UP! BERLIN
TRANSFORMATION KAUFHOF AM OSTBAHNHOF
Jasper Architects has transformed Berlin's old shopping mall into a new mixed-use office building covered by fully glazed façade with cut-out form. Called UP Berlin!, the 55,000-square-metre office building is currently under construction in Berlin's Friedrichshain district
THE CHALLENGE WAS TO CREATE SPACES CAPABLE OF HOUSING WORKING SPACES INTO THE EXISTING MASSIVE BUILDING BLOCK OF A SIZE OF 80 X 80 METERS
THE BIGGEST CHALLENGE WAS TO BRING NATURAL LIGHTING INTO THE BUILDING. A FIRST CONCEPTUAL ANALYSIS WAS TO FIND A GEOMETRY THAT WOULD MAKE A PERFORATION POSSIBLE IN ORDER TO FIND AN EQUILIBRIUM OF THE LEAST LOSS OF REAL ESTATE AND THE MAXIMUM OF NATURALLY LITTEN SPACE, RESULTING IN A TRIANGULAR CUT-OUT.
THE IDEA THEN WAS TO USE THE CUT OUT SPACE ALSO TO LOOSEN UP THE MONOLITIC GEOMETRY OF THE EXISTING BUILDING, BY BRINGING THE CUT-OUT VOLUMES TO THE FOUR FACADES.
THE LOST REAL ESTATE OF THE CUT-OUT VOLUMES IS ADDED ON THE TOP OF THE EXISTING STRUCTURE FOR COMPENSATION OF THE LOST AREA.
THE RESULT IS AN OPEN BUILDING ON ALL FOUR SIDES REDEFINING THE BUILDING 'S URBAN PRESENCE ENTIRELY.
BY SHIFTING THE BUILDING'S EDGES, THE POSSIBLE VIEWS AND PERSPECTIVES FROM THE BUILDING VARY.
THE SHIFTED EDGES ARE THEN TERRACED TO GENERATE USABLE EXTERIOR SPACES OF ALL VARIETIES AND ON EVERY FLOOR AND EVERY SIDE OF THE BUILDING.
THE TERRACED VOLUMES GOT THEN OPTIMIZED STRUCTURALLY, AS WELL AS FOR LIGHTING AND INTERIOR LAYOUT FUNCTIONNALITY.

Transforming East Berlin's Old Shopping Mall
In 2016 JASPER ARCHITECTS won the competition organized by Signa, Austria's largest privately owned real estate company, for an over-all redesign of the Building of the former
"Centrum Warenhaus" of the GDR, built in 1979. The competition task was to present a
concept to turn this massive square building block of 80m length and 80m width into
usable office space, generating future work places for the digital era.
Biggest challenge
The biggest challenge was to bring natural lighting into the building. The logical consequence of shaping out an inner courtyard was twisted around: The presented idea was to cut triangular haped prisms on each side of the square building, in order to flood the interior with natural light and by this loosen up the massive monolithic geometry of the existing building. These created voids redefine the building's urban presence entirely, opening the volume up on all four sides. The voids, as well a strategic terracing and twisting of the floors, optimize views to central Berlin. All floors have access to outdoor communal spaces for working, entertaining and relaxing.
Redesign
For the redesign, the existing Building is stripped down to its structural concrete columns and floorplates. Then wrapped in high-quality glass, what was once an interior-focused shopping center has been reimagined as an outwardly-focused center. To compensate for the cut-out real estate, two floors are added on the top. A big roof top terrace creates an amazing view on Berlin.
