Rondo, Contemporary architectural structure in Lend district, Graz, Austria.

Rondo is a seven-story building completed in 2007 in the Lend district, designed by architect Markus Pernthaler. Its curved front was clad in a translucent membrane of polycarbonate panels, and the arc is divided into three sections, A, B and C, along Hans-Resel-Gasse, Marienplatz and Mühlgasse. It holds 66 apartments of about 90 square metres and 10 office or shop units of 200 to 800 square metres.

The building was completed in 2007 on a site that previously held a mill called Marienmühle. The mill had closed in the late 1980s and the land stayed empty until this development transformed it into an active residential and working neighborhood.

On the fourth floor are eight work studios, allocated yearly, and four live-in studios, allocated every six months, by the Instyria Kultur Service Gesellschaft through an open call. They are free of rent, financed by the City of Graz and the State of Styria; artists pay only operating costs. The scheme is meant to foster exchange between disciplines.

The building is easily walkable in the Lend district and has multiple entrances serving different areas. The surroundings are accessible for exploring the exterior and observing the architectural features from street level.

The building encloses an old park crossed by the Mühlgang stream, where a pavilion by architect Herbert Eichholzer stands; Eichholzer was executed by the Nazis in 1943 and is regarded as a symbol of resistance. Large parts of the violet facade were torn from their anchors and fell into the street during a storm on 27 January 2008.
