Greek architects 314 Architecture Studio imagined an eyewear store with a courtyard playing with anamorphosis and optical illusions. From a far spot, the viewer has the impression to see a floating terrace with a closed cubic shape. In reality, the space is totally opened and what creates the illusion is the black lines’ marks and the white painted walls in a square shape. The shop is named C_29 / Optimist and you can visit the courtyard by going to Chalkida, on the Euboea island.
