Interior Space and Exhibition Design X5 Charity Foundation Office and Exhibition Space by Tai Chen X5 Charity Foundation is a compound interior space that serves as an office and an exhibition area. The first floor holds the work area and a studio for podcast recording and video filming. A hidden lounge and a wine cellar are placed in the basement. An outdoor balcony includes a water sink made of wood and stone. The design repeats the letter X, a sign of multiplying, through lighting and metal fabric set at a sixty degree angle. The X shaped metal runs from the outdoor area to the ceiling and folds into a staircase to the basement. The project renews an old building in Taipei.
