Interior Space and Exhibition Design Formula Store by Hsu Ti-Pin This chain store coffee brand is housed in an independent building with a height of 6.5m, and features large areas of windows on each side for ample lighting. The simplistic yet stylish black, grey and white design quickly made it a popular check-in spot once it was completed. The interior is adorned with triangular 3D geometric shapes, evoking the image of ice drip coffee which the cafe specializes in.
