The image of
Rossignol, a historic leader in the world of skiing, is intimately linked to the
mountains and to snow. The project for its global headquarters has nothing to
do with the stereotypical office building, but is a tribute to nature and to
the peaks, but also to technology, which is inseparable from top-level sport.
The plot stands
in the middle of a plain surrounded by mountains. It is a stretch of former
farmland, marshy and perfectly flat, bounded on the northern side by the Lyon-Grenoble
motorway. The architecture has been designed specifically for Rossignol, a
fusion of the company’s functional and fantasy aspects, in a surprising and
minimalist form: it is inspired by board sports, by fluidity of motion, and also
by relief, snow and glaciers sculpted by the elements. The roof, which envelops
the whole project, is topography in osmosis with nature and the landscape. Its
organic, timber-clad shape echoes the profile of the mountains that surround
the site.
In order to
create the “House of Rossignol”, the Rossignol Group will be assembling on these
site different entities that are currently spread over several locations, but
which all contribute to the company’s identity.
The roof covers
three types of space:
-
The racing ski production workshop,
the brand’s technological showcase, and technical rooms, all grouped alongside
the motorway.
-
The office floors, which include the
administrative and sales departments, R&D, research and design, etc.
-
The street, spectacular and bright,
the space of social encounter, which crosses the building from side to side. At
its end, the street widens to become the showroom.
On the motorway
side, the facade creates a kinetic and dynamic effect reinforced by the
repetition of the logo, which appears gradually. The front of the building
rises to form a roof over the workshops and then on to the apex, and descends
again on the south-western side to cover the office area. It is then intercut
with patios planted with birch trees that seem to grow through the roof: nature
and building intertwine. The irregular profile of the roof and office facades
leaves the opportunity for future extensions as required. Additions can be
built without disrupting the balance and identity of the project. From the
start, the architecture embodies its own growth process. The roof ridge, with a
glasshouse running along it, is situated above the street, a high-level space
giving onto the “high-altitude restaurant”, the highest point of the structure,
which refers to ski slope restaurants.
Inside, the
building functions like a “hive” in which the different functions come into
contact and interact, where people enjoy the experience of working together and
meeting each-other. The originality of the programme is that it assembles very
different functions, from production to services, under a single roof. The aim
of this assembly is to create a global synergy which eliminates barriers
between design, service and technology. Each person in their own diversity –
engineer, designer, technician, secretary, salesman, etc. – meets in a
reciprocal encounter. To encourage this internal communication, social spaces
are distributed around the building. The restaurant, situated right at the top
and at the gravity centre of the street, is designed as the primary locus for
the company life: two great glass-roofs divide up the panoramic views to the
sky and the mountains, on one side to the Vercors and on the other to the
Chartreuse. A large roof terrace is available for alfresco lunching, protected
from the noise of the motorway. Whether on the terrace or around a wooden fire,
the restaurant turns the midday break into a special moment.
Only two
materials are used for the external envelope: wood (natural larch) and glass.
The structure is made of steel, like an organic skeleton that outlines the
shape, with its multiple warped surfaces. The roof frame is visible in the
workshop and offices. The post and beam frame of the service floors straddles spans
of 12 to 15 metres
to leave the space as free as possible. The workshop space has a primary
horizontal roof overlaid by the timber over-roof, creating a hidden space
between the two which contains all the technical systems and machinery. This
means that no technical elements are visible from the outside; therefore the
external shape is pure. The building is
designed for minimal environmental impact. The technical choices make it an
efficient and energy-saving building, well insulated and protected from the
summer sun by the timber over-roof. The systems are optimised – the heat
produced by the workshop machines is recovered and re-injected into the heating
network. The offices receive natural ventilation through automatic window
opening.
