The main problem for which this project was initiated is insufficiently adapted and attractive public infrastructure of the Target Area of the Kaunas city of Aleksoto to promote investment, social and economic development. The solution is the modernisation of abandoned and unused infrastructure with potential, in order to create favourable conditions for investment and economic development. During the project, it is planned to reconstruct the former aviation plant hangar, European av. 27, in Kaunas city, by adapting the structure to production and production administration and to remediate the area around the building. After reconstruction, the hangar with its modern infrastructure will be ready to set up innovative companies. The reconstructed hangar will also complement the innovation ecosystem in Kaunas by becoming a bridge between the development of large production capacity and the launch of technology innovations in the market.
