Our kitchen was getting too cluttered with not enough counter-space, so I decided to make some cheap heavy duty storage shelves.
Total cost was around $55 not including tools. Each of the 4 shelves are 21"x 45" and the assembled structure stands 78" tall.
Step 1: Materials & Tools
I got all necessary materials at Home Depot. Luckily, my local Home Depot cuts all lumber for free which significantly cut down on the total cost of this build. Some lumber yards charge up to 50 cents per cut, so that would have gotten expensive very quickly. I certainly had the capability to cut my own wood, but it is just so much faster and easier to transport in a sub-compact if you get the store to cut it for you.
10 * 8' 2 x 4's @ $2.59 each = $26
1 * 4' x 8' sheet of 1/2" thick plywood = $20-$30
80 * 2.5" exterior screws = $5 (just buy a 1 lb box)
1" finishing nails
Set of drill bits
