How To Build An Outdoor Storage Bench Seat

An outdoor storage bench seat offers a practical and aesthetically pleasing solution for maximizing space and organization in outdoor areas. It serves a dual purpose, providing comfortable seating while offering concealed storage for gardening tools, pool equipment, toys, or other outdoor essentials. Constructing such a bench involves careful planning, selecting appropriate materials, and following a detailed construction process. This article outlines the steps required to build a durable and visually appealing outdoor storage bench seat.

How To Build An Outdoor Storage Bench Seat

The construction of an outdoor storage bench seat is a manageable project for individuals with basic woodworking skills. Prior to commencing the build, a design must be established, including the dimensions and style of the bench. This design should consider the intended location of the bench, the desired storage capacity, and the overall aesthetic of the outdoor space. Accurate measurements will be critical throughout the construction process.

Material selection is paramount, as the finished product will be exposed to the elements. Pressure-treated lumber is the most commonly recommended material for outdoor furniture. It is resistant to decay, insect infestation, and moisture damage. Alternative wood options include cedar, redwood, and teak, all of which possess natural resistance to weathering. Stainless steel or galvanized hardware should be used to prevent rust and corrosion. Additionally, consider the type of finish or sealant to be applied to protect the wood from UV damage and moisture.

The following steps will guide the construction process, ensuring a sturdy and functional outdoor storage bench seat.

Planning and Preparation

The initial phase involves meticulous planning and preparation. This includes determining the dimensions of the bench, creating a detailed cutting list, and gathering all necessary materials and tools. Safety considerations should be paramount throughout the project. Wear safety glasses, gloves, and a dust mask when cutting and sanding wood. Ensure ample workspace and proper ventilation.

Determining the dimensions of the bench is crucial to its functionality and aesthetic appeal. Consider the available space in the intended location and the desired seating capacity. A typical bench height ranges from 16 to 18 inches, while the depth of the seat can vary from 18 to 24 inches. The length of the bench can be customized to fit the specific needs of the user.

Based on the chosen dimensions, create a detailed cutting list that specifies the number and size of each piece of lumber required. This list will serve as a guide during the cutting process and ensure that all necessary components are readily available. Include dimensions for the frame, seat supports, side panels, backrest (if desired), and lid supports.

Gather the following tools and materials before commencing the build:

Pressure-treated lumber (or chosen alternative)
Stainless steel or galvanized screws
Wood glue (exterior grade)
Measuring tape
Pencil
Circular saw or hand saw
Drill with drill bits and screwdriver attachments
Sander with sandpaper (various grits)
Clamps
Safety glasses
Gloves
Dust mask
Level
Wood sealant or stain (optional)

With the planning and preparation complete, the construction process can begin.

Constructing the Frame

The frame forms the structural foundation of the bench. It provides support for the seat, sides, and backrest (if included). Accurate construction of the frame is essential for the overall stability and durability of the bench. The frame typically consists of four legs, two side rails, and two front and back rails.

Cut the lumber according to the cutting list for the legs, side rails, and front/back rails. Ensure that all cuts are accurate and square. Use a circular saw for long, straight cuts and a miter saw for angled cuts (if desired). Sand all cut edges to remove splinters and ensure a smooth surface.

Assemble the frame by joining the legs to the side and front/back rails. Apply wood glue to the joints before securing them with screws. Use clamps to hold the pieces together while the glue dries. Ensure that the frame is square by measuring the diagonals. The diagonals should be equal in length. Adjust the frame until it is square before fully tightening the screws.

For added strength, consider adding corner braces to the frame. These braces provide additional support and prevent racking. Cut four triangular pieces of lumber and attach them to the inside corners of the frame using glue and screws.

Once the frame is assembled and the glue has dried, sand the entire frame to create a smooth, uniform surface. Pay particular attention to the joints and edges. The completed frame should be sturdy, square, and ready to receive the side panels and seat supports.

Adding the Seat, Sides, and Lid

With the frame constructed, attention shifts to adding the seat supports, side panels, and the hinged lid that provides access to the storage compartment. Each element contributes to the functionality and aesthetic of the bench.

Cut the lumber for the seat supports according to the cutting list. These supports will run horizontally across the frame, providing a surface for the seat planks to rest on. Space the seat supports evenly across the frame, ensuring that they are adequately supported by the side and front/back rails. Attach the seat supports to the frame using glue and screws.

Cut the lumber for the side panels according to the cutting list. The side panels will enclose the storage compartment and provide additional support to the frame. Attach the side panels to the frame using glue and screws. Ensure that the side panels are flush with the top of the frame, creating a smooth surface for the seat.

Cut the lumber for the seat planks according to the cutting list. The seat planks will form the seating surface of the bench. Arrange the seat planks across the seat supports, leaving small gaps between each plank to allow for water drainage. Attach the seat planks to the seat supports using screws. Ensure that the screws are countersunk to prevent them from protruding above the surface of the seat.

Construct the lid by cutting lumber to the desired size and shape. The lid should be slightly larger than the opening of the storage compartment, allowing it to overlap the edges. Attach the lid to the frame using hinges. Choose hinges that are appropriate for outdoor use and that are strong enough to support the weight of the lid. Install the hinges carefully, ensuring that the lid opens and closes smoothly.

Consider adding a latch or locking mechanism to the lid to secure the contents of the storage compartment. A simple hasp and staple can be used, or a more sophisticated locking mechanism can be installed. Choose a latch or locking mechanism that is appropriate for outdoor use and that is resistant to corrosion.

Once the seat, sides, and lid have been installed, sand the entire bench to create a smooth, uniform surface. Pay particular attention to the edges and corners. The bench is now structurally complete and ready for finishing.

Finishing Touches

The final stage involves applying a finish or sealant to protect the wood from the elements and to enhance its appearance. This step is crucial for extending the lifespan of the bench and ensuring that it remains aesthetically pleasing for years to come. The type of finish or sealant to be used will depend on the type of wood used and the desired aesthetic.

Before applying the finish, ensure that the bench is clean and dry. Remove any dust or debris with a brush or cloth. If necessary, sand the bench lightly to create a smooth surface for the finish to adhere to.

Apply a coat of wood preservative to protect the wood from decay and insect infestation. Allow the preservative to dry completely before applying the finish. Wood preservatives are typically clear and will not alter the appearance of the wood.

Apply a coat of wood sealant or stain to protect the wood from moisture and UV damage. Choose a sealant or stain that is appropriate for outdoor use and that is resistant to fading and cracking. Follow the manufacturer's instructions for application.

Allow the sealant or stain to dry completely before applying a second coat. Two coats of sealant or stain will provide better protection than one coat. Allow the second coat to dry completely before using the bench.

Consider adding decorative elements to the bench to enhance its appearance. These elements can include trim, moldings, decorative hardware, or painted designs. Use outdoor-grade materials and finishes to ensure that the decorative elements are resistant to weathering.

Once the finish has dried and any decorative elements have been added, the outdoor storage bench seat is complete. It can now be placed in its intended location and used for seating and storage.
