1、,Case Study Project Exeter Library 4243323,Exeter Library Louis Kahn,“Inspiration is the feeling of beginning as the threshold where Silence and Light meet. Silence, the unmeasurable, desire to be, desire to express, the source of new need, meets Light, the measurable, giver of all presence, by will

2、, by law, the measure of things already made, as a threshold which is inspiration, the sanctuary of art, the Treasury of Shadow.” “No space is really an architecture unless it has natural light.” “Evenaroom which must be darkneeds at least a crack of light to know howdarkit is.” “A great building, i

3、n my opinion, must begin with the unmeasurable, go through measurable means when it is being designed, and in the end must be unmeasurable.” “I see the library as a place where the librarian can lay out the books, open especially to selected pages to seduce the readers. There should be a place with
