Protected as a historic monument, the Halle 53 is one of the most striking witnesses of Winterthur's industrial history. Built in 1891 as a large foundry for Sulzer, it is, until today, the centerpiece of the present Sulzer headquarters.

Urbanistically, the large hall acts as a link between the Katharina-Sulzer-Platz in the east and the Drehscheibenplatz in the Lokstadt neighborhood.

In essence, its proposed conversion consists of installing a platform in concrete cast in situ. This structure with four precisely implemented axes within the passage of the front section and the "Grande Salle" neatly dissects them into two areas, mediating the acoustic, climatic, and functional spatial demands while maintaining the visibility and experience of the "Grande Salle's" original three-aisled structure.

The unheated hall emerges as a versatile cultural structure separated from the rest of the complex. Signage on the floor creates space for a variety of scenarios and performances. At the same time, the hall is an urban and public passageway, attractively linking the two city squares.
