Three examples such as Bundang Exhibition House, Paju bookcity, and Heiry Art Valley, will be analyzed in terms of the development of design guidelines and the site survey of built environments. In doing so, an architectural design element named as "facade-poche" will be introduced. A facade-poche designated the surface and space around the building facade. It would be overhead weather protection in general. Three examples of collective design will be analyzed with the element of facade-poche.
