The topic of this diploma thesis is design processing of a new sacral building in Brno-Líšeň district. It is a plot in the middle of a panel building between the health centre building and the building of the Salesian Youth Center, so-called Salesko. The Salesian community, which will use the building the most, has been waiting for the realization of this building for many years. The key theme is the creation of spaces enabling people to meet for worship, celebrations and social events. The design is processed by two interconnected operations - the building of the Church of the Descent of the Holy Spirit and the building of clergy house. The basic composition consists of three cubic masses - the entrance, the main liturgical space and the clergy house. The bell tower is the height dominant feature which indicates the sacral function of the building. The project consists a set of buildings with two above-ground floors and a basement in the entrance part of the church. This project also mentions the solution of open spaces around the plot and their conversion into quality public areas, marginally. The sacral space is to become a place that welcomes and takes in its visitors and gives them the feeling of safety. Inside this building, people will find peace, support and undestarstanding, so they may leave with the feeling of being a better person.
