Among the searches about Tehran's urban potential, the issue of the subway entrance became very important to us, and we started studies and needs assessment about it. Considering that in these years, the subway space in Iran has been one of the most important spaces for starting an important and influential social confrontation between the people and the government, this question was raised for us. Why were these spaces defined without ideas and without regard to spatial quality, connection with the city and the quality of life in the city? The former state of this site was full of heterogeneous elements and urban facilities and We tried to come up with a new definition for these entries by adding a space to them.

The project is at the intersection with this main skeleton of Tehran city and one of the important streets with cultural monuments of the brilliant era of urban planning and we came to the conclusion that this intersection needs a landmark building that has a dialogue with the former urban landmarks. In one hand somehow try to use underground forms as a base form for the space above the subway On the other hands this form exists in the historical architecture of Iran and also in the architecture of the urban layer of old Tehran in landmark buildings and creates dialogue with these historical landmarks in the layer of the city.

We tried different types of the combination of this vault form and for economic reasons, the construction strategy of the project was considered in such a way that the geometry of the structure becomes the final form. Just by covering it, we can implement the final product with the lowest cost. Brick material has played an important role in the formation of the city of Tehran. This material is very suitable for the climate and resistant to the pollution of Tehran and maintains its durability over time.

With this choice, we tried to activate the forgotten and half-worked workshops around Tehran. In this project, 300,000 hand-made bricks from soil have been used. This project was an attempt to redefine subway entrances in Tehran and define these entrances as a free and definable platform by users for urban events and define points of the city as connection points for Tehran's pedestrian-oriented city plan. This space is accessible from all roads and creates an urban node that evokes a labyrinth.
