Located in the Contemporary Art Center of Beijing, TianAn Time & Art Space is a new quadrangle courtyard built in the traditional architectural pattern, to which the designers find no definite historical clue, and find unsatisfactory to meet functional demands for art space. The modification raises the outdoor ground to the same level with the indoor floor, and the traditional black brick floor is used both interior and exterior to form a uniform flat display space. Tedious traditional forms and signs are discarded meanwhile modern simple wall body is adopted to partition the space; roofs, doors and windows are composed of industrially-processed metal frames to embody the idea and attitude of self-orientation idea on time dimension.
