The project of a modular kindergarten, based on a container modularity. This project is a solution to the growing need of high quality spaces for children in Poland. Low cost construction with a fast delivery time makes it a perfect solution for public and private kindergartens. An open space layout was designed to ensure a maximum freedom in arranging the internal distribution and a way the building should function. To provide an optimal and safe environment for children to play, additional covered units were added on the building perimeter to provide shade and shelter. We have carefully chosen the materials to obtain safe and ecologic building.
