Awesome design. was the Polystyrene board 20mm thick used for the sides? Can that be purchased at Home Depot? In step 4 what is that middle picture of? Did you spray anything on the sides and bottom to make removal easier? Do you mind if I make something similar? Thanks
Actually, you could make a stepping stone or two with the leftover cement as well.
Beautiful piece. Very good instructions. Ty. <br>
Cheers mate, Thanks :)
A wonderful project and a very well thought through design with a clear step by step design for others to use. <br/><br/>Possibly I would reexamine the pedestals/feet, either enlarge the diameter of them or amend their shape to that of a more rectangular shape.
Hey thank you for youre good words,<br>You are right and I am about to make a new skech for the legs.
Dissolving styrofoam is good fun, but you get a gummy liquid. When sides are straight it should be easy to chip it out with a screwdriver.
I did so utill the middle but it was stuck down deep so i had to dissolve it
My house is built in a way, that there are alot of sharp edges between the outer walls, so i was looking for a decorative way to make it look more smooth and curly by making the bench curly and placing it between the walls
I too studied industrial design. What was the problem you solved by creating this curved bench? Where should it be placed?

Hi Adam,nice project, <br>i wonder wether the inner structure is strong enough? <br>You did not use any irons in the concrete, so there is a chance the outer ends might brake of when someone sits on it? <br> <br>Also the feet construction with them 2 pipes does not really fit the design, you have this wave shaped bench with open slots following the shape, and than you just use 2 standard pipes, <br>if you're an ID student, than i would improove the feet and come up with a design that complements the top. <br> <br>Other than that, concrete is in my opinion underrated as material, so hope to see more of these projects from you .
hey BG thanks for youre reply<br>well i did put irons on the outer shell of the bench as you can see in<br>Step 5: Adding the Frame and Styrofoam Blocks<br><br>I totaly agree with you, the feet construction was wrong, and its too thin i missed it and i think i'll do it in a different form, i'll might be using bucket full of concrete to make a thick and low feet
Normally you create the bevel (or fillet) by carefully squirting silicone along the mold corners and following with tool or finger.
Thanks for the tip danzo!<br>The reason i did not use this methood is because i wanted to show up and expose the stone texture withing the concrete.
Terrific project and flawless step by step instructions. I'm sharing. Thank you!
Sharon, thank you for youre comment! :)
How did you attach the styrofoam inside the frame?
Hey, I attached the styrofoam with silicone glue same as iv attached the wooden supporting
