In a groundbreaking example of circular design, the Netherlands-based Triodos Bank has constructed an
office building that can be fully disassembled and reused at the end of its life. The building, designed by
Dutch firm Rau Architects, was constructed using an astonishing 165,312 screws, allowing for easy
dismantling and repurposing of its components.
The primarily wooden structure, with towers ranging from two to five stories, stands in stark contrast to
traditional steel and concrete buildings that are welded together and are difficult to disassemble.
Beyond its innovative use of screws, the building boasts several other sustainable features. The wood used
in construction is carbon neutral, and the design maximizes natural daylight to reduce the need for artificial
lighting. The building’s shape was carefully considered to minimize its impact on local wildlife, and the
landscaping includes a pond for animals to drink from.
The office also incorporates renewable energy technologies, such as solar panels and geothermal heating
and cooling, while encouraging eco-friendly commuting with bike facilities and proximity to public
transportation.
Perhaps most unique is the building’s status as the first “temporary materials bank.” All materials used in the
design are logged on a public platform called “Madaster,” which tracks materials in the built environment to
eliminate waste. Each component, from wooden beams to glass panels, has a “materials passport” detailing
its specifications and origins.
At Tsamouris, we recognize the importance of innovative fastening solutions in enabling circular design and
sustainable construction.
