Hanns-Seidel-Haus, High-rise building in Freimann district, Munich, Germany.

Hanns-Seidel-Haus is a twenty-storey high-rise opened in 1973 in the Neustadt of the Studentenstadt Freimann, Munich. It is just under 60 metres tall, 65 metres long and 20 metres deep, and holds almost 620 single apartments for students. The building was designed by Ernst Maria Lang, who won the architecture competition in 1960 with the Lang und Pogadl partnership.

The building was realized after architect Ernst Maria Lang won a design competition in 1960, working with his partner Pogadl on the project. This tower became emblematic of Munich's post-war residential expansion in the Freimann district.

The building is named after Hanns Seidel, a former Bavarian minister-president. Its nickname, the "green house", comes from the colour of the facade. In 2015, artist Florian Freier paired photographs of lived-in apartments with their residents' Facebook profile pages in a series of 100 photo-screenshot combinations, published online and as a book.

The building features three elevators that provide convenient vertical access to all floors for residents. The location includes good connectivity and amenities that support daily living in this residential complex.

The rooftop terrace held a non-public facility called Manhattan, the highest beer garden in Munich. It was reserved for residents rather than open to the public, so the view over Freimann stayed inside the student housing community. The building is named after Hanns Seidel, a former Bavarian minister-president.
