The goal of this thesis is to create a design documentation for a kindergarten. This building is situated in the city called Brtnice – more specifically in its newly established location Nová Čtvrť. The kindergarten has two floors. Walls of the first one are partly sunken under the surface level. Each floor is divided into an operating section and part for a preschool education. The building has a foundation made of plain concrete bands, built from an aerated concrete and has a flat roof. Following building project puts an emphasis on a spatial and architectonical layout, energy savings and overall safety
