A workshop in formal composition using machine-based specifications of parametric shape rules is presented. The workshop is structured along two different trajectories: one starting from existing grammars and one starting from scratch, and both in a rising complexity in the specification of the rules and the ways they affect design. Rules, productions and designs in corresponding languages illustrate the findings. A speculation on a new design workflow whereas the designers seamlessly design and test their rules within their design processes is briefly discussed in the end.

We would like to thank the undergraduate and graduate students at the School of Architecture at the College of Design at Georgia Institute of Technology, for their great enthusiasm and hard work during the workshops on shape grammars and their implementation in GRAPE.
