CONCEPT : EXPOSING THE SPIRIT OF THE SITE
I think that the weekend home in the mountain in addition to the weekday home in the city is intended to provide variation to the lives of the users. The "inwardness" as well as "non-physical" nature of our relationship to our surrounding in the city tends to leave us "shielded" from the nature as well as our physical-self. I see that the weekend home in the mountain serves not necessary to take us "away" from the city life (because city life itself can also be wonderful and stimulating in one way) but to "expose" us to the "missing components" that would give all of us a more "balanced" existence.

Therefore, the house should "expose" the users to the positive sides of the surrounding (the mountainous context, a view of the Great Wall, the clear sky full of stars, good air, various viewpoints) but at the same time has to be able to "shield" the users from the natural elements that might be too harsh for human being to take (the most fundamental idea of shelter). The idea is concentrating on creating strong relationship between the indoor / outdoor space(s) in terms of terraces and courts.
