The project started as a won competition for the redevelopment
of the “Zentralplatz”. The program included retail
space, urban functions and a 6.000 m² square.
Urban design concept
The complete program is split into two volumes, separated
by the Zentralplatz. This separation of functions allows for two autonomous and
highly functional buildings, which can develop long-term and independently.
Because of the precise positioning of the buildings and their outline, the
pedestrian flows are organized in an effective and logical way.
Kulturbau
The Kulturbau houses the public library, the
Mittelrhein Museum and the tourist information of Koblenz, with their ‘Zentrum
der Rheinromantik’. The combination of these different cultural institutions
offers the chance to exploit the synergies between the various institutions. The
cultural building stands solitary in the new central square and is a landmark
due to this solitary character, its facade design and the conscious elevation
in the city. The building has splendid accessibility for visitors; the central
lobby has entrances from all sides and is therefore a natural part of the urban
fabric.
On the open square, the three functions each have their
own entrance. Via prominent access elements like the spiral staircases (museum
and tourist information) and the escalator (library), the institutions can be
reached. Above the common ground floor
area, the different functions overlap each other per floor. The permanent
exhibition of the Mittelrhein Museum occupies the first floor.The library is located on floor two, four and five,
with direct access to the roof terrace. The 30 meters high open space inside
connects the institutions vertically, brings day light deep into the building
and offers a variety of outlooks.
The volume
has a double facade with a Structural-Glazing construction of white
silk-screened glass, which envelops the building like a second skin and offers
a frosted and refined appearance. The motif of the print provides a filtered
view from inside to outside, and allows a vaguely transparent view when looking
from the outside in. At the different entrances, the outer facade has a
spacious cut and therefore offers a direct view of the lobby and entrance
areas.
Forum Mittelrhein
The mall
Forum Mittelrhein presents itself as a flat, horizontally layered structure. Due
to this powerful format, the building’s volume is reduced efficiently and a
pleasant sense of scale is established. On relevant junctions within the urban
fabric, the mall offers spacious entrances. The shopping center is
characterized by its trapezoidal layout and smooth outlines. The areas
intertwined with escalators offer orientation points, divide the building and
provide the interior with natural light. Above the stores are adjoining rooms and
a parking lot for about 740 cars. The parking spaces are organized around a
central landscaped courtyard.
Together, the
glass facade on the ground and first floor with standing formats, and the
expressively shaped click frames, give a strong vertical orientation. The top
three floors of the building are dominated by an artificial "Weinlaub facade"
(wine leaf facade). The basis of the structure is an abstract image of a vine leaf,
which is interpreted freely as a 3D-shape. The entire facade is composed out of
only one type of element, that is produced in an industrial thermoforming
process.
