The task of this project is to design a complex, the main part of which consists of a daycare centre for children aged between 2 and 6, a place for consultation and assistance to parents as well as a centre for consultation with specialists.The main reason to choose this topic is the fact that in recent years in Bulgaria and in big cties in particular the crisis with kindergartens conditions and free spaces has deepened due to insufficient state funding. A great advantage of the capital city of Sofia is its proximity to the Vitosha mountain. It is this natural phenomenon that presents the opportunity for the children campus to be situated at a place with unique natural environment at only 20-30 minutes from downtown. The project focuses on the relationship and interaction of children with the nature and parents. Due to this reason many areas are intended for kids that they will rediscover every day: winter gardens, children slide, green roofs fitting into the natural terrain, various sports premises, water activities, discussions, workshops, music and theater.Basic principles in the design of the building are maximum fit to the natural terrain, the use of natural materials (in building construction as well as in the facades and interiors), efficient use of energy and water, visual and physical presence of nature in the building.
