Valentina Čanađija, mayor of Čazma, officially opened the renovated sports facility on the sports grounds in Omladinska Street, better known to residents as the "balloon". Following the completed reconstruction and energy renovation, the building has been made available again to sports clubs and citizens, offering significantly improved conditions for training, competitions and recreation.

Representatives of the Čazma City Sports Community, sports clubs, the construction contractor, technical supervision and collaborators attended the opening. The facility was blessed by Father Lauš, and the mayor used a whistle to mark the start of the first match. The first game was played by the youngest members of Čazma's sports clubs.

The reconstruction and energy renovation have given the sports facility a new look. The works included replacing the existing floor covering with a modern PVC substrate, reconstructing the wall and roof cladding using sandwich panels filled with mineral wool, and replacing the existing lighting with more energy-efficient LED lighting. The renovation places particular emphasis on improved thermal insulation, as the previous building was covered with tarpaulin.

During the execution of the works, the extremely poor condition of the support columns was identified, as they were completely rotten. Consequently, additional works not included in the initial cost estimate had to be carried out. During the summer months and September, additional measures were taken to rectify minor irregularities in the building. The works were carried out from 16 February to 29 May 2026.

The City of Čazma's project for the reconstruction and energy renovation of the sports facility began in 2025 with an application to the Ministry of Tourism and Sport's public call for co-financing the construction and reconstruction of sports facilities for 2026. After signing the contract with the Ministry, a public procurement procedure was conducted. VINTER GRADNJA d.o.o. was selected as the construction contractor, while HM Projekti d.o.o. provided technical supervision.

The total value of the works carried out is €700,894.59 including VAT. The Ministry of Tourism and Sport co-financed the project with €400,000.00, while the remaining €300,894.59 was secured from the budget of the City of Čazma. The renovated "balloon" is intended for sports clubs and citizens who engage in sports recreationally, and it allows for volleyball, futsal, badminton, tennis and handball.
