Burda Car Park, Offenburg
Upon completion of the Burda Media Park and concentration
of several locations from Offenburg and Baden-Baden the
demand of the publishing house for parking space increased.
In direct surrounding of the new building different
possibilities were examined on the working site and adjoining
properties. Quite expeditiously, the undeveloped area near the
entrance of Offenburg between Hauptstraße and the high-rise,
which is currently under refurbishment by Ingenhoven
Overdiek Architekten as well, turned out to be a convenient
place. There, in a prominent position at the entrance of the
city, a light and subtle solution has been found, fitting the
project full-scale into the landscape.
The parking block is circular with a diameter of 60 m. In the
middle zone the entrance ramps as well as pedestrian
development are located. On five levels 474 parking spaces
are available. The access to the parking garage is on the
lowest level of the site. The vertical development is arranged
for vehicles in such a way that through two spiral ramps,
crossing each other, ascending and descending is possible
independently of each other, overcoming full floor height with
a 180° rotation.
Apart from the exceptional façade design the compact
construction method of the naturally ventilated parking block
is a distinctive feature. Through inner ramps and the
staircase, all vertical developments are integrated into the
overall. The static system consists of a continuous radial
exposed concrete core with the inserted opening ramps. The
core also serves the stiffening of the building. The different
parking decks are made in system construction from
1
prefabricated steel columns and beams, which are arranged
radially in an angle of 11,25° around the concrete core. The
floor slabs are fabricated as built-up construction of
prefabricated elements of reinforced concrete. Basing on
system construction elements the building could be realized
quickly and economically fulfilling high designing
requirements.
Like a veil the semi-transparent suspended cable façade
covers the building. The façade consists of prefabricated
cable elements, hanging in round timbers prepared by system
holders. The round timbers are made of Oregon Pine, turning
into a silvergrey colour over the years due to being directly
exposed to weather.
Clips of stainless steal are mechanically fixed on the
prefabricated cable elements. They are of punched plate and
act as system holders. To the various floors of the parking
level the cables are fixed by swinging clips in horizontal
direction in order to reduce the deformation caused by wind.
The pergola is constructed analog to the façade, the various
cables being stretched from the reinforced concrete core to
the outer compression ring. With two additional steel rings,
concurrently serving to hold the lighting, the dynamic
deformation of the system is statically appeased and
stabilized.
The attention and acceptance this building receives is as well
due to the fact that it functions as a public space: open, light,
beautiful, inviting.
