Interesting...
I like the idea of the enclosed courtyards in the second idea but I like the first better overall, especially with all the windows and green space there. Right now classes in Robinson are miserable affairs and feel hermetically sealed off from the outside world, so either design would be an improvement.
I also think that it makes a lot more sense to start building vertically on the developed land we have in order to have enough room to grow without cutting down the remaining trees we have. Having slightly more open space won't hurt, either.
