Examining how the body inclination can change while people are seated in public spaces for a long time, how the body moves through the time. After creating a typology of basic body inclinations and combining all the lines, an interesting design aroused. This special organic form reminds us of the continuous flow and movement of the water; the creation of small wave's curves. That's how the project is named "fluid". The first goal is to create and design according to human needs and bodies. This project is a combination of landscape design and human-centered design. This optics could impact new architects and landscape designers to design according to human bodies.The bench was made via a robotic 3D printer for big scale items.Next goal is to keep using concrete as a material for small construction and sustaible.We can replace all those tones of concrete used for buildings with more eco friendly materials and use all stock material of concrete in small things that can be put outside.
