Abstract
Generally, theories of modernism urban architecture in the first half of $20^{th}$ century are known to be developed among debates in CIAM. At the time of formation of CIAM in 1928, one of the important concepts among those times was the standardization. CIAM had focused on the relation between architecture and general economy system and linked economic efficiency into the method of building production, declaring this way to be the universal modern architecture. However, the idea of Berlage who had already performed various collective housing and urban planning projects on the basis of the standardization was distinguishable form what CIAM had pursued on. Berlage's idea of standardization in terms of urban architecture was just like a tool, which embodies the new city culture and it was a part of his plenty of other urban architectural ideologies. In Berlage's idea of urban architecture, city structure must be consisted with human behavior-oriented factors such as housing, not implementing strategy of reductionism or simplicity, which CIAM had proposed. The point is, although Berlage signed La Sarraz declare of 1928 nominally, CIAM's notions did not meet Berlage's lofty goal, and CIAM's rather iconoclastic way of proclaiming La Sarraz declare was clearly contradicted to theoretical position that Berlage indicated.
