Step 1:

After I took the right measurements and figured the number of pieces I need, I started cutting them.

Step 2:

I used some scrap pieces of wood, which I had left over, from an old construction and then I cut the edges on every side of those beams.

Step 3:

After that, I filled every hole with glue and some dowels.

Step 4:

And then I sanded them very well on every side.

Step 5:

Now, it’s time to assemble all these pieces!

Step 6:

Firstly, I nailed and screwed these two pieces together.

Step 7:

Then, I took the longer pieces, marked the center, drilled the holes, placed the screws and put them together.

Step 8:

After some sanding, I rounded all the edges on every piece.

Step 9:

And then, sanded them again for a smoother feeling.

Step 10:

After, I finished with the bottom pieces, I started to cut all the slats I needed for the top surface.

Step 11:

I rounded also these pieces, but this time only their two edges.

Step 12:

And then I sanded every piece very well on every side.

Step 13:

Now, it’s time to paint all these pieces!

Step 14:

I used water based impregnation varnish of walnut color and there we go!

Step 15:

Let’s assemble these pieces together and see how it looks!

Step 16:

After I measured the spaces I had to leave, I placed down the two edge pieces and then all the others going in between.

Step 17:

I used a spacer for every gap between the beams to be the same.

Step 18:

I installed some felt pads at the bottom side, to avoid any damage on the wood.

Step 19:

Also, I placed screws at the edges and in the middle to be even steadier. Black screws actually for a more beautiful appearance.

Step 20:

...and the bench is finally ready!

Thanks for reading! I hope you liked it!

    Great looking bench.

    I'd like a few measurements:

    1. dimensions of seat slats. Did you use 5/8" lumber

    2. distance between each support wood slat

    What do you think of screwing in the slats from the bottom so there the top shows no screws and eliminates possible water seeping in the top screw holes?

    Thank you very much, Mike and I’m so happy that you liked it!

    Take a look at the 1st step, at the 1st image, where I’m showing the dimensions of the slats (width, length, thickness) and the distance between them! Here we use the metric system, so all the measurements are in mm, sorry!

    I didn’t screw the slats from the bottom side to the top surface because they were too thin and some of them were crooked, so I couldn’t do that!

    Take care!

    You didn't Attach the bench seat to the wall, did you? Does it move or is the weight alone keeping it in place? Would love to know. Thank you!

    Yeap, I attached it to the concrete with two screws, one on each end,
    in order not to move when someone sits at the edge of the bench, but
    when it’s not in use, I remove the screws and everything is good!
