Performance space with 360° spatial sound system

Available for
private hire


The Reethaus is a space for radical presence. With its hand-thatched reed roof, monastic cement interiors, in-built 360-degree spatial sound system and an opening in the ceiling that connects the space to the sky, the space was designed for profound encounters—with arts, with ideas and with each other.



Designed by Austrian architect Monika Gogl in homage to ancient temples, caves and other natural voids, the structure brings visitors into a singular aesthetic environment characterized by haptic contrast and deep calm. The roof was hand-thatched by Berlin’s last traditional reed roofer. Under the natural reeds, a retention roof made of lava stone from the Eifel region in western Germany captures and stores rain to feed the landscape throughout the year.


The Reethaus interiors were designed in collaboration with Cédric Etienne, whose Still Room concept aims to create a “sanctuary of silence.” A modular system by Belgian designer Cédric Etienne employs material such as burnt and scented cork, waxed oak and woven tatami to enable a rich variety of gatherings and experiences.

In the inner room, an in-built 360-degree spatial sound system by Wax is programmed in partnership with the pioneering spatial sound collective Monom, based at Funkhaus, just downriver from Flussbad.  Visitors have the opportunity to experience immersive 360°, 16-channel sound for performances, installations and a range of other auditory experiences.

Members library & clubhouse

RESTAURANT & clubhouse

A brasserie-style, all-day restaurant is located on the ground floor of one of the original riverside bath structures dating to Flussbad’s earlier incarnation as a Weimar-era public bathing facility that once welcomed up to 10,000 visitors per day. Focusing on sustainable, vegetable-forward cuisine, the restaurant and terrace bar will offer a rotating menu available for both dine-in and take-out service.

A members’ clubhouse offering all-day dining, the Bootshaus Library on the reconstructed first floor of the original bathhouse structure is a loungey, comfortable workspace during the day and a bar-hangout by night, replete with lush seating, artworks and books. Available for private dining and other small-group bespoke events, the loft-like Tower Studio at the top of the structure will host a revolving schedule of chefs in residence for special 12-seat pop-up dinners facing out over the campus and onto the verdant Spree riverside.



3400 m2

Rooftop terrace

Community space

Set within an original concrete structure that was once an East German customs administration building, the Platte’s reconstructed interiors were designed in collaboration with the Belgian architect and designer Tom van Puyvelde and Augsburg design firm Dreimeta. As the first phase of campus development, the Platte has housed the offices of Slowness for the past three years.

Distressed walls and exposed structures frame the building in a juxtaposition of old and new. The material concept is a mix of poured concrete, darkened metal and understated fixtures in multiple tones of gray and black.
