The Circlewood consortium, a collective of architects, engineers, builders and researchers, has designed a modular building concept that will act as the basis for up to 30 schools in Amsterdam. The three-storey plug-and play system, called the HoutKern Bouwmethode, consists of standardised wooden columns and cross-laminated floors connected by recycled steel joints. Components are digitally controlled to decrease assembly times and are built on site with the help of an electric crane. …The base’s load-bearing walls enclose areas that can be used as classrooms, auditoriums and gardens. The walls themselves are made from carbon-absorbing materials and can be used to support indoor climbing and vertical farming.
