Regarding our Client’s demands, we developed and proposed a scenario for this project to become an office building that could host high-tech companies with their demanding high standards. We named this type of office space as i-office. Due to the common abundance of bad quality of construction of short-lived buildings that lay their materials to waste, and to a shortage of quality office space, it was decided that this building should become efficient and reproducible. We believe that construction in Iran is the consumption of the country’s excess oil income and the more you save up on oil, the more oil your descendants are going to have. It thus led us to the strategy of prevention of prodigality throughout the different phases of the project ranging from construction to use. At the urban scale, the building aims to maximize its interaction with the urban context and maintain the principles of the cityscape. In other words, losing net space despite the fact that it increases the quality of space, can cause its own problems; to gain added value from such a project would become much more realistic if an architecturally high-quality space could be achieved while making maximal use of the land plot. Traditionally, Tehran’s elegantly crafted office buildings used to portray such a goal. We designed a façade with a dynamic mass that is a border that communicates with the city and uses contemporary craftsmanship thus becoming Tehran’s façade itself. The balconies, as grey spaces on the façade, are spaces of getting connected with the open space for i-office staff to repose and refresh. The office spaces are designed in a flexible manner allowing the staff to define their own way of “being” in place in their workplace. The border between inside and outside, a grey space shrivels: to create a diverse and dynamic space for its users. Other spaces of the building ranging from the roof to parking have been designed as quality spaces maintaining the highest functional standards.
