First, I made a basic model. I was inspired by the tetrapod shape. This shape can be organized by the user. And you can group as many benches as you want.
This is the second development. I made the hole under the sitting, so user can keep their stuff like the bag. However, if the thickness of the sitting part it will be able to break well.
This is the third development. I made the back of a chair on the bench.
I thought of the back of a chair for relaxing. However, I thought I have to look for a comfortable degree for building the back of a chair. Then, as you look at the photo shoot, there is a small space without a backrest, which I could not solve because I was not good with programming skills.
This is the fourth development.
Usually, we could not sit on the bench when it’s raining. So, I thought of the bench where rainwater can be removed quickly, it was thought that rainwater could evaporate quickly if rainwater passed through the bench and the area covered by the rainwater was small. So I made the three-hole on the bench.
