Last update: November 2025
The backbone of building: a deep dive into Luxembourg’s construction landscape
What does Luxembourg’s construction sector really look like beneath the surface? Luxinnovation’s panorama of the construction ecosystem and accompanying facts & figures report offer a fresh, data-powered lens on one of the country’s most dynamic industries.
With over 3,500 organisations mapped across five key stages: design & planification, suppliers, construction, operation and end-of-life & circularity, this edition provides a broad and practical overview of the value chain, based on available data and expert filtering.
It reflects Luxinnovation’s commitment to supporting innovation and collaboration within the sector.
Luxembourg's construction value chain
The Luxembourg construction ecosystem comprises 3,593 organisations distributed across five key stages of the value chain. The construction phase dominates with 2,174 organisations, reflecting the sector’s strong operational focus on building activities.
In contrast, the end-of-life & circularity segment counts just 14 organisations active in dismantling, recycling, and material reuse. This representation highlights a potential gap in circular economy practices and signals an opportunity for growth in sustainable deconstruction and resource recovery.
Overall, the data reveals a sector heavily weighted toward construction execution, with emerging needs for lifecycle management and circularity to align with sustainability goals.

A dominance of smaller organisations
