What IBA27.de does

IBA'27 (legal name: Internationale Bauausstellung 2027 StadtRegion Stuttgart GmbH) is a publicly backed urban-development exhibition organization headquartered at Alexanderstraße 27, Stuttgart, Germany. Founded in 2017 as a private limited liability company (GmbH), it is preparing a major building exhibition in 2027 timed to coincide with the 100th anniversary of the 1927 Weissenhof architectural exhibition. IBA'27 curates a portfolio of 32 official projects spanning municipalities across the Stuttgart region (Stuttgart, Fellbach, Waiblingen, Backnang, Wendlingen, Sindelfingen, among others), focused on sustainable construction, circular building practices, innovative housing, and community-oriented urban renewal.

The organization operates as a coordination and curation platform rather than a product company. Its 'products' are the curated project portfolio, the Circular Construction Hub knowledge platform, festivals (Festival #1 in 2023, Festival #2 in 2025), plenums, competitions, the IBA'27-School educational program, and a publishing/news operation across web and social channels. It does not offer commercial software, SaaS, or technology products. Implementation is delivered through a network of architecture firms (e.g., 4a Architekten, RIEHLE KOETH), construction companies (ZÜBLIN, Wolff & Müller, Blumer Lehmann, Bässler Projektbau), housing developers (Siedlungswerk), and modular specialists (Pool out of the Box).

IBA'27's business model is non-commercial: it is funded through public subsidies, sponsorship, and partnership contributions, primarily from Land Baden-Württemberg, Landeshauptstadt Stuttgart, and Verband Region Stuttgart, with additional support from construction-sector sponsors and media partners. There is no disclosed pricing model and no published revenue figure. Leadership comprises Intendant Andreas Hofer, Managing Director Dr. Gabriele König, and Commercial Managing Director Karin Lang, supported by project managers and a Supervisory Board and Board of Trustees.

Direct peers

• Deutsches Architekturmuseum (DAM): Germany's leading architecture museum in Frankfurt, which parallels IBA'27's exhibition role in elevating architectural and urban development discourse. Both institutions use exhibitions as the primary vehicle for public engagement around building culture.
• Architekturzentrum Wien (Az W): Vienna's architecture center curates exhibitions, publications, and events on architecture and urban development, operating a similar exhibition/curation model to IBA'27. Both organizations bridge the gap between professional architecture and public engagement.
• IBA Emscher Park: Historical IBA in the Ruhr region (1989-1999) that pioneered the modern IBA format for structural regional transformation. While no longer active, it is the direct conceptual ancestor of the current IBA format used by IBA'27.
• IBA Berlin: Berlin's IBA (2017-2020) used the same International Building Exhibition format with a focus on social urban development and innovative housing. It provides a comparable case study in time-bound IBA execution and post-exhibition transition.
• IBA Thüringen: Thuringia's IBA is a more recent building exhibition using the same IBA format, focused on rural-urban development challenges in the region. Active and conceptually aligned with IBA'27's approach to using building exhibitions as regional transformation tools.
• IBA Hamburg GmbH: Hamburg's IBA (2013-2022) used the same international building exhibition format for metropolitan urban transformation along the Elbe islands. It provides a directly comparable operational template, including thematic focus on sustainable construction and participatory urban development.
• IBA Basel 2020: Swiss IBA using the same IBA format for cross-border trinational urban development in the Basel region. Comparable in scale, public-private partnership model, and exhibition-driven approach to regional development.
• IBA Wien: Vienna's International Building Exhibition (IBA Wien) uses the same IBA format for sustainable urban development, with a similar 2022-2027+ timeline. It is the most directly comparable active peer in the IBA network, addressing shared themes of housing affordability, social cohesion, and climate-responsive urbanism.

Regional players

• StadtBauKultur NRW: Regional building culture foundation in North Rhine-Westphalia with a similar mission to Stiftung Baukultur Baden-Württemberg (an IBA'27 partner). Operates in a different German region but addresses comparable themes of urban development quality and public engagement around building culture.

Broad incumbents

• Bundesstiftung Baukultur: National building culture foundation in Germany that operates across the broader building culture agenda, including urban development, public engagement, and policy advocacy. More established and broader in scope than IBA'27's regional focus, but the most relevant national organization addressing similar themes.
