In 2007–2008, we collaborated with Polyplan GmbH on the planning of a new Alsterbad in Hamburg. The study focused on the meadow at Schwanenwik, where a modern swimming facility was to be built in place of the historic Alsterbad.

At the heart of the concept was the development of a multifunctional pavilion that can be used for dining year-round. In addition, the ticket office, lifeguard station, and first-aid area were organized into a compact, separate space. When visitor traffic is low, the catering staff can efficiently manage operations on their own.

Concept and Design

The planning area encompassed the year-round recreational and leisure space along the banks of the Alster. The goal was to expand the site’s functionality while preserving its scenic qualities. The plan called for a swimming area separated from the Alster, as well as a clearly defined entrance area featuring a pavilion.

A key feature is a permanently installed pier platform located about 30 meters from the shore. Thanks to its low height above the water and its meandering, varying width, the unobstructed view of the Alster is preserved, and the visual connection to the surrounding natural landscape is deliberately enhanced.

The entrance pavilion at the southern rotunda is designed as a light, linear structure with a curved membrane roof. The roof’s shape evokes associations with waves and sails, giving the building a distinctive yet site-specific identity. A wooden deck in front provides access to ancillary facilities such as restrooms, showers, changing rooms, and lockers, integrating them both functionally and spatially into the overall concept.
