Modular 2x4 Garage Shelving Plans PDF - 96" x 24" x 84" Heavy Duty Storage Shelf Woodworking Plan with Cut List, Instant Digital Download
A 14-page printable build plan for a modular garage shelving system made entirely from 2x4 lumber and 3/4" plywood. One bay finishes at 96" wide x 24" deep x 84" tall with four shelf levels (deck tops at 6", 32", 58" and 84"), 21-3/4" of clear height per level and a 1-3/4" floor gap so nothing sits on a wet slab.
The point of the plan is that bays gang together and share posts. A single bay needs 4 posts; three bays ganged need 8 instead of 12, and every shared post gets a 12" splice cleat front and back at every level - cut free from the post offcuts. You can add a bay a year later without unscrewing anything.
What is in the plan
- Full cut list with every part in inches and millimetres
- Materials list per bay: 15 x 2x4x8 studs and 2 sheets of 3/4" plywood, with zero deck waste
- Lumber cut-layout diagram, front and side elevations, shelf-level plan, shared-post splice detail and a ganged three-bay run drawing
- 12 numbered assembly steps
- Hardware and screw counts (64 + 48 x 3", 136 x 1-5/8", anchors, glides)
- Sizing guidance for a narrow 16"-deep variant, a 700 lb/shelf heavy-duty variant and a freestanding variant
- Five common mistakes specific to this build, plus finishing and maintenance notes
- A load-ratings table showing where the 300 lb per shelf rating comes from - deflection, bending stress, post compression and shared-post bearing all shown against their limits
Skill level: Beginner to Intermediate. First bay takes roughly 3-4 hours; each bay after that about 2 hours.
