Proposal 1
Add one more entrance at the right so that public and private can have separated entrances. And design an open place in the middle where everyone could enjoy the wonderful nature view and this space could be a functional transit place.
We put foldable furniture in the middle of lecture space. Once there is no student, all desks and chairs could be storaged in the movable circle space and this curved wall could be used as a bench.
Proposal 2
Use curved wall to push and pull spaces into different function rooms. No doors or dividers are needed. And curved wall generate interesting experience for users. All kinds of space are wrapped by several simple walls which could be turned into shelves, covered by local cloths products and local hand-made metal artifacts.
