Since 1903, the BDA has brought together independent architects and urban planners distinguished by the exceptional quality of their work, their personal integrity and collegiality and their shared commitment to Baukultur and professional performance. All members are appointed by the Regional Associations. The more than 5,000 members of the BDA are among the leading independent architects in Germany. Their track record of success speaks for itself: every third Euro invested in German construction is invested in a project involving a BDA architect. The BDA appoints only members whose character and work meet strict criteria; appointment in the BDA is both an honour and a recognition of high-quality work.
