Ask the hardware store to cut your first plywood piece becomes three equally sized pieces with 15 ½” width. You can easily make some cross cuts later on at home. Use the picture to make the cross cuts.
Then, for the second ¾” plywood piece, ask to cut into one 13 ¼” strip and two 15 ½” strips. From these pieces, make the cross cuts as shown in the picture.
The last ¾” plywood piece is to be cut as shown in the picture. Use the larger half as the headboard and the footboard bed panels by cutting it into two. Use the remaining plywood to cut the drawer faces.
Use ¼” plywood piece to cut some pieces as shown in the picture. For two last drawer bottoms, you can make use of the leftover piece of ¾” plywood. Make two pieces of drawer bottoms from those leftover plywood.
Deal with the headboard first. Insert the trims on both top and bottom of the headboard. Do the same step onto the footboard. Secure all joints using glue and 1 ¼” screws.
Insert legs into both sides of headboard and footboard. You can easily install the legs if you use Kreg Jig. Drill some holes onto the sides of the headboard and footboard and attach the legs. For the footboard, leave 1 ½” gap on the panel back as shown in the picture.
Secure all joints using glue and 1 ¼” screws. If you don’t use Kreg Jig, you need to choose appropriate drill bits to drill the holes and determine the depth of the drilling. Then, after the legs are inserted, secure the joints using glue and screws.
Install two bottom supports into the headboard. Follow the direction shown in the picture. Drill some holes before inserting the bottom supports. Secure the joint using glue and 1 ¼” screws.
Install the top frame onto the headboard as shown in the picture. Secure the joint using glue and nails. You can also add some screws to strengthen the structure.
Install the headboard crown using glue and 3” screws. Leave 1” overhanging gap on both side of the frame.
Install the bottom supports into the footboard as like you do with the headboard. Leave 1 ½” overhang on the back side of the footboard panel!
On the back panel, insert two 2×4 spacers. Due to the overhang, the spacers are perfectly fitted. Secure the spacers using glue and 2” screws.
Build the storage drawers using the direction as shown in the picture.
Insert back panel of the storage boxes using glue and nails. Screw the center dividers as well. The back panel is very helpful to maintain everything straight and reduce the drooping.
Cut the leftover plywood pieces to make some blocking to keep the storage drawers up when screwing them into the footboard and headboard. Screw the joints from inside parts of the drawers into the supports and the legs.
Install the cleats onto the back panel of the storage drawers. Leave ¾” space onto the top.
Add some supports onto the center. Make 2×2 legs as in the picture.
Install the slats to place your mattress.
Make the drawers. Use precise measure so that your drawers can slide into the storage boxes perfectly. Make the drawers 1” smaller and 1” shallower than the boxes’ sizes.
Attach the drawers using some drawer slides. Leave 1” gap from the outside for the drawer faces. Adjust the slides of the drawers until you are pleased with how your drawers are open or closed.
Make the drawer faces by firstly attach the hobby stock onto the drawer faces using glue and ¾” nails. Then, attach the faces onto the hobby stock and secure them using glue and 1 ¼” screws.
