Sliding stair drawers require careful planning and accurate execution if you want them to stay level, function smoothly, and seamlessly mesh with under-stair paneling. With this under-stair sliding shoe cabinet, modeling software comes in handy to create a sketch and deliver detailed dimensions.

You’ll need a quality set of shop tools, including a table saw and router, and aligning the drawer slides can be challenging. The finished product is worth the extra effort, with adjustable shelves, inset racks, and a smooth paint job leaving a versatile build with a professional look.

If exposed stairs lead to a basement, you can whip up extra storage with spare materials around the shop. A few cuts of plywood, some supports (ripped 2x4s in this case), and fasteners are all you need for these under-tread storage shelves. Though limited in height and relatively unattractive in their raw form, these are great for hand tools, extension cords, and anything you’ll want readily accessible at the bottom of the stairs.

Modeling software helps create a plan, and with only a few diagonal cuts and some extra support brackets, you’ll have no problem making a functional and fashionable open-shelf system.

Materials: Chipboard, 1×2 pallets, nails, screws, caster wheels
Tools: Saw, drill
Difficulty Level: Intermediate

Smooth pull-out drawers are convenient, offer abundant storage, and hide nicely under the stairs. But ball-bearing slides can quickly become a frustrating project for a novice DIYer, as you need precise measurements and placement for them to stay parallel and work correctly. Rather than fiddle with an overly complicated design, use a set of caster wheels and a simple guide to get similar utility without finesse.

The hidden storage system in these roll-out shelving plans is a clever solution to a tricky problem. Casters allow the shelves to roll out and in with ease. Meanwhile, a simple wooden bracket keeps it in place, so there’s no worry about it disconnecting and being difficult to reinsert into its hole.
