The former Rhein-Main-Donau office block in Munich’s Leopoldstrasse has a new face. Erected in 1929 by Jakob Pfaller and Theodor Fischer, this listed and recently refurbished building now forms the western front of the Allianz insurance company’s headquarters, which extend 400 metres to the east, over two street blocks, to the Englischer Garten. The development comprises two new tracts. The complex at the?western end by the architect Peter von Seidlein incorporates the existing cubic structure in Leopoldstrasse, extending it to the rear with three new blocks that are linked by an elongated, linear tract. This spine-like structure closes the development off to the north, creating a series of courtyards, each of which has its own character. All offices in the new buildings are oriented to these courtyards. The offices are glazed over their full height and are ventilated by natural means. The development is distinguished by consistent, precise detailing throughout, which not only ensures functional efficiency, but lends the complex a calm, homogeneous appearance.
