About the Exhibition
TOTO GALLERY・MA is pleased to present “Water Works - in the Flow of Making” by raumlaborberlin, a Berlin-based architect and artist collective.
raumlabor, or “space laboratory” in German, has continued to create flexible, open-ended spaces for interaction in highly constrained modern cities through participatory, hands-on approaches such as building communal baths from makeshift materials for everyone to enjoy and setting up community kitchens where people can cook and engage in conversation. Their activities have been highly acclaimed, particularly in Europe, earning numerous awards in architecture, design, and theater, including the Golden Lion at the 2021 International Architecture Exhibition—La Biennale di Venezia — for their representative work “Floating University.”
This time, they will explore the potential of “water”—a theme they have been working on for many years—in Japan. Ahead of the exhibition, they held a workshop with students from the Shibaura Institute of Technology School of Architecture. The workshop involved combining inflatable dunnage bags (transportation cushioning material) with bamboo they encountered in Japan, untangling and navigating various regulations governing maritime use, and staging a performance on the deck of a barge—an unprecedented form of intervention in Tokyo Bay. By intentionally avoiding architectural frameworks and directly connecting the body to the city, this initiative not only fosters dialogue among people but also creates ripples that unlock new possibilities for maritime use, projecting alternative visions for cities. Furthermore, as indicated by the exhibition’s subtitle, “in the Flow of Making,” the materials used in the workshops are repurposed in new forms. We invite you to our gallery to experience firsthand the world of raumlabor—a collective that continues to present alternative visions of society—as you immerse yourself in their playful, experimental architectural practice, encompassing workshop documentation, studies on water circulation, and visions for waterfront environments.
Message from the Exhibitor
Water Works – in the Flow of Making
At a place called "Bay of Rummelsburg” of the river Spree close to the Berlin city center, around 150 people, who can no longer afford to pay the rent, live on old rusty barges and DIY houseboats. Living on a boat has a tradition in many places. Here in Berlin there is no law that requires technical checkup for water vehicles and anchoring in the bay is boat-parking-fee free. The only rule is that one person always has to stay to secure the boat. To go out and move around freely they towed the boats together as clusters, so just one person is required to be on each floating island. Isn’t this a brilliant idea? Especially for overcrowded cities, with hyperventilating housing markets and delirious regulations protecting landowners, not tenants! On this rare occasion of a frozen river, the people living in the expensive new apartment blocks around the bay and the squatters of the liquid public space start to mingle: middle class kids and parents skating in the sun between the boathouses, boat families going shopping with a wheelbarrow across the ice. What a wonderful sight! While we spun our pirouettes around these charmingly frozen though partly precarious lifeforms, we thought we should bring ideas like this to Japan.
In Japan, a spectacular urban plan for the development of Tokyo caused a sensation 66 years ago. Kenzo Tange commented his "Plan for Tokyo 1960": On the intricate levels of artificial ground it would be possible to build a city free from restraints imposed by land and to produce new space values as well as new hopes (Shinkenchiku, March, 1961). It proclaimed that many of the megacity’s problems could be solved with a small shift of perspective. No more chaos and unbridled sprawl, no untamed land consumption by the modification of the very nature of the city. The simple shift of perspective was viewing the bay as part of the city. Despite all criticism we can have about his partly dystopian vision today, we have to respect Tange for his plea and struggle for the imagination of a better city for everyone.
We resume the discussion around the urban leap into the water and transforming the city into an open dynamic harbour. As a first step we row into the Tokyo bay to explore the potentials of urban life on water with a group of SIT students. With our architecture of active urban praxis we invite everyone to never stop rethinking. At the gallery will present this joint adventure along with some of our previous water related works in an active space for learning and unlearning.
Water Works is an exhibition enjoyable for people of all age groups. Kids, bring your parents!
About the Exhibitor
raumlaborberlin is a collective working in the uncertainty of the urban environment. As architects, artists, performers, inventors or curators, the nine members have tapped into various spaces of action. The group was established in 1999 from a common understanding of space as a product of social interaction and a mutual interest in urban practice. raumlabor’s working method is situative, embodied and action-oriented, with a focus on the collaborative production of space as an open and unbiased process.
They have been awarded many prizes such as the Schelling Prize for innovation in Architecture (2004), the Swedish Architecture Award (2015), the Roland Prize for Art in Public Space (2021), the Golden Lion at the Biennale Architettura in Venice (2021), the Opus Prize for scenography (2022), the DAM Architectural Book Award (2024), and the Tabori Prize 2026 (Federal German Theatre Award).
Workshop Report
Ahead of the exhibition, members of raumlabor visited Japan to conduct a two-week workshop as part of their Water Works project. Together with students from the Shibaura Institute of Technology School of Architecture, whose campus overlooks the Toyosu Canal in Tokyo Bay, they completed a one-day performance titled “Amembo Maru.”
