This 24-by-16-by-16-inch crate is a manageable first outdoor build: it has a flat bottom, simple butt joints, and enough capacity for gloves, hand tools, or a few bags of potting mix. It is not a waterproof box. Build it in a dry spell, seal the cut ends, and keep it slightly off the ground so autumn rain does not soak the base.

Plan and materials
The finished dimensions are approximately 24 inches long, 16 inches deep, and 16 inches high. Use pressure-treated 1-by-4 lumber for the sides and 1-by-2s for the corner cleats and feet. “1-by” boards are actually about ¾ inch thick; check the actual width before cutting because rough or inexpensive stock may vary.
You will need about five 8-foot 1-by-4 boards, two 8-foot 1-by-2 boards, exterior screws, exterior wood glue, and an outdoor-rated finish. Choose straight boards with no loose knots near the ends. Cedar costs more but is lighter and naturally resists decay; pressure-treated pine is cheaper and durable, though it can be wet and harder to finish evenly. Let treated boards dry until they feel dry and a finish no longer beads on the surface.
| Choice | Best for | Trade-off |
|---|---|---|
| Pressure-treated pine | Low-cost, exposed outdoor use | Can warp as it dries; finish may need extra drying time |
| Cedar | Lower weight and natural decay resistance | Higher cost; softer edges dent more easily |
| Regular untreated pine | A covered porch and a tight budget | Shorter service life if rain reaches it often |
For a first build, a box of exterior-rated 1⅝-inch screws is a practical choice. Coated deck screws are usually sufficient; stainless screws cost more but make sense near salt air or where rust stains would bother you. Do not use drywall screws outdoors: they can snap and corrode.
Tools and safety
A circular saw, drill/driver, tape measure, square, pencil, and two clamps are enough. A miter saw makes repeated cuts quicker, but it is not necessary. Use a basic eye and hearing protection set when cutting. Wear a dust mask when sanding, and follow the lumber label when handling treated wood. Cut it outdoors, collect the sawdust, and never burn offcuts.
Cut list
Measure your boards before cutting. Make these parts from nominal 1-by-4 stock, assuming each board is about 3½ inches wide:
Four side boards, 24 inches long; four end boards, 14½ inches long; and four bottom slats, 14½ inches long. The end and bottom measurements fit between the long sides or end cleats, respectively. From 1-by-2 stock, cut four vertical corner cleats, 14½ inches long, and two feet, 14½ inches long.
Stacking two side boards makes each wall about 7 inches tall. The corner cleats extend the full wall height, holding the boards together from inside. If your stock is wider or narrower than 3½ inches, the crate’s height changes, but the listed lengths still work with this arrangement.
Build the crate
1. Cut and inspect. Cut the parts to length and square the ends. Lay matching pieces side by side; if one is noticeably bowed, use it for a shorter part or replace it. A slight bow is manageable, but forcing a badly twisted board into a box can pull the corners out of square.
2. Assemble the long sides. Place two 24-inch boards edge to edge. Set a 14½-inch cleat at each end on the back, flush with the board ends. Drill pilot holes through the boards into each cleat, then drive two screws per board at each end. Keep the screw centers roughly ¾ inch from board edges to reduce splitting. Repeat for the other long side.
3. Join the ends. Stand the long sides upright and fit two 14½-inch end boards between them at each end, one above the other. Drive two screws through the end boards into each corner cleat, using pilot holes. Check that the crate is square by measuring diagonally from corner to corner; the two measurements should match within about ⅛ inch. If they do not, shift the frame gently before adding the bottom.
4. Fit the bottom. Turn the crate upside down. Screw the two 14½-inch feet beneath the long sides, near the ends, leaving the middle open for drainage. Lay the four bottom slats across the feet with roughly ⅜-inch gaps between them. Secure each slat to both feet with one screw at each crossing. The gaps let rain drain; a solid plywood bottom traps water and is more likely to swell or rot.
5. Sand and ease edges. Break sharp corners with 80- or 120-grit sandpaper. Sanding treated lumber creates dust, so work outside and wear a mask. Do not spend time making rough outdoor stock furniture-smooth; concentrate on splinters and edges people will touch.
Weatherproofing and placement
Apply an exterior-rated penetrating stain or water-repellent finish according to its label, including to exposed end grain and the cut ends around the base. End grain absorbs water quickly, so skipping it is a common reason a crate fails first at the corners. A clear exterior penetrating finish preserves a more natural look but needs periodic renewal; a pigmented stain usually gives better UV protection. Neither turns the crate into a sealed waterproof container.
Put the crate on pavers, a porch, or another draining surface, not directly on soil or wet leaves. Leave a little space behind it so air can circulate. Avoid storing paper bags or anything that must stay dry through heavy rain. Check the screws and finish each spring; tighten loose fasteners and recoat when water stops beading on the surface.
Common first-build mistakes
The most frequent problems are splitting ends, a racked frame, and a damp bottom. Pilot holes reduce splitting, especially in dry cedar or near board ends. Checking the diagonal measurements before installing the slats catches a crooked frame while it is easy to correct. Finally, drainage gaps and feet matter more than a thick coat of finish: a crate that stays wet underneath will deteriorate even if its sides look well protected.
