this blog is dedicated to the Bucky Lab from the TU Delft faculty of Architecture. Within the mastercourse we design, develop and at the end build architecture and building construction related prototypes. Its a "get your hands dirty" approach in which the students learn how to translate concepts from sketch into working prototypes. We try to live the spirit of buckminster fuller: what ever you can imagine, you can also build!
