KUHN CONSTRUCTION S.A.

What KUHN CONSTRUCTION S.A. does

KUHN CONSTRUCTION S.A. is the oldest family-owned construction and real estate development company in Luxembourg, founded in 1897 and now led by Roland Kuhn in its sixth generation. Operating under the broader Groupe Giorgetti (since the 2006 alliance with Félix Giorgetti Sàrl and the July 2024 merger with Pianon S.A.), the company is part of the largest construction group in Luxembourg. Kuhn runs eight integrated departments: Gros œuvre (structural works), Génie civil (civil engineering), Façades, Petits travaux (small works), Aménagements extérieurs (exterior developments), Entreprise générale (general contracting), Développement immobilier (land analysis and co-development advisory), and Promotion immobilière (real estate development and sales via the Kuhn Immobilier sub-brand with 135+ listed units). Technologically, Kuhn leverages Green Stone Luxembourg's Poroton® prefabricated masonry walls (used since 2021 to roughly halve build time), demolition robots and mobile cranes for constrained urban sites, and has pioneered clay wall construction in Luxembourg through a partnership with German engineering firm ZRS.

The company serves a diversified mix of public institutions (Ville de Luxembourg, SNHBM, Bibliothèque Nationale du Luxembourg), private commercial clients (Artea, Post Luxembourg, Smart Communication Agency), heritage-building owners (Hôtel des Postes reconversion), and individual property buyers through direct-to-consumer marketing of its development portfolio. Approximately 1,000 projects are completed per year by a 420-person team, with cumulative delivery of 125 million m² of habitable surface over 125+ years of operation. All activity is domestic to Luxembourg, with no disclosed international operations.

Kuhn earns revenue through project-based construction contracts (gros œuvre, façades, civil engineering, turnkey delivery), property development and direct unit sales via Kuhn Immobilier, and professional services for landowners seeking joint development. Pricing for construction services is quote-based and not publicly disclosed, while real estate units are listed on the company's website with publicly visible prices ranging from approximately €86,000 for entry-level units to over €2.6 million for luxury residences. GTM is hybrid: enterprise field sales and competitive tendering for institutional/developer clients, and a DTC website portal plus direct consultation for property buyers. Distribution is exclusively through direct channels within Luxembourg.

• Eiffage Construction: Major French construction group with a Luxembourg subsidiary. Offers general contracting, civil engineering, and real estate development comparable to Kuhn's full-service 360° platform, but at significantly larger European scale.
• Demathieu & Bard: Large French construction group with established Luxembourg operations. Competes with Kuhn on larger public infrastructure and nonresidential construction projects, while operating from a much broader European footprint.
• CFE Group: Belgian construction group (subsidiary of Ackermans & van Haaren) with significant activities in Luxembourg through CFE Luxembourg and BPC Group. Competes in residential, commercial, and civil engineering categories.
• VINCI Construction: Global construction leader with a long-standing Luxembourg presence. Competes especially for large public infrastructure projects and institutional building works; partially comparable in real estate development through adjoining VINCI Immobilier.
