– Registration in the ZAC Gare, creation of a new district, new centrality. To echo the architecture of downtown Laval. A Laval building, contextualized, which cannot belong to any station district.

– To create an innovative, high-performance building while using simple implementation, know-how and local materials.

– Passive building: optimize solar gain (manage glazed surfaces and provide external solar protection). Work on a highperformance envelope.

– A building in the image of Meduane Habitat: head office of a lessor: durability, sustainability, sobriety. A united company: interconnection between the different departments. Multiple spaces to cross paths and meet.

– A pleasant work environment: bright spaces, flexibility of the plan, informal work spaces (new ways of working).

Architectural Party

– Volumetry in tiers:
– Friendly distance from the buildings on Rue des 3 Régiments
– Offer views of the historic city center, relaxation and break areas on almost every floor
– External staircases: to create links and porosity between the different departments. The unity of the company.
