Wagner Design Lab

Project information

A cube with an oversized glass facade, supported on stilts, floating high above the existing residential building – that was the innovative idea of Peter Wagner.

This extraordinary object was realized by Titus Bernhard Architects. It serves as a creative space for the company Topstar GmbH, which specializes in the development and production of high-quality and stylish office seating furniture.

The extravagant building brings design and architecture to the highest level. Almost seamlessly glazed on both long sides, it serves as a showroom for the latest chair collections and a workplace at the same time.

The impressive cube is 48 meters long, 12.3 meters wide, and 6 meters high.

Four insulating glass panels, each measuring 20×3 meters, were used, totaling 60 square meters. They form the north and south sides of the building. These are the largest insulating glass panels ever installed worldwide, manufactured by the company sedak in Gersthofen.
