The addition of an eastern wing with a distinctive butterfly roof expanded its scope. In recent years, the City Municipality of Ljubljana tasked the company OD-DO architecture and Navor with renovating and expanding the structure as part of a broader energy efficiency effort for public buildings. Collaborating closely with the client and future users, the team recognized the need for more than just new classrooms. They added central gathering spaces, a well-arranged entrance area, three modern classrooms with ample natural light, a distribution kitchen, and a locker room.

The project prioritized sustainability, opting for wood construction to seamlessly integrate new elements with the existing concrete structure. Separate entrances for various age groups were established under spacious canopies and integrated benches. Corridors hosted shared playrooms and locker spaces, transforming the former locker room into the heart of the kindergarten. Reconstruction of the ground floor perimeter walls introduced more natural light, creating open and inviting spaces. Additional land on the northern side of the kindergarten was acquired for expanded outdoor areas and parking, encircling the kindergarten with a green belt, providing an enriching outdoor environment for children.

This holistic approach balanced modernization with respect for the original design, resulting in a rejuvenated and functional kindergarten.
