Romabau

What Romabau does

Roma-Bau S.A. is a privately held Luxembourg construction and real estate development firm headquartered in Weiswampach, founded in 2000 by Robert Schrauben after 15 years of prior industry experience. The company operates as a general contractor and developer, offering turnkey residential construction (Maisons clé en main), solid construction (Constructions massives), structural work (Gros oeuvre), real estate development (Promotion), property sales (Immobilier — houses, apartments, and building plots), and exterior landscaping services (Aménagement extérieur). Its core technology stack combines traditional solid construction (Massivbau) with computer-aided planning, 3D visualization/simulation for project previews, and energy-efficient Passivhaus construction standards including air/water heat pumps and integrated ventilation systems. Specific developments include the "In der Oicht" 17-plot subdivision in Reisdorf and the Moestroff double-residence project (10 apartments) developed in partnership with LANDLORDS INVEST.

The business model is project-based and transactional. Roma-Bau generates revenue through one-time construction contracts (turnkey delivery with single point of contact from planning to completion), property and land sales (transaction fees), and add-on landscaping services. Pricing is per-unit/contract: building plots range from €179,000 to over €505,000, with a €35,000 surcharge for plots purchased without construction contracts; the Moestroff development project is priced at €1,250,000. The company guarantees budget adherence with no hidden costs. Go-to-market is sales-led and direct: customers engage via website contact forms, phone, office visits, bilingual French/German service, and annual Open House events. Customer segments comprise individual/family homebuyers (primary), real estate investors, and agricultural/business owners needing specialized construction.

The company is family-controlled: Robert Schrauben serves as founder, owner, and managing director, with Marlyn Schrauben-Heirens handling accounting. No external investors, parent company, or PE backing was identified. With 60+ employees and 600+ completed projects over 30+ years, Roma-Bau is a mid-sized regional operator with operations confined to the Grand Duchy of Luxembourg.

Broad incumbents

• Eiffage Construction: Major French general contractor and developer active across residential, commercial and civil construction; overlaps with Roma-Bau on turnkey housing delivery and energy-efficient builds in neighboring markets.
• Bouygues Immobilier: Major French residential and commercial property developer combining land development with construction, comparable in value-chain integration though operating at significantly greater scale and broader geography.
• Strabag Real Estate: European construction group with a dedicated real estate development arm focused on residential and mixed-use projects; comparable integrated design-build-and-sell model though operating across multiple European countries.
• Vinci Immobilier: Residential and commercial real estate developer within the Vinci group, with a comparable develop-then-build-then-sell model across France and selected international markets.
• Implenia: Swiss general contractor and real estate developer combining construction services with own-account development — same integrated residential pipeline model as Roma-Bau, but at pan-Swiss scale.
• Kaufman & Broad: French for-sale homebuilder and residential developer with a design-build + subdivision business model analogous to Roma-Bau's integrated construction-plus-promotion offering, but operating at national French scale.
• Nexity: France's largest residential developer, active across new-build housing, serviced residences and property sales — a much larger incumbent executing the same land-to-home pipeline Roma-Bau runs in Luxembourg.

Others

• Coficiel (Compagnie Financière pour l'Immobilier et la Construction en Europe): European real estate development and investment vehicle active in residential projects across Benelux-adjacent markets, useful as a comparable for cross-border residential development economics.
• Saint-Gobain Habitat: Building materials supplier and renovation solutions provider adjacent to Roma-Bau's residential construction activity; relevant as a materials and energy-efficiency partner rather than a direct competitor.

Direct peers

• Felix Giorgetti: Luxembourg-based general construction and civil engineering firm with a comparable mix of building, infrastructure and real estate development activity in the Grand Duchy, competing for the same residential and developer clients.
