The Bauwende Allianz is a Germany-focused, missions-oriented movement working to transform the construction and housing sector into one that is climate-positive and socially just.1 It brings together active and future “transformational changemakers” from across the built-environment ecosystem to coordinate action, build alliances, and move from discussion to implementation.12
Its core purpose is to connect ecological construction goals with housing justice. The organisation argues that the building sector is central to Germany’s climate, biodiversity, resource, and affordability challenges, and it frames the “construction crisis” and the “housing crisis” as parts of the same systemic problem.1 The group’s public materials emphasize reducing land take and sealing, prioritizing existing buildings and conversion over demolition and new build, normalizing biological and circular building products, and enabling long-term affordable housing.3
The Bauwende Allianz operates through network-building, policy work, and practical demonstration projects. Its manifesto describes a broad coalition spanning planning, development, construction, use, finance, politics, legislation, research, education, media, associations, and civil society.2 It also notes that the initiative is intended to bring people into joint action through focused alliances and implementation projects.23 The organisation’s website highlights a “Policy Lab 2025,” indicating an active agenda around policy development and sector transformation.1
Geographically, its work is national in scope, centered on Germany.13 The organisation is presented in source material as an initiative of ProjectTogether, and one document lists ProjectTogether’s Berlin address as the mailing/organizational location associated with the Bauwende Allianz.2 The available sources do not identify a separate standalone headquarters beyond Berlin, and no founding year is explicitly stated in the provided materials.2[
