135 is a bench family sitting together "Solo," "Trio", and "Quintet". This project is based on different seat heights allowing users to communicate better. These modules create an evolution. These three parts have the same characteristics and show the idea of a mutation, an extension based on the number of people they can accommodate. It also allows to create ventilated areas for the flow of water and dirt, but also on the bench or in the vicinity, the user has the opportunity to see what is happening around him or to get back in the areas where the sheet is not perforated .
