Our office

Starting december 2019 our office can be found at the Nieuwelaan 72 in Delft. We occupy the first floor of this beautiful new building. The building is designed and constructed by cepezed, a Delft-based architecture firm. Our office building is an example project displaying concepts of circular economy and circular construction. The building is completely free in how it can be rented out and used. Furthermore, the building is entirely dismountable, which means that its parts can be recycled and reused easily. This makes it possible to tear down this building and easily rebuild it at a different location.
