Sheltered sports facilities are a cost-effective alternative to capital structures. Unlike stadiums and fixed indoor arenas and complexes, they have a number of significant advantages: extremely short construction time; low maintenance and repair costs; mobility. Technically, a sports hall hangar is a much simpler solution than any capital structure. Its construction does not require significant excavation, deep foundations or expensive walling materials. This reduces the cost by more than an order of magnitude and shortens the construction time.
