Getting there and practical details

Neighborhood: Schwendisee, Unterwasser, Toggenburg

The Klanghaus Toggenburg is a rentable building for seminars, company events, rehearsals and concerts, set beside the Schwendisee in Unterwasser. The foundation behind it describes the house as a walkable instrument: the rooms are built to resonate, and two outdoor stages face the lake. Companies, choirs, musicians, associations and private hosts can rent the rooms for their own events.

Seminars and company events

For meetings, the upper floor is the place to start. Raum Iltios measures 93 square meters and has large windows that open onto the central hall. A connecting door links it to Raum Lütispitz, which measures 63 square meters and is described as a breakout room, a lounge during courses, a space for a VIP apéro or a room for a small strategy meeting. Together the two rooms suit a seminar with parallel groups.

The Zentralraum, the central hall, is the largest room and is also used for the spoken word. Panel discussions, symposia and assemblies are listed among its uses, and the venue shows it set up for company events. The rental page names rooms for company events, seminars and further training, and the venue offers group programs and a co-working space with a meeting room in Unterwasser.

Weddings and receptions

The Zentralraum is also suited to festive banquets. The rental page shows the Klangdom at the Resonanzzentrum Peter Roth, a second site of the same organisation, under a wedding heading. Organisers planning a wedding should ask which room fits their guest list.

Rooms and capacities

The site gives room sizes rather than guest numbers. The Zentralraum measures 162 square meters, or 235 with the adjoining Raum Schwendisee, and is 6.82 meters high. It holds a Steinway D-274 concert grand. Raum Schwendisee measures 66 square meters. The Echoraum is a semicircular room of 28 square meters. Raum Schafberg measures 80 square meters, is acoustically separate from the rest of the house, has a fully glazed outer wall facing the Schafberg and the Säntis, and has its own access through the basement. The Stube measures 89 square meters and is used for dining. A control room of 13 square meters serves recording sessions.

All main rooms have built-in audio and power panels with speakers and handheld microphones. A brochure and a rental price list are available as downloads, and the booking request is a form on the site.

Accommodation

The venue does not run bedrooms. It lists accommodation partners in the Toggenburg for guests who stay overnight.

Catering

A kitchen and kiosk next to the Stube serve coffee, tea, soft drinks and local snacks, and a loggia terrace is open in good weather. Stump's Alpenrose is the gastronomy partner and can cater individual events. A Klangbuffet is offered before cultural events.

History and setting

The Klanghaus opened on May 24 and 25, 2025. It is a timber building in which architecture, sound and landscape are designed together, and it was the subject of a book published by Lars Müller Publishers. The setting is the Schwendisee, below the Säntis range.
