“Mountain” is the main theme of this sales office, which is inspired by the geographical background of Chongqing. The pattern of grey marbles on the floor is forming in triangular shape; and there are lots of odd and sharp angles and corners on the feature walls and the irregular shaped reception counters, to demonstrate the concept of “mountain”. In addition, the stairs connecting the floors are designed to be a passage through the cave. Meanwhile, LED lightings are hanged from the ceiling, imitating raining scene in valley and presenting natural feeling, to soften the whole impression.
