What SOLUDEC does
SOLUDEC S.A. is a privately held Luxembourg general construction company and real estate developer founded in 1949, operating as an entreprise générale (general contractor) with full all-trade (TCE) capability. The company executes building, civil engineering, and structural works (gros œuvre) for both public sector clients — including government administrations, public housing organizations (SNHBM, Fonds du Logement), and municipalities — and private sector clients such as real estate developers and corporations. Headquartered in Luxembourg (registered office at 4, rue Henri Schnadt) with operational centers in Bascharage and Niederkorn, SOLUDEC holds government authorization No. 36923 and operates a workforce of 159 employees. The company also runs specialized technical and geothermal drilling services through SOLUDEC Energie.
The company operates a vertically integrated business model with two revenue streams. The construction contracting segment generates project-based revenue from lump-sum and cost-plus contracts, with active project values ranging from €4.5M to €55.81M (notably SNHBM AK7-2 at €55.81M, OBH Hôtel Complex at €50.19M, Domaine Thermal Mondorf at €43.19M, and SNHBM AK7-1 at €30.9M). The real estate development arm, operated through wholly-owned subsidiary Soludec Development Sarl (capital €1M, founded 1997), develops and sells residential apartments and villas directly to end-buyers through the company's website, with unit prices ranging from approximately €327,582 (38.81m² office) to €2,335,704 (174m² apartment) at super-reduced 3% VAT. Current active developments include Manhattan at Belval, OPTIMUM at Steinfort, PENINSULA at Grevenmacher, Résidence SKILL at Howald, and Maison BOS at Bereldange.
Go-to-market is sales-led: public projects are won through competitive tendering on Luxembourg public procurement portals, while private mandates and property sales are secured through direct client relationships. The company is geographically concentrated in Luxembourg with no disclosed international expansion, and maintains a relationship-driven, content-supported marketing approach through its corporate website (soludec.lu), press coverage in Paperjam and municipal publications, and limited LinkedIn presence. Owned by Jacques Brauch (Directeur Général), SOLUDEC has no disclosed external private equity or venture capital backing.
