The challenge of the project of William
Rappard center expansion lies in the difficulty to integrate at once an
exceptional landscape context, and an existing pronounced architectural
style, as well as to be able to answer the functional demands of the
competition.We have chosen to locate the new building as far as
possible from the old one, thus avoiding the relationship of visual
continuity, the new architectural design being independent.The connection between the two buildings will be made light and transparent.This choice is justified by the necessity to maintain natural light in the southern offices of the existing building.Outside:Architecture merges into the landscape. A
design made by lightness, thanks to glazing surfaces and finely
textured steel. This is the type of design that blurs the tangible
limits of the building, making a solid reading of the volume
unnecessary, creating a soft and evanescent image.Facades
define themselves by two glass layers, each one answering to specific
needs and at the same time completing the other one. The first
fine glass skin is covered with a screen-printing film reflecting the
vegetation surrounding the site and creating an effect of visual
penetration. The second "thick" facade meets thermal performance needs.Space between the two allows us to insert a second obscuration system for south facades in summer time.Inside this green frame, everything is overlaid, transparent, reflecting. Everything is light and character. Inside:Landscape penetrates into architecture.A rich, diversified and flexible interior is opposed to the simplicity and compactness of the exterior volume.At
first we worked to define the pixel sizing of the first glazed frame to
have a landscape maximal legibility since workspaces. Then we set up
several devices allowing landscape to penetrate directly into the cone,
the terraces, the common spaces facades and the double heights surfaces.Our
aim was to design a flexible and compact building, a place based on the
pleasure to belong to an elaborated visual world where the quality of
sights and lights becomes a work fulfilment. Common spaces are generously sized and different in every floor.Circulation
areas are also generous and naturally enlightened by the presence of
the light cone, the patio and the light openings of the two levels
outside terraces. The offices built on the periphery allow a
flexibility of organization. In our planning offer we decided to design
the big offices (30 & 25 m�) at the corners of the building.The
architectural, environmental and economic approach, associated with the
will to realize a building proposing wide trays of superstructure
confers an indispensable flexibility to the functioning and future
evolution of the building.
