The Iran-Switzerland Chamber of Commerce in Nejatollahy street, located in a central area of Tehran, required a renovation work. The main idea was to create an open fresh space where the Swiss companies represented in Iran could feel a sense of quite, positive energy but at the same time familiarity. Ahmadi Studio decided to totally change the shape of the area. The final result is a fresh and colourful space with a big and bright working area easily transformable according to needs. A sober and reserved meeting room and the offices and spaces required for the normal administration of the Chamber. All environments have a fresh touch of Switzerland in the colours used or in the details in the ceiling.
