How to Build an Outdoor Bench How to Build an Outdoor Bench

What You'll Need
12 pieces of 2 X 4 X 18 inch spruce
Wood glue
Drill
Screwdriver
2 1/2-inch deck screws
4 pieces of 2 x 4 x 48 inch spruce
Carpenter's square
6 pieces of 2 x 4 x 48 inch spruce

An outdoor bench seat on a patio or under a tree can be a beautiful addition to a home. If you can't seem to find a bench in stores that you like, you can always build your own outdoor bench seat. It is easiest to build this type of bench out of wood. All you need are a few power tools and some time.  

Step 1 - Lay Out Material

Put twelve of the 18 inch 2x4s on a worktable, laying two horizontally and parallel to each other about 9 inches apart. Add glue to the ends of the two pieces of wood.

Place two pieces perpendicular to the wood that has the glue on it so that the 3 1/2 inch sides touch each other. Line the end of the top 2x4s with the perpendicular edge of the first 2x4s. Attach the four 2x4s to each other using deck screws. Keep doing this for all the 2x4s.

Step 2 - Cross Members

Put the 48 inch 2x4s on a worktable, standing one of the support systems you created in the first step upside down to create a cross member on the table, with two legs sticking up. Add glue to one end of the 48 inch 2x4. Line it up with the cross member 2x4, securing it with deck screws. Do this again for the other end of the 48 inch 2x4.  

Add glue to the other 48 inch 2x4, lining it up with the other cross member on the support system. Attach it to the support system with deck screws. Repeat these two steps with the last 48 inch 2x4s.  

Measure one end and make a mark at 23 1/4 inches. Do the same thing to the other side of the bench, measuring from the same end. This will allow you to figure out where the middle support system is going to go. Before applying the support system and attaching it with decks screws, add glue to the area.

Step 3 - Turn the Table

Turn the table over so that it's standing on the legs. Put glue on the top perimeter of the bench and across the middle support. Place the last six 2x4s on top of the bench, securing them with deck screws.  

Tips

  • To be safe, consider counter sinking the screw holes on the top of the bench.
  • Remove extra glue using a damp cloth.
  • This project is best completed with spruce, although you can use western cedar 1x4s around the perimeter of the bench as another option.  
  • Where gloves at all times to protect yourself from splinters. If you plan on painting or staining the bench, make sure you do it in a well-ventilated area.
