The pattern used to create the façade is based on a simple geometrical principle, first practiced on a A4 paper. The paper was cut along several parallel lines. Consequently the strips of paper were bended on their longitudinal axis with a variety of angles. Anti-oxidation copper sheets were used to create the main form of the façade. The color of copper could compensate the gray and smoggy atmosphere of the Iranian big cities. Aluminum sheets were used to reinforce the copper sheets and steel profiles used as sub-structure for connecting the façade to the building. Behind the copper façade there are burglarproof windows and a rollup steel curtain as the last protection device.
