Moving into a new house, we need quite a few shelving units to store stuff. We don’t have a finished basement, and we haven’t figured out how it would be finished yet, so we need some free standing shelving units that are not attached to the wall, and also have some options to move around later on.
Another reason for the free standing units was because of the flexibility. The storage section of a finished basement is normally not all completed with drywall, part of it will be concrete so it’s a bit difficult to attach something onto.
Step 1: Materials
(6) 2x4x12' Beams
(6) 2x4x7" Vertical supports
(3) 2x4x10' Frame pieces
(2) full sheet 4'x8' 3/8" plywood, plus additional 2'x4' piece (or you can use 1/2' OSB) cut to 2'x8' (actually they will be 23 7/8" x 8') Shelving surface material
3" drywall screws or 3" nails
Some 1 1/4" drywall screws
Drill or impact driver
A hand saw or miter saw / circular saw
The picture is showing my folding sawhorse in use of holding a bunch of 2x materials to make this shelving unit.
Step 2: Dimension
Our basement has 9' ceiling, based on your application, the shelving units could be different than what I have here.
We have a lot of file boxes that will fit into 3’ space when they stack together, so that's what I chose for beam spacing.
We wanted to have the bottom shelf a foot above the ground in case of water heater tank rust out or some other water damage (we all have that experience).
Normal sheet goods from home center comes in 4’x8’ size, so it’s kind of nature to cut them in half – 2’x8’, only make sure to tell the person in the store to count in the width of the saw blade (1/8”), otherwise, you are going to end up with two half sheets that are not the same dimension in width.
