P & B Company unveiled its own Eyes Error project. This project is structurally and architecturally unconstrained and is itself the main building block of the project. The main concept of the project was to condemn the judgments of the people towards each other and respect the climate of the northern regions of Iran. This project is located in Chaboksar city, Mazandaran province. This duplex villa with an infrastructure of about four square meters is expected to be exploited by 2020.
