The wind tunnel building is a reinforced-concrete structure with walls and ceilings of various thickness. Its almost cubic shape measures 33 m x 22 m in base and 38 m in height (11 m above ground level). 

The structure consists of an internal solid in a shape of a cylindrical tube, formed by a square with the side length of 7.5 m and contains the core technology of the vertical wind tunnel. The rooms (3 - 4.5 m wide) including: the reception, office and hotel rooms, conference facilities, bathrooms and dressing rooms are spirally arranged around it. They are accessed from the entrance hall by an inclined corridor, which ascends gradually until it reaches the glass cylinder - the key feature of the building. Inside – the powerful units generate wind of 300 km/h directed upwards, which allows people to be lifted up to more than a dozen metres. This movement along with the associations of 'floating' kites or plastic supermarket bags – the latter perhaps invoking less friendly associations – were the key inspiration in designing the external form of the building.
