How to Make Your Own Garden Bench

By Katherine Kally ; Updated September 21, 2017

You can easily make your own garden bench with the right tools and materials and minimum building skills. Make your garden bench from wood that’s been treated to withstand the elements or from woods like cedar or teak, which is naturally insect and mildew resistant. Making this 36-inch-by-18-inch garden bench is a simple craft project that you can adjust to fit the space in your garden. You can find the materials necessary to make your own garden bench at your local home improvement store.

Lay the three 36-inch-long boards side by side to begin making the seat for your garden bench. Make sure that the ends are flush. Measure to make sure the sides are 1/4 inch apart.

Support your bench seat with the three 17-inch-long teak boards. Center one of these boards across all three seat boards. Center the remaining two 17-inch-long boards between the outside edges of the bench seat and the center support. Your support boards should be placed perpendicular to the garden bench seat boards.

Attach the support boards to the bench seat with 3-inch decking screws. Place the screws every 2 inches along the length of each support board.

Stand one 18-inch-long teak board vertically in one corner of your bench seat. The 18-inch long teak boards are the legs for your garden bench. Place an L bracket against the vertical leg board and the bench seat. Attach the L bracket to the leg and the seat with 1-inch decking screws. Repeat this process to attach the remaining three legs of your garden bench.

Coat the entire garden bench, including underneath the seat and all around the legs, with wood sealer to protect the wood against moisture damage.
