What BIG does

BIG (Bundesimmobiliengesellschaft m.b.H.) is an Austrian federal real estate company wholly owned by Österreichische Beteiligungs AG (ÖBAG), the state holding entity of the Republic of Austria. Realised in its current statutory form under the Federal Real Estate Act (Bundesimmobiliengesetz) in 2001 and headquartered in Vienna (Trabrennstraße 2c, 1020 Wien), the firm owns and manages a portfolio of 2,028 properties spanning 7.8 million m² with a fair value of EUR 18.9 billion and total assets of EUR 20.7 billion (Annual Report 2025). Its mandate is the lifecycle management of public-purpose real estate: ~400 schools, more than 200 university buildings serving all 22 Austrian universities and the Austrian Academy of Sciences, ~800 special properties (prisons, courts, Ministry of Interior facilities), and, through its wholly-owned subsidiary ARE Austrian Real Estate (founded 2012), ~590 office and residential properties in integrated urban developments. Approximately 500,000 people enter and exit BIG buildings each day.

The company is structured around four operating divisions — Schulen (Schools), Universitäten (Universities), Spezialimmobilien (Special Properties), and Objekt & Facility Management (OFM) — plus Bau- & Projektmanagement for construction project delivery, supported by 12 OFM regional teams and six state-level school offices. The technology stack is a conventional enterprise real estate management platform covering portfolio and asset management, construction and project management, facility management, and an e-invoicing portal (erechnungen.big.at) compliant with EU Directive 2014/55/EU. A dedicated Energie & Nachhaltigkeit function coordinates a EUR 2 billion decarbonisation programme to 2040, and the BIG ART programme integrates permanent and temporary art installations across the portfolio. The firm follows the Austrian Code of Corporate Governance and is led by two Geschäftsführer (Gerald Beck and Christine Dornaus) under a supervisory board chaired by Klaus Kumpfmüller.

BIG's revenue model is built on three streams: (1) recurring rental income from public sector tenants, dominated by the Federal Ministry of Education (BMBWF), 22 universities, the Federal Ministry of the Interior (BMI), and the Federal Ministry of Justice (BMJ); (2) construction and project management services for new builds, refurbishments, and historic renovations, including landmark projects such as the JKU Linz Juridicum, the University of Vienna main library, the Ballonhalle for the Academy of Fine Arts Vienna, and the Bildungscampus Klagenfurt; and (3) facility and object management services delivered through OFM. Group revenue of EUR 1.6 billion (Annual Report 2025) is supported by EUR 1 billion of annual construction, refurbishment, maintenance, and decarbonisation investment, securing or creating approximately 9,300 jobs annually across more than 2,000 local construction companies. There is no commercial sales motion; all demand generation is institutional, through direct government contracts, public tenders, and architectural competitions.

Scale indicators15 records

Recent moves7 records

Expansion highlights2 records

Broad incumbents

• CBRE Group: Global commercial real estate services and investment firm offering asset management, project management, and facilities services across institutional and government clients. Overlaps with BIG's portfolio and facility management capabilities at much greater scale and commercial breadth.
• Jones Lang LaSalle (JLL): Global professional services firm specialising in real estate and investment management, including government and public-sector advisory. Comparable to BIG on the asset management, project management, and FM service lines but operating commercially across many geographies.

Direct peers

• Statsbygg: Norwegian government's key advisor and manager of public property, owning and developing state buildings including universities, cultural sites, and government offices. Comparable in mandate, public ownership, and integrated construction-management role.
• Senaatti-kiinteistöt (Senate Properties, Finland): Finnish state-owned real estate company providing work environment and property services to government agencies, research institutions, and universities. Operates under a similar federal mandate model with university properties as a core segment.
• Bundesanstalt für Immobilienaufgaben (BImA): Germany's federal real estate agency, managing federal properties including administrative, military, and educational buildings. Most direct structural analogue to BIG as a state-owned portfolio owner and developer for federal clients in a neighbouring DACH market.
• Direction de l'immobilier de l'État (DIE): France's central state real estate directorate managing the federal property portfolio, optimising state-owned property use, and overseeing construction and refurbishment of government buildings. Matches BIG's institutional owner-manager role.
• Rijksvastgoedbedrijf: Dutch central government real estate agency managing offices, courts, prisons, and educational buildings for the Dutch state. Closely matches BIG's mandate of owning, developing, and managing a state property portfolio across institutional use cases.
• UK Government Property Agency: UK executive agency managing the central government estate, including office consolidation, property transactions, and government workplace strategy. Direct peer in delivering real estate services to federal ministries on a national scale.

Regional players

• Immofinanz AG: Vienna-based commercial real estate company owning and developing office and retail properties across Austria and CEE. Provides regional comparison on Austrian property investment, asset management, and development economics relevant to BIG's ARE subsidiary.
• CA Immobilien Anlagen AG (CA Immo): Austrian real estate investment company focused on office properties in major CEE cities, with significant presence in Vienna. Comparable Austrian regional player in commercial office development, asset management, and project management, though without BIG's public-sector mandate.
