A porch storage bench gives coats, boots, hats, and gloves a dedicated landing spot without taking up much floor space. This version is a straightforward weekend project for a beginner with a circular saw or table saw. It is sized at roughly 42 inches wide, 18 inches deep, and 20 inches high—large enough for two adults to sit on while putting on boots, but compact enough for most entry porches.

The design uses a plywood box, a hinged seat, and a removable boot tray. Plywood is more stable than wide solid boards, and the closed box keeps coats and accessories out of sight. If your porch is exposed to rain, build the bench under cover and finish every edge carefully; this is outdoor furniture, but it is not a substitute for weatherproof construction.

Materials and Tools

Use 3/4-inch exterior-rated plywood for the main box. Cabinet-grade plywood is easier to finish, but regular exterior plywood costs less and is adequate when its exposed edges are sealed. You will also need a 1×2 or 1×3 board for face trim, a 1×3 or 1×4 board for the legs and base, exterior wood glue, 1 1/4-inch and 2-inch exterior screws, and two or three 2 1/2-inch butt hinges.

A circular saw and straight-edge guide is enough for the cuts. Add a drill, countersink bit, tape measure, square, clamps, sander, and a 1/4-inch round-over bit if you have a router. A dust mask and eye protection are not optional when cutting plywood.

Material choice Advantages Drawbacks
Exterior plywood Stable, affordable, strong box construction Edges need sealing and may need more sanding
Cabinet-grade plywood Smoother faces and cleaner edges Costs more; still needs a durable finish
Solid pine boards Easy to find and simple to trim Can cup, dent, or open joints as humidity changes

Cut List and Basic Layout

For the 42-by-18-by-20-inch bench, cut the following from 3/4-inch plywood:

  • One top: 42 by 18 inches
  • One bottom: 40 1/2 by 16 1/2 inches
  • Two sides: 18 by 18 inches
  • One back: 40 1/2 by 18 inches
  • One removable divider: 16 1/2 by 16 inches

The bottom fits between the sides and front and back panels. The top overhangs the box by approximately 3/4 inch on each side and at the front. If you want a different width, keep the 3/4-inch plywood thickness in mind when calculating the bottom and back dimensions. Measure the actual plywood before cutting; nominal material and shop-cut panels are not always exactly 3/4 inch thick.

Build the Storage Box

Start by sanding the plywood faces with 120-grit paper and breaking the sharp edges. Apply glue to the bottom-panel edges, position the side panels flush with its ends, and clamp the assembly. Drill pilot holes and drive 1 1/4-inch screws every 6 to 8 inches. Keep the screw heads slightly below the surface, but do not drive them so deeply that the plywood face tears out.

Add the back panel next. Check the box for square by measuring both diagonals; they should be within about 1/8 inch of each other. If they are not, push the box into alignment before the glue sets. The back is important because it prevents the bench from racking when someone sits down.

Install the divider about 20 inches from one side, or center it if you prefer two equal compartments. A divider helps support the seat and stops boots from sliding into a single messy pile. Make it removable with screws driven through the bottom and seat support, so you can clean the interior later.

Add the Base and Hinged Seat

Cut four legs from 1×3 or 1×4 stock. Make them 3 1/2 inches high, then cut front and side base rails to fit between them. Glue and screw the rails to the legs, forming a low platform. Attach the platform beneath the box with 2-inch exterior screws. Raising the box keeps boots above minor porch water and gives the bench a lighter appearance.

For extra strength, add a 1×2 cleat under the front edge of the seat and another along the back inside edge of the box. The seat is the part most likely to fail if it is only screwed into plywood edges. A cleat spreads the load and gives the hinges better screw holding.

Mount the hinges to the back cleat and underside of the top. Use three hinges for a 42-inch seat if the bench will receive regular use. Leave a small, even gap at the back so the lid opens without rubbing. Test the lid before applying finish, and add a chain or lid stay if children may lift it. A heavy seat can pinch fingers when it drops.

Fit the Boot Tray and Finish

Use a plastic boot tray inside the lower compartment rather than trying to make the plywood floor waterproof. Choose one no wider than about 16 inches and trim the divider position if necessary. A plastic boot tray is inexpensive, removable, and much easier to wash than a permanently sealed wooden pan.

Fill screw holes with exterior filler, sand to 150 grit, and seal all plywood edges with two coats of exterior primer. Pay special attention to the bottom, end grain, and screw holes. For a painted bench, use exterior acrylic paint over primer. For a natural look, apply an exterior spar urethane or porch-rated stain according to the label. Do not use ordinary interior polyurethane on a damp porch; it can peel after repeated wetting and drying.

Install two or three coat hooks on the back or nearby wall, not on the hinged lid. Hooks mounted to the lid add weight and can make the hinges sag. If you need organized storage inside, add a few canvas storage bins sized to the compartments.

Safety and Seasonal Maintenance

Anchor the bench to the wall if it will sit where children can climb on it. Locate studs, then drive screws through the back into at least two studs, using washers if the holes are oversized. Never rely on drywall anchors for a climbable bench.

Before winter, inspect the finish for cracks and reseal exposed edges. Empty the boot tray regularly so trapped grit does not hold moisture against the plywood. In spring, check the hinges and base for loosened screws. If the bench repeatedly gets soaked, move it under cover or replace the plywood with a more weather-resistant material; no finish will make an indoor-grade bench permanently rainproof.
