The vision of a new community building was conceived years ago at the parish of Szent István Telep, Budakalász. Several architectural plans were made for this purpose. The Roman Catholic Archdiocese of Esztergom–Budapest decided on starting the expansion in 2018, initiating a public procurement process for its construction based on the plans of Zoltán Galina and László Földes, relying on state grant resources. The construction works started in January 2019, and we were responsible for fulfilling tasks related to Technical supervision and technical project management. The project was successfully closed in the spring of 2020, to every stakeholder’s satisfaction.
