How to Build a Backless Wooden Bench


A bench is a great way to provide seating in an outdoor area. Simple benches can add decor to your garden or lawn and can tie a landscaping project together. If you are planning on adding a backless bench to your yard, consider building one yourself. This way, you'll save on the cost of a bench, and it will be exactly what you want.

Things You'll Need

  • 8 1-by-4s, 47 1/2 inches long
  • 7 1-by-4s, 14 1/2 inches long
  • 4 4-by-4s, 17 inches high
  • Measuring tape
  • Pencil
  • 1-inch wood screws
  • Drill with screwdriver bit
  • Place two of the pieces of 4-by-4 side by side on a flat surface. Measure 4 1/2 inches from one end, using a measuring tape, and make a mark with a pencil. Place a piece of the 14 1/2 pieces along these marks so the edges of the 4-by-4 pieces are even with the ends of the 1-by-4. Screw these pieces together by drilling screws through the 1-by-4 into each piece of 4-by-4. Repeat this for the other two pieces of 4-by-4 and another piece of 1-by-4. These are the sides of the bench.

  • Turn the sides of the bench on their ends so the pieces of 1-by-4 you just attached are standing straight up. Place a piece of 47 1/2-inch 1-by-4 across the 4-by-4 at the same height as the 14 1/2-inch 1-by-4. Screw this piece to the 1-by-4 and 4-by-4 by driving in screws through the sides of the longer 1-by-4 into the ends of the shorter 1-by-4 and the sides of the 4-by-4. Repeat this step for the other side of the bench. You should now have a rectangular frame with four legs.

  • Measure 8 1/4 inches from the top of the 1-by-4 frame and make marks on the 4-by-4 pieces. Create another rectangular frame with two pieces of the 14 1/2-inch 1-by-4 and two pieces of the 47 1/2-inch 1-by-4. Attach the frame to the legs of the bench by driving screws through the 1-by-4 and into the 4-by-4. This frame should mirror the lower frame and stick over the top of the legs by 3/4 inch.

  • Place a piece of 14 1/2 inch 1-by-4 inside the bench frame, next to the pieces of 4-by-4 and even with their tops. Screw that piece into place by driving screws through the 1-by-4 frame and into the edges of these support beams. Mirror this piece on the other side of the bench by placing another piece of 14 1/2-inch 1-by-4 next to the top of the legs on the other side and screwing it into place.

  • Measure 18 inches from the pieces of 1-by-4 you just placed toward the center and make a mark. Place pieces of 14 1/2-inch 1-by-4 inside the frame at this mark so they are even with the tops of the legs. Screw them into the frame by driving screws through the frame and into the ends of the support beams.

  • Place the four 47 1/2-inch 1-by-4 boards on top of the frame. They should run the entire length of the bench top and be spaced 1/4 inch apart. Screw these to the cross beams by driving screws through the top of the bench seat into the edges of the cross beams.
