The Federal Office for Building and Regional Planning (BBR) is a higher federal authority within the portfolio of the Federal Ministry of the Interior, Building and Home Affairs (BMI). On the one hand, the BBR looks after federal buildings at home and abroad and, on the other hand, supports the federal government with technical and scientific advice in the policy areas of spatial planning, urban development, housing and construction. The range of tasks extends from large construction sites to spatial planning and urban development model projects, from questions of building culture and monument preservation to questions of European cooperation and from architectural competitions to regional planning reports and housing market studies. The implementation of specialist events and the issuing of own publications round off the broad spectrum.

The Federal Office was established on January 1, 1998 through the merger of the Federal Research Center for Regional Studies and Regional Planning (BfLR) with the Federal Building Directorate (BBD). With the reform of the Federal Building Administration on January 1, 2004, the Federal Building Offices I and II of the Berlin Regional Finance Directorate were also assigned to the BBR. The Bundesbaugesellschaft Berlin (BBB) ​​was integrated on January 1, 2009. The four construction departments of the BBR oversee the most important federal buildings in Germany and abroad as well as the building work of the Prussian Cultural Heritage Foundation in Berlin.
