DIY: Build Your Own Outdoor Bench!

By: albertaarb - June 10, 2014

If you're looking for a functional but stylish DIY outdoor bench we have a step-by-step guide on how to construct one. We normally deal with the removal of trees and shrubs, along with care and pruning, however this is a guide for putting things together. This outdoor bench will make a great addition to your home: it will provide extra seating, storage and is easy to put together.

This design is not completely waterproof, but you can apply sealant if you'd like.


You will need the following supplies before you can begin:

• Two 1630 x 340 x 12mm pieces of exterior plywood for the sides.

• Two 500 x 340 x 12mm pieces of exterior plywood for the ends.

• One 1630 x 524 x 12 mm piece of plywood for the bottom.

• One 1635 x 530 x 12mm piece of plywood for the top.

• Six 31 x 31 x 340mm blocks.

This is for the shell of the outdoor storage bench.  For the outside of the bench you will need:

• Six 19 x 19 x 1668mm pieces of wood for the sides.

• Six 19 x 19 x 524mm pieces of wood for the ends.

• Ten 19 x 19 x 90mm pieces of wood for the feet.

• Two 19 x 19 x 530mm for the end of the lid of the bench, so it doesn't fall off.

• Two 19 x 19 x 1673mm pieces of wood for the side of your lid, so it doesn't fall off.

• Six 19 x 19 x 1800 for the top of the bench.

You also need wood glue, varnish to stain it, sealant if you want to waterproof it (some varnishes come with a sealant), a drill and 30mm screws.  The screws should be rust resistant since the bench will be exposed to rain and snow.

Building Your Bench

Now comes the fun part: putting your bench together.  We will describe this in the most basic terms so you can put it together quickly and easily.  Take your two pieces of side plywood and attach three blocks to it: one on each end and one in the middle to strengthen it.  Drill a hole at the top, middle and bottom of both pieces of plywood along each side: these will be used later to attach your wood.  Now glue the blocks to the plywood, so it makes a box shape. 

Repeat this process on the ends, then attach the bottom piece of plywood with glue to the blocks and drill holes at the four edges to screw the feet in, later on.

To attach your wood, take your six side pieces (three for each side) and drill two holes in each piece, one at each end to line up with he holes in the plywood.  Screw the wood on, then repeat on the sides and bottom. Finally, attach the wood for your lid to the plywood for your lid, then glue the two side lid pieces and two end lid pieces.  Screw them together and place on top of the bench when your done.  Flip the bench upside down and screw in the feet and voila: you did it!

Bench Finishes 

Now all that is left is for you to varnish.  After staining it wait at least two days for it to dry, a week is ideal.  Place the lid on top and if you want you can add cushions.  Congratulations, your DIY outdoor bench is now ready to use- have a seat and enjoy it!
