She designed secondary schools and kindergartens as well as other public buildings in Šiauliai. The Wedding Palace, associated with the ideology of the Soviet’s atheism, was built in 1975 according to her design with co-author I. Laurus. The architect focused on formative buildings, as well as gates and fences, designed to shape and enhance the cityscape. The exterior facades and interiors of cinemas and numerous pharmacies were designed according to her plans. The architect also devoted herself to the design of open spaces and cultural places in Šiauliai. Parks, squares and large areas such as industrial zones or cemeteries were shaped by her planning department. Nistelienė also took sacred architecture into account in Šiauliai and other cities in the country. As was common in the Soviet period, these were typical projects found in every city. The architect lacked freedom and less creativity during the period. The restrictions of the time did not allow her to realise her original ideas and concepts. For example, when designing the cemetery, she wanted to decorate the gates with musical effects in an original way. When the gates were opened, bells would ring out simultaneously, but this idea was forbidden by Soviet government officials.
