Gudenauer Weg 134–136, Government building in Ippendorf, Bonn, Germany.

Gudenauer Weg 134-136 is a government building in Ippendorf, Bonn, comprising four interconnected wings spread across approximately 42,000 square meters of floor space. The structure features terraced levels with green rooftops and sits at an elevation of about 173 meters.

The training academy was designed by Bonn architect Ernst van Dorp with Karl Rudolf Hautz after their 1966 competition win; planning began in 1967, the topping-out was celebrated in August 1971, and the building opened on 7 June 1973. It served the Foreign Office until the staff moved to Berlin-Tegel at the start of 2006. A renovation and extension costing seven million euros followed from 1992 to 1995.

The site has stood empty since the Foreign Office training academy moved to Berlin-Tegel at the start of 2006, so the grounds are not open to visitors. The garden laid out after the 1992–1995 extension follows Japanese models. In 2021 the complex served as a filming location for the series How to Sell Drugs Online (Fast).

The complex has stood empty since the Foreign Office training centre moved to Berlin-Tegel at the start of 2006, and proposals for reuse by other federal bodies have so far failed. The 1995 extension was fitted out in 2016 as emergency accommodation for up to 50 refugees. The site lies on the southern edge of Ippendorf by the Kottenforst, at about 173 m above sea level; the grounds are not open to visitors.

Architect Ernst van Dorp designed the building with a dual-purpose concept that allowed for potential conversion into a hotel while maintaining administrative functions. This flexible design strategy was unusual for institutional buildings of that era.
