The project for the Nature Museum St. Gallen is conceived as a continuation of the surrounding landscape, an interplay between building mass and topography. Similar to a tectonic shift the volume is divided in to two mutually deformed parts. The resulting plan figure orients itself along the two dominant urban axes: the main road to Rohrschach and the diagonally crossing highway A1. The staggered volume of the building defines clear exterior spaces and anchors the building in its urban context.
Inside, the landscape theme is continued seamlessly. Led by vistas into the surrounding scenery the visitor moves upwards on a spiral, a flowing, and continuous exhibition experience with no interruptions by walls or slabs. Instead, topographically shaped floor plates and the concrete walls of the supporting facade and core define a suspenseful sequence of differently proportioned spaces. The large, slit-like openings with their deep embrasures allow adequate daylight into the building without damaging the exhibits.
