As the Atlantic Cities best describes, “Leave it to Japan to turn one of the dirtiest and noisiest processes of the urban lifecycle – the demolition of highrises – into a neat, quiet and almost cute affair.”
Japanese construction company Taisei Corporation has discovered a new, more efficient way to disassemble, rather than demolish, a tall building over 100 meters. The process, known as Taisei’s Ecological Reproduction System or Tecorep, begins by transforming the structure’s top floors into an enclosed “cap”, which is then supported by temporary columns and powerful jacks. As demolition workers begin to disassemble the building from within, they use interior cranes to lower materials. After dismantling an entire floor, the jacks quietly lower the “cap” and the process is repeated.
“It’s kind of like having a disassembly factory on top of the building and putting a big hat there, and then the building shrinks,” says one Taisei engineer, according to this report in the Japan Times.

This minimalist elementary school, located in Kumamoto and designed by Japanese architects Kazuhiro Kojima and Kazuko Akamatsu (CAt), is designed to seamlessly connect the indoor and outdoor space. Within the building, individual classrooms and spaces are loosely formed by L-shaped walls that feature foldable doors and flexible components. An abundance of courtyards and airy walkways are just some of the highlights, along with a wood deck activity space found on top of the roof.
