The site is 150 acres of agricultural land at the edge of Toulouse, near a large international
airport serving the region, and one of the largest and economically important Airbus factories in
the city. The client – Société Publique Locale d’Améngement (SPLA) – has decided to relocate
the existing Parc des Expositions (PEX) in Toulouse from the city centre to this new location in
order to be “closer to the infrastructure and services consistent with economic development of
the city”.
OMA
The new Parc des Expositions has a program requirement of 40,000 m2 of column-free indoor
exhibition space, 41,000m2 of outdoor exhibition space, 15,000 m2 multifunction event hall,
15,000 m2 of logistics & amenities space, approximately 160,000 m2 for parking (6500 spaces),
connection to a future tram extension in the east of the site, and the preservation of an historic
farm. A Phase II expansion has an additional 45,000 m2 of indoor exhibition space and 37,500
m2 of parking.
OMA
In an area best characterized by sprawling and fragmented developments, multi-lane highways,
and leftover spaces, we adopt a strategy that emphasizes compactness and preservation of
open space.
OMA
An east-west axis is defined – creating an off-limit zone for developers – that is marked on the
west by the new Aéroconstellation ZAC development, and on the east by the Garonne River.
This new axis connects existing fragments of development and creates a linear band of
parkland and public amenities including the PEX. Future developments in the adjacent areas
are encouraged by virtue of the amenities of this strip.
We reject the sprawling organization typical of PEX in France – with parking at grade and
exhibition halls as individual pavilions – and adopt a strategy that emphasizes compactness and
density. Three parallel bars of program define the PEX as a rectangular block 316m wide, and
660m long that connects to and activates the public spaces to the east and west. Parking
occupies a central position in the PEX as an elevated six story parking block with a central void
along its length, allowing light and air to the spaces below. This element becomes the main
circulation and organizational device, with exhibition halls to the south and outdoor exhibition
and event halls to the north.
OMA
The lobby has two parts: at grade, it extends in an east-west direction for the length of the
parking block, creating a “mixing zone” for exhibitions and visitors along its length. Near the
centre, escalators bring visitors to an upper lobby that forms part of a north-south band of
amenities connecting the three program bars. In the south, a business/conference centre faces
out on the steps above the exhibition spaces; in the north the lobby connects to the Great hall
upper level, with additional access via escalators to the ground floor. Visitors arriving to the
PEX by car access the upper lobby and can enter either the Event Hall directly, or via
escalators to the lower lobby and exhibition spaces. Visitors arriving by tram enter the lower
lobby on the east side, with direct access to the farm, outdoor & indoor exhibition spaces, or
the Event Hall.
OMA
The structure of the exhibition spaces and Event Hall forms a continuous three dimensional
grid that extends to include the façade and roof, providing a generic “plugin” system for
services and for exhibitors in the exhibition halls. Exhibitor and Truck access to the exhibition
halls is at grade from either the north or south side of the exhibition halls, with the largest
exhibition hall in the southwest having a full height door sliding the length of the façade for
oversize objects.
OMA
The PEX is integrally connected to the open spaces to the west, with the Event Hall having a
large bi-fold door opening toward outdoor seating that allows performances both indoor and
outdoor. To the east, the outdoor exhibition spaces ramp over the highway toward the Phase II extension of the PEX. The farm – preserved in its current state and as part of the exhibition hall
sequence – provides a restaurant and agricultural amenity. Visitors arriving to Toulouse along
the highway enter the city via the PEX as a gateway and exhibition for the city.
