developing architectural concept through internal logic of form: a case of cardboard houses

In course of the years 1968-1978, several houses has been designed and numbered chronologically by eisenman under the title of cardboard houses. these houses all can be counted as a pure intellectual approach to abstract formalism in architecture. that is, total disregard of functional, programmatic or any other social conventions on the side of focusing on developing architectural concept through internal logic of form. although the cardboard houses as a didactic heuristic design approach has been addressed in some studies, still there is an essential call for more close examination of these houses regarding the manner by which internal logic of form operates as driver agent of architectural concept through design process. thus, the main objective of this paper as a qualitative documentary sturdy is close examination of the houses ii, iii, iv, vi and x, namely the most instructive ones in the series with focus on the way architectural concepts in these works has been derived from internal logic of form. the demanded data has been collected by literature survey, mostly texts written by architect himself, and then analyzed through analytic-descriptive method. the findings illustrated that cardboard houses can be counted as a progressive project wherein each of the houses was a unique exercise and different investigation of from evolution which is more tangled than its precursors. in each case certain transformational operations based on internal logic of form has been occupied for developing architectural concept.
