The terminal building is reduced down to the basic forms of the longitudinal wing with triangular cross-section and the rectangular hall. The structural "trees" supporting the roof are the inimitable characteristic of the airport building. The skeleton corresponds to the structure of the compound umbel. Force flowing from the roof loads is transmitted down into the "twigs" via a narrow grid of supporting members (4 to 5 m span), groups of four branches being supported by a further thicker "branch" each. Twelve tube section "branches" combine to form one of the "tree trunks" which tie into the base.
The skylights directly above these supports are equipped with heliostats. Movable mirrors follow the sun and deflect sun rays onto the steel treetops down onto the floor tiles around their bases. Reflectors arranged within glass tiles throw the light back onto the underside of the tree canopy.The ventilating system is a free-standing installation with pipelines and jet nozzles. Thus the ventilation technology becomes a design tool within the new hall environment.
Corresponding to the linear arrangements of aircraft positions, the waiting halls and connecting passages are aligned in a long element which serves as a noise barrier towards landside. The raking façade surfaces bind the building mass into the typography of its environment. The huge aircraft hangar opens up on all sides as a weather-protected open space and dominates the complex, forming a large-scale "airport marker".
On the apron side both building forms overlap and interpenetrate. The longitudinal building’s ridge dissolves in staggered levels into the hall, curving out in a semicircle in the middle. The façade of the plinth is clad in natural stone. The windows are recessed and set vertically in natural stone in the slanting façade surface – the monolithic plinth thereby acquires a sculptured quality. The light weight steel structure of the large concourse hall rises above. The glazed south front of the great hall is shielded from the sun by motordriven shading devices. The analogy to aircraft wings and landing flaps is intentional.
