A chartreuse form attached to the roof of a Rotterdam warehouse, the Parasite project is a prototype for a new form of urban housing – urban infill designed to explore the relationship between sustainability and prefabrication. So just how is this project sustainable? The prefabricated panels, both load-bearing and insulating, are manufactured from waste wood and can be assembled in only four days. It is also designed to take advatage of the existing building’s water and heating systems. Many of the other works in the Green House include technologically advanced environmental systems, but with the P.A.R.A.S.I.T.E. PROJECT we are presented with a green house that is both simple and thoughtfully constructed.
