Yes,Philosophy seems very important to me because when we design a building we will create many types of buildings. One's choice is one of a kind. Everyone's philosophy is different, just like when we design a building for a doctor, we have to design the building according to his philosophy. When we design a building for his photographer, we do it according to his philosophy.Again, when we go to design a religious institution, we have to keep in mind their feelings. For example, when we design Muslim architecture, we have to do it according to their philosophy. Again when we design for people of Hindu or Christian religion we have to think  their philosophy.I think philosophy is very important in conceptual work.And I think more so, if I can understand a man's philosophy, I can meet all his needs.
