To implement the IBA, Berlin is establishing a state-owned company, the statement added. Its role will be to prepare and curate the exhibition and to oversee projects through all stages of implementation. A board of trustees comprising experts in urban planning and architecture, environmental and climate protection, sustainability, mobility, digital technology and social affairs will support the new company. “We want to position Berlin nationally and internationally as a hub for sustainable urban development,” said Gaebler regarding the IBA project. “Key areas of focus include the sensitive development of existing neighbourhoods, the conversion of underused spaces and buildings, and new construction on sites previously used for other purposes.”
