“The path from the digital drawing board to an actual building has challenged both scientists and experts from industry,” said Empa CEO Gian-Luca Bona in the joint press release. “Through a constructive dialogue, something truly visionary can now be put into practice; hopefully, it will soon be used broadly in the construction industry.”

The building is located in a bit of an unusual spot: perched atop the NEST (Next Evolution in Sustainable Tech) building as an experiment in building and construction. The NEST is a three-floor central module that engineers can “dock” building modules onto, much like attaching different pieces to a LEGO brick. Owned by building companies Empa and Eawag, the building has hosted multiple building experiments over the years.

The latest one, docked on the building’s third-floor platform, is a three-story house created by robots and 3D printers, with “smart home” tech inside. The top two floors are largely made of timber, put in…
