Luxembourg’s ongoing metropolisation has reshaped territorial development dynamics across the Greater Region, generating strong interdependencies and increasingly specialised functional relationships between neighboring regions. The country’s economic attractiveness continues to drive residential expansion beyond its borders, resulting in intensifying cross-border mobility, growing demand for housing, rising property prices, and heightened socio-spatial disparities. These trends contribute to increased pressure on land resources and expanding urban sprawl.

To address these shared challenges, the 36-month DIALOG project (starting in January 2026) will focus on three key priority areas:

• Sustainable housing and urban development
• Spatial planning
• Access to housing

The project places strong emphasis on co-creation, bringing together public authorities at local, regional, and national levels with scientific partners from all five regions of the Greater Region. By fostering mutual understanding and shared knowledge across borders, the consortium aims to:

• jointly identify the major cross-border challenges linked to housing and urban development
• analyse the cross-border effects of national and local policies
• co-design operational strategies strengthening cross-border territorial governance

Project partners are already aligned on continuing their collaboration beyond the project timeline to ensure lasting impact and continuity.

We already mentioned that in the first sentence that LISER is leading. I suggest adding here the names of the people from LISER involved as well as the names of the financial partners and that: The DIALOG project is strongly supported by the Luxembourg Ministry of Housing and Spatial Planning.
