There is a long history of the architectural model as symbolic offering. The history of the architectural model is typically structured around the presumption that models are first and foremost representational objects and that their primary power is in the communication of intent. A visit to any major alchitectural practice or school of architecture soon reveals a collection of so-called "concept models". The common characteristic of these models is not found in their materiality or in their making, rather it is one of intent and distance. There is a second category of conceptual models which could, more correctly, be described as miniature. Finally, there is a less common category of idea model where the model serves as the architecturalisation of a concept. In these rare examples an idea is modelled for the purpose of explanation or analysis. If then, in the context of archrtectural practice, the working models produced by architects qualify as examples of homo faber-models in the service of work- then perhaps idea and concept models might be considered under the banner homo ludens; the man who plays?
