The article problematizes the concept of Contemporaneity to open up a discussion on architectural creation through design. It asserts that to interpret and to problematize the changing dynamics of architectural creation in actual conditions, the Contemporaneity opens a new field of comprehension. Accordingly, the article endeavours to conceptualize the concept of Contemporaneity in terms of its temporal, spatial and informational qualities in context of architecture with reference to the related discussions in philosophy and art. Far from fitting Contemporaneity into a particular definition, the article uncovers the possibilities that the Contemporaneity provides to experiment with architecture through design thanks to its experimental nature. It interprets the Contemporaneity as contextual being that provides a running room for experimenting architecture. In this perspective, it proposes to reposition architectural creation in a running room opening to Contemporaneity. Accordingly, the realization of architectural creation in the design space spread over such a running room is brought forward and the spatio-temporal informational configuration of design space as a basic architectural creation field is opened to discussion.
