In the south-western part of Katowice Airport, by aircraft apron no. 4, a hangar for General Aviation aircraft was built. The building covers 5 452 sq m, is 41 metres deep, 11 metres high and 133 metres wide. When it comes to width, it is the biggest hangar object currently available at Katowice Airport.

The building consists of three independent segments; each allows to store not only business aircraft (A-C code), but also helicopters. PROMUS sp. z o.o. was the main contractor responsible for the investment. The commissioning of the facility was combined with the presentation of a Gulfstream Aerospace aircraft; the company is one of the largest manufacturers of business jets in the world.
