Digital technologies extend, displace or substitute entirely new elements into what has been observed so far in the traditional modes of conception, representation and communication of design. This paper examines various characteristics of digital media and representations, their impacts -constraining and liberating- on modes of conception in design, and possible shifts in design expressions and ways of designing. While much effort invested in research to date has relied upon architecture as conceived, taught and communicated in traditional modes, the use of digital technologies changes those very premises. The import of such characterisation for design computation research is to highlight emerging agendas for future investigation.
