Kusus + Kusus architekten’s BBI-Info Tower at the Capital Airport in Berlin is designed to be a recognizable element for the airport that will “serve the whole region and far beyond the boundaries of the construction site beyond.” Rising 31 meters, the tower is a welcoming sight for visitors approaching by land or passengers on plane. Programmatically, the building is a observation tower that provides views of the “growing” new airport complex which is currently being developed. By ascending to the top, the visitor is then roughly at the level of the surrounding construction cranes and gains new insight into the construction activities.
More images and more about the tower after the break.
Inside, a massive reinforced concrete elevator core carries the weight of the entire structure, allowing the exterior envelope to portray a feeling of delicacy and lightness. Steel spiral stairs cantilever off the core with intermediate landings that provide areas of rest during ascent and descent, as well as views of the site through the semi-transparent envelope. Upon reaching the top, there are two observation decks, an encased platform and an open deck.
On the exterior, the tower is a series of isosceles triangles that, on each level, are rotated six degrees counter-clockwise. This results in an unusual and striking form that creates different perspectives from each angled viewed. The idea of dynamic twisting can be rationalized as an architectural interpretation of wind or motion, as associated with the airport.
The exterior, a white ETFE membrane, allows a certain degree of visual transparency during the day and creates a light tower at night, as different colors burst through the translucent skin. The tower’s spatial impression is the effect of the membrane stretched between the triangular steel frame.
As a parti, the tower is the simple relationship between a round core and spiral stair rotated within the triangular frame of the facade.

was there a butterfly out of this pupa?
Elegant form. Beautifully executed.
Givus us drawerings!
It is like a beautiful hi-tech version of the tower at Johnson Wax Co by F.L.Wright. Looks really well detailed on top of being an interesting overall shape. The coloured light displays are suprisingly striking. Agree that it would be great to see more of this project, including the base building.
i’m an architecture student with my final tomorrow. long story short, they literally stole my idea! ha ha. it appears the wheel has already been invented, again…
you’re just product of your times and education, noob
what about the overheating problems caused by the use of a transperant material for the exterior layer ??
has it been put in consideration ?
Isn’t this the first shape everyone does when they learn Rhino? i.e. lofting exercises.
Yeah, this one has Rhino written all over it… but still, it is a beautiful design!
Beautiful fusion of form and technology. Looks like everything has been considered.
