After the site tour, I got two options in my mind.Finally,I chose the second one.
The reasons of my choice are based on the following points.
-Not close to student residential
-Not blocking the views of other buildings
-Conserving the environment (Not chopping down trees)
-Not blocking the circulation (the yellow path above)
-make better use of idle space
-possible around Square House
The disadvantage of site 1:
Sitting on a higher lawn,although it is not occupied so often,it create a peaceful atmosphere.It is also like a memorial lawn.
It is hard to design a building in such a sloped terrain.
It will block the north side of the Square House,which enjoys most of the sunlight, although I want to make better use of the north facade of square house, for example,the bottom part can link better to the lawn nearby.
Therefore,I chose the option 2,which
Will not block any view of building, more space between buildings, so can receive good deal of natural sunlight.
Sitting on a flat ground
Making good use of idle space ( the grass land outside the entrance of Square House)
(I plotted two main trees on two sides of the chosen site.)
