With the above three requirements, there were two questions to be answered within the design. First was to ask; How can we provide a system with much flexibility that would respond positively to the future changes (in regards to floor to area ratio) that might occur? And, How can this system coexist with the client request of new typology of an office building and the application into the urban environment? In response to these questions and request, the architects came to a conclusion of facade structural net system.
