Gramazio and Kohler rst demonstrated an architectural application for industrial robots in their project The Programmed Wall, utilising the repeatability and accuracy of the motions of a robotic arm to automate the human bricklayer and introduce subtle differences in the patterns of laid bricks. As has been noted by Neil Leach such effects would not be impossible to produce by a skilled human labourer but would require prohibitively excessive time and drawn documentation.    However, many assembly processes that rely on an ability to perceive the working environment, require collaboration, combine additive and subtractive fabrication or use volatile or delicate materials remain beyond the capability of industrial robots despite being relatively intuitive for human builders. This workshop examines how mixed reality technology may extend human craftsmanship and enable the construction of complex and differentiated assemblages by replacing drawn documentation with 1:1 models overlaid on the fabrication environment.

The Microsoft Hololens headset is capable of locating itself in space and accurately positioning digital models that can be shared with multiple collaborators over Wi . We have developed software that will be shared with workshop participants enabling them to stream digital models from Rhino and Grasshopper to the Hololens in real time.
By visualising a holographic representation of the completed design model within the fabrication environment, new assembly methodologies are possible that do not rely on ground-up construction (as with brickwork or 3d printing) but instead enable ad hoc and adaptive procedures. For instance, a single structure may be constructed by several teams simultaneously by referencing a single, shared digital hologram. Unanticipated events (such as failure or complex material behaviour) can be responded to during fabrication by developing new fabrication strategies or making revisions to the streamed digital model. Dynamic structures can be built without the need for sophisticated simulation of material behaviour, enabling far more complex formal results to be continuously negotiated and designed during their making. 

The format of the workshop will consist of an introductory lecture followed by a day long tutorial introducing and sharing the hardware and software utilised by the workshop. The workshop will invite participants to use shared software to design and construct the world’s rst holographically assembled architectural prototypes, the design of which will be partially resolved using prepared generative models and partially a product of collaborative negotiation by fabrication teams. The outcomes of the workshop will be disseminated online and in the form of an exhibition, installation and discussion session.
