Haguenau Square forms one of the main gateways of the Strasbourg metropolitan area with its muddle of railroads, a canal, roads and highway entrance and exit ramps. The building called "Maison du Bâtiment" dominates from above the central island developed as an urban park and used as a vast circle for traffic between the center and the periphery.
Looking ahead to 2030, the Phosphore teams propose to enhance this complex and functional city entrance landscape while preserving its specific features. A requalification/extension and a complete energy renovation of the Maison du Bâtiment will extend its working life. A new evolutive construction, the "Hive", will increase the density of the central square which will maintain its function as an urban park and city entrance traffic regulator.
