In the summer or on a lovely rain-washed evening, there's nothing better than a tree bench to relax on, with a book and a cup of coffee. Communing with nature from the comfort of your own garden under the canopy of your favorite tree can be an idyllic experience. Here’s how you can build your own garden tree bench.

Step 1 - Cut the Lumber

Once you have purchased the lumber, cut it in the following measurements.

10 pieces for the seat – Length 23 inches by Depth 10 inches by Width 2 inches

10 pieces for the legs – Length 16 inches by Depth 6 inches by Width 2 inches

5 pieces for leg and seat support – Length 28 inches by Depth 2 inches by Width 6 inches

You will need to cut the pieces for the seat at a 30-degree angle. Initially, you may cut 4 pieces and lay them flat to check if the cuts are precise. In case you find a variance, you can make corrections by adjusting the angles in the next pieces you cut. Once all the 10 sections are cut, lay them in a circular fashion, one connected to the next.

Step 2 - Attach the Legs

Nail each leg to the end of the support pieces using two nails. To give the legs more stability, connect the brackets to the sides of the legs along with the undersides of the support pieces, using 1½ inch screws. You may choose to make the legs a little longer, so they can be sunk into the ground. You will, however, need to ensure that you maintain a uniform level in that case.

Step 3 - Connect the First Seat Section

Place one support piece in the center of one seat piece. Leave equal room at both ends. Using a C clamp, fix the support piece and turn over the seat. You will see that the seat now rests on the support. Mark a spot 2 inches from each end of the seat section as this is where you will drill holes through the top of the seat and the support section simultaneously. To hide the head of the bolt, use the 5/8 inch bit, and countersink a hole to about ½ inch depth.

After holes are drilled for one seat, place the 3-inch bolts into the holes down through the support section. Nuts should be tightened slightly. Remove the C clamp at this stage.

Step 4 - Connect the Remaining Seat Sections

Now move on to the next seat piece. Hold the second seat against the first in such a way that it rests on top of the end portion of the support piece.

Like before, using a clamp, drill two holes through the seat and the support piece. Place the bolt through both. Tighten slightly. Once you have done the same procedure with the seat piece on the left of the support piece, you should have three seats held together with one support. Make sure that you leave the ends of the right and left seats unbolted, so you can continue to attach the support pieces until nine total seat sections are connected.

Step 5 - Finish Up

Assemble the complete bench around the tree before you bolt the final piece in place. Sandpaper any rough edges and then paint or stain your new tree bench.
