How To Build A Simple Patio Deck Bench Out Of Wood Step By Step

If you have a patio and want to build a nice but cheap wooden bench, then see our simple tutorial below. This DIY wooden patio bench will cost you around $40 dollars in wood and $6 dollars for the box of wood screws to put it together. We did not stain our bench as we like the look of it the way it is. If you plan to use wood stain on your wood bench then add in a few more dollars. This woodworking project took us nearly 3 hours to fully complete. From cutting the wood pieces to attaching the wood pieces together. So if you have $40 bucks and want a fun and simple DIY wood project, see below for our step by step build through pictures.

The first thing we did was to attach the top sitting frame assembly together.
The 5 – 2x4x11″ and the 2 – 2x4x44″ pieces.

Next, we screwed the 4×4 legs into the top sitting assembly structure.
Secure these with 4 of the wood screws on each leg.
Using some wood glue here is also helpful to secure the pieces together.

The next step is to get the 4 – 2x4x48″ pieces of wood and attach them to the top of the bench.
This will be where people will be sitting so make sure the wood is free of splinters and rough areas.

  1. Do you also have the step by step plans without pictures like a blueprint for the novice wood worker? This is the bench I want to make.

  2. Your instructions are easy to follow. If I wanted to shorten the length and make another bench connected to this one to make into a 2 seat corner bench, how would I do that?

  3. Thank you for this posting. I’ve looked at so many bench ideas today and was about to log off. For some reason I clicked on your post….and am I glad. Your instructions are simple…to the point…precise. And the finished bench is just exactly what I wanted to construct for myself. I’ve printed your posting and will go to Home Depot today.

  4. Thanks so much for the instructions for making this awesome bench!!! My wife and friends are amazed at how beautiful and solid it is. I used douglas fir wood and stained using “mission oak satin” stain/poly mix. I have been requested to build several more, which I will be selling for a small profit.

    Elle,
    Yes it would be a good idea. If you are using a thicker piece of wood for the bench seating area it may not be necessary, but to be sure, a third support is a good idea.

  6. If I were to make this a 6 foot bench, would there need to be additional support in the center? Thank you. This is great.

    Hi Aaron,
    We would recommend attaching the bench to the side railing of your deck. Attaching it to your deck from the bottom may not stay secure over time. If you are unable to attach the bench to the side railing, we suggest using large anchor screws with washers and screwing them up through the bottom of the deck and into the legs.

  8. What would i need to do if i want to attach this to my deck? what are some ways to secure the bottom legs to my deck??

  9. Amazing modern DIY bench. Perfect for my back yard basketball area. I’m going to build 2 of these. Thank you so much for posting. Awesome tutorial and photos.
