Sanaa’s housing projects, both finished (House A, S House, House in a Plum Grove, Small House and Moriyama House), and unfinished projects (Flower House, Garden & House, Seijo Apartments, Ichikawa Apartments, House in China and Eda Apartments). SANAA's architecture embraces complexities within deceptively simple appearances. It has many elements that are impossible to understand unless actually “experienced”. In contrast with modern architecture, SANAA has many aspects that cannot be revealed in “representative” media such as plans, models, and photographs. The “representations” of their architectural works incorporate ambiguity and chronological elements. This characteristic makes Sanaa one of the most innovative offices in the current architectural panorama.

For their intervention, Sanaa decided to use acrylic to make transparent curtains. They imagined an installation design that left the existing space of Barcelona Pavilion undisturbed.

The acrylic curtains are standing freely on the floor and shaped in a calm spiral. The curtain softly encompasses the space within the pavilion and creates a new atmosphere. The view through the acrylic will be something different from the original with soft reflections slightly distorting the pavilion.
