What Wien-Süd does

Wien-Süd is a non-profit housing cooperative (Gemeinnützige Bau- und Wohnungsgenossenschaft) founded in 1910 in Vienna, Austria, and currently headquartered in the Liesing district. The company develops, constructs, owns, and manages residential, commercial, and parking properties across four Austrian states — Vienna, Lower Austria, Upper Austria, and Burgenland — through its parent organization and five wholly-owned subsidiaries (Arthur Krupp, B-SÜD, WSO, Merkur, and Wien-Süd Projektmanagement). Its owned portfolio comprises approximately 25,100 apartments, 500 commercial units, and 24,000 parking spaces, with an additional ~10,000 units managed for external owners, bringing total units under administration to approximately 49,600. The company produces on average ~1,000 new or renovated units annually.

The organization's core products span the full housing lifecycle: Projektentwicklung (project development), Bauleitung (construction management), Immobilienverwertung (real estate sales), Immobilienverwaltung (property management), Hausverwaltung (building administration), and Wohnbeihilfe (housing subsidy assistance). Customers are primarily individual tenants and homebuyers seeking affordable rental or ownership housing, served through a direct-to-consumer model combining a website with property search/filtering, a Vormerkung pre-registration system, customer advisor consultations, and physical offices. Revenue derives from recurring rental income (subscription), one-time ownership unit sales, parking and commercial rentals, and managed services for third-party owners. Pricing is cost-covering and below-market, reflecting the non-profit cooperative structure.

Technically, Wien-Süd is notable for building Europe's first low-energy house (Engerthstraße 257, Vienna) and for delivering Biotope City Wienerberg, the world's first GREENPASS Platinum certified urban quarter with 950+ apartments. The 'Digitaler Hausmeister' digital concierge platform connects residents with staff and neighbors, and a 10-year 'Kunst am Bau' (Art in Construction) initiative integrates contemporary art into developments. The company is a member of the GBV (Gemeinnütziger Bauverein), the Austrian association of non-profit housing cooperatives.
