Is moving to a neighboring country a good way to manage your household's housing costs?
To escape extreme land costs, an increasing number of residents are moving their construction projects to the German Saarland region. This trend allows households to secure significantly larger building plots for a fraction of the domestic price.
Why it matters
Extremely limited land supply and record-high real estate valuations in Luxembourg have made new home construction largely unaffordable for the average family. By moving across the border, these buyers avoid the 800 to 1,200 euros per square metre cost found at home.
Land in German border towns currently costs between 80 and 250 euros per square metre, compared to 800 to 1,200 euros in Luxembourg. With plots in Germany measuring 500 to 1,000 square metres, these savings help keep total building projects between 500,000 and 600,000 euros.
The players
MT Massive Traumhäuser
A Saarland-based building company that reports approximately one in three clients now hails from Luxembourg.
The details
Building a home in the Saarland region allows families to bypass the prohibitive land scarcity currently locking many out of the Luxembourg market. Buyers typically target municipalities like Perl, Mettlach, and Orscholz to maximize their purchasing power. These commuters remain subject to Luxembourg income tax, which requires careful financial planning regarding local German schooling and social services.
Timeline
The trend toward cross-border construction remains ongoing in 2025.
Money Landscape
This migration reflects an ongoing response to the persistent housing supply shortage in Luxembourg, which shows no signs of shifting soon. The trend highlights a sustained divergence in residential real estate costs between neighboring European markets.
If you are evaluating home construction, compare local land premiums against the potential tax and logistical implications of living as a cross-border commuter. Consult with a qualified tax professional to understand how living in Germany while working in Luxembourg affects your net household income.
The takeaway
The primary insight is that geographical flexibility in residential construction can dramatically reduce the land-cost burden for households. Before planning a cross-border move, review your current tax liability as a commuter to ensure the construction savings are not offset by other expenses.
