Showroom building for the automotive
industrial branch
The building's design is based upon a contentual and spacial exhibition
concept, which as base for the shape finding was developed by the architects
first.
As a result, architecture and exhibition form an inextricably unified whole.
Conception of the site
The new exhibition building at a corner plot represents the prospect into the
MAHLE area and is at the same time a landmark for the passage into the
adjoining quarter. The building being a sculptual object in public space
provides the undefined space in between Halden- and Glockenstrasse with a
setting and arbitrates between the height grading of urban industrial areas and
the directly adjacent mixed used area.
Exhibition
By its company exhibition on four floors and
approximately 1200m² of exhibition space, MAHLE provides staff, clients and
visitors with insights into the heart of the company, its know-how and
products, history and employees. The exhibition is developed as a space
continuum organized across four floors.
Coherencies and vistas form relations
between all technical issues concerning the construction of motors in all spatial
axes.
Building Conception
The plain, broadly enclosed building forms the shell for a complex system of
rooms with differing proportion and impression which are affiliated to each
other by plenums and visible relations. Thus the spacial conception of the
house illustrates the sophisticated relations between the exhibition
subjects.
By a system of plenums, gaps or intersections each spacial-thematic
level refers to the following one; thus a floating, natural sequence of rooms
allows the visitor to experience the building in its entirety.
The inextricable
interplay of research, development and production is thus comprehensibly
illustrated by the spacial conception of the house.
Seminar Area
Being the company's vital information- and communication pool, the museum
comprises a ground floored affiliated seminar area which - in combination with
the auditory located in the foyer - provides additional education rooms with an
extensive supply area. Thus the seminar area represents the point of
intersection between museum and plant grounds by simple means.
Facade
The content-related aspects of the house are already conveyed by the building's
exterior: The material stacks, beadings and interstices characteristic for the
constructional principles of motor building as well as the differing finish of
metallic surfaces as symbol of a "technical surface" are translated
into an abstracted system of metal panels of differing haptic and structure.
These are arranged and combined by a matrix of joints in various heights. The
building's storyness is covered up; the house becomes a " sculptural
object" in public space.
The construction which appears almost completely
enclosed during the day, at night-time reveals the apertures which hide behind
the transparent perforated metal plate panels. In the twilight they form a
second facade with a structure that also refers to the technical volume of the
exhibition.
Construction
Walls, ceilings and stairs were mainly made in cast-in-situ concrete
construction. All ceilings stretch unsupported from wall to wall. The ribbed
slab above the ground level consists of pre-assembled component joists and
filigree ceiling elements in cast-in-situ concrete bond. The ceiling above the
second floor is suspended across the roof surface by a steel composite beam;
the ceiling's edge, which is independently continuous for 20.0 meters, thus
does not need any additional support.
Being adjacent to the public road space,
the full cellar building needed to be made of water-proofed concrete with
gunite-sheeting as "stay-in-place formwork" and, due to its location
in a mineral water protection area, founded upon 50 auger piles (1200 mm in
diameter).
Roof
As from higher located urban districts a view onto the roof surface is
possible, it forms the "5th facade"; therefore the design of this
space required special attention. The covering system made of sheet metal
panels and joints is led on across the roof surface area; the drainage of water
is achieved by using the joints.
Energetic Conception
To keep the service and investment costs of the variously intense used building
low, the house, analogous to its storey-overarching conception, is not equipped
with floor-by-floor ventilation, but solely provided with fresh air according
to the current usage intensity in the ground floor. In a natural streaming
course through the remaining air spaces of the level-wise offset ceilings it is
then directed to the top level. On each level, the air is centrally exhausted
and transported to a preheater.
