La Poterie Transit Hub

The main objective was to improve La Poterie transit hub operations, to increase its capacity, functionality and adaptability to new transportation requirements but also to give the hub the ability to extend; in particular, the bus station.

Infill site on city urban front.

Consequently, it was decided:

- to increase car park capacity by building a superstructure car park on the lawn site to the south (693 car spaces including 313 additional spaces);

- to increase bus station capacity to accommodate additional STAR services and bus stops in the Illenoo network (departmental public transport);

- to commission the existing entrance to the park and ride facility on Rue de Vern for traffic entry and exit of the facilty and convert the existing access to exit only;

- to develop the existing car park for new traffic circulation and uses; and

- to assure road user safety at the park and ride facility new entrance.

Design intent is expressed by the parallelepiped form with its cylindrical ramp.

To cope with the infrastructure environment, construction materials are limited to concrete, timber and steel.

Architectural concrete is used at the base of the main building with V-shaped columns surrounding the entire structure to give it both independence and visual continuity.

On the south elevation, grill with mesh panels act as a guardrail.

Naturally ventilated parking structure has a grey concrete internal finish.

On levels 3 and 4, larch timber blades were installed in elevation to act as guardrails. The kiss and ride waiting and entrance pavilions have the same finish in elevation.

A photovoltaic panel sunshade was installed on the intermediate section on the uppermost level of the covered car park. Its frame is simple, a galvanised “over-roof” with lighting built in.

Site context both outside the master plan and outside the system

The transit hub site is vast yet intimate as if enclosed by embankments. To connect the city to its inner suburbs, it takes into account access constraints and the adjoining motorway.

Major alterations to the road layout reconfigure soft means of transport.

A new vegetated pedestrian pathway is created between the parking lot and La Poterie metro station, designed in 2002 by architect Norman Foster

Mobility is at the heart of site regeneration, to ensure traffic safety and facilitate exchanges.
