New baby

Second stage

After a lot of explorations and wanderings, I decided on this form. Truly speaking, I chanced upon it while fiddling with paper. I love working with paper and this one is made by simple folding it on two curved lines. The initial model looked quite different. After series of refinement and putting ergonomics in it, it looked like this. This form will work well in ferrocement, as it uses a shell sort of a structure and is based on arches. 

While translating it from paper to ferrocement, we had to make some changes but the essential remained the same.
