Utilization of these geometric properties in an actual design
application yielded a number of valuable insights. The practice
of the process revealed its basic pragmatic virtues in terms of
directly setting out the design upon the site using datums and
proceeding to investigate alternative commensurate subdivisions
of the datum frame. This directness of application extends to
the actual construction process where some of the geometrical
design processes are also done at full scale. Such a practice
recalls that of classical times where a courtyard floor or
building templum is used as a layout table and palimpsest of the
construction process of the building. The directness of this
application provides a ready feedback and verification of the
design in the field. It can also provide the opportunity for
unforseen minor adjustments in the original design. In doing so,
the process allows for improving the fit between the original
design intention and its final implementation.
A new strategy for studying the properties and processes of
ancient geometrical architectural design occurred in 1988 with
the design and construction of the Watts house in Manhattan,
Kansas, USA. The author, together with his wife and colleague
Carol Martin Watts, had been studying the geometric ordering of
classical Roman architecture for nearly a decade and had learned
many geometrical design properties previously unknown to us and
today's architectural profession. We realized that while much
important knowledge can be learned from the analysis of historic
structures, other important lessons could only be learned through
applying these geometric systems to the process of a new design.
After all, these historic geometric patterns were used as part
of a design and construction process at the site of ancient
buildings. The Watts house therefore became an important
extension of our ongoing research of geometric design processes
in architectural design.
