"Good Heavens, Why?": I am trying to visualize the appearance of a library; the room is shaped as an octagon and extends three storeys from the ground floor. On each of the two higher floors there is a projecting hall with a railing: think of a wrap-around arcade or balcony. Each face of the octagon is formed from an arch.
I feel as though this is exactly the sort of structure that one would find in a mall or a hotel, but I haven't found anything that suggests what the interior might look or feel like to a modern viewer, or evokes in me the reaction that I'm trying to evoke in my description.
I can give the architectural dimensions down to an inch, but I can't actually describe the structure I want --I'm trying to get a sense of how open- or closed-in it might feel, how the light would move through the structure.
Any suggestions of buildings I might search, or images that sort of fit the bill?
