apply at least two coats of lacquer.
Step11
Attach the closet rod hardware. Make sure you will have enough room to hang clothes on both levels.
Step12
Cover the openings in the door by attaching rice paper from behind. Trim the paper so that it does not overlap.
Step13
Attach the hinges so that the doors will be 2 inches off the ground and 1/4 inch below the top.
Step14
Attach door handles or pulls.
