How to Build a Patio Bench

Patio benches can help add seating, and thus practicality and enjoyment to any outdoor living space. Choosing to build your bench with lumber can add portability and durability to your finished product. Construction is not as complex a task as you might think. Clear off an afternoon and get started.

Seating at family gatherings and parties can be challenging. Many do-it-yourselfers can resolve these issues with some lumber, basic tools and a free afternoon. Building your bench using lumber makes it portable and durable at the same time.

1. Select the wood type that you would like to use. Many people use cedar or pine. Make sure your wood is treated to ensure maximum durability. You will need two 2-by-4-by-8 boards, one 2-by-10-by-8 board, and one 4-by-4-by-8 post to get started. Ensure that you have some 3-inch wood or deck screws as well.


2. Cut two of the 2-by-4s into 36-inch pieces. Set the cut pieces aside and lay them down parallel to each other.


3. Cut two 15-inch pieces also from the 2-by-4s.  Form a rectangular frame using the four cut pieces.


4. Drill a couple of starter holes. The holes should be positioned on the outside ends of the long cut pieces and through the ends of the shorter cut pieces. Insert the deck screws into the pilot holes and complete the construction the seat frame.


5. Using the 4-by-4 post, cut four pieces measuring 18 inches each. These will be the legs for your bench. 


6. Using the 2-by-4s, cut two pieces, each measuring 36 inches long. Cut another 36-inch piece from the 2-by-10. These pieces will form the bench top.


7. Select a stain type and color for your bench. Stain the constructed frame as well as the remaining cut pieces. Applying the stain prior to completed construction will ensure all sides of the pieces receive stain. Allow the stain to dry before continuing.


8. Complete construction of the bench by placing the ends of the 4-by-4 legs in the inside corners of the bench frame. Drill a couple of starter holes on the outside of each corner and also in the leg posts. Drill in the deck screws to complete the bench.  Four screws should be used in each leg to ensure stability.


9. Turn the bench over so that it is standing on its newly constructed legs. Take one of the pre-cut 2-by-4s and place it on the seat frame. Be certain to properly line up the board onto the frame and drill starter holes through the board and frame. Insert the screws.


10. Position the other cut 2-by-4 on the frame lining it up with the back and side of the bench frame. Drill starter holes through the board and frame. Insert the screws.


11. Position the cut 2-by-10 piece between the 2-by-4s already installed on the patio bench seat. Remember to drill starter holes through the 2-by-10 and also into the bench frame. Insert the screws.


12. Enjoy your completed bench!
