As previously mentioned, the design and preparation of the functional programming for the plaza in front of Tehran's first metro station, which serves as the western gateway to the metro (Sadeghieh Metro Plaza), were assigned to our studio.
Initially, we examined the site's challenges, which are:
1. The high density of users in the metro plaza and intense pedestrian circulation from nearby neighborhoods toward Sadeghiyeh Metro Station.
2. The significant presence of street vendors along the paths leading to the station, which required a solution to regulate and organize their activities.
3. The disconnection between the metro façade and the central plaza, which hindered functionality.
4. Open urban spaces with a high density of people are often venues for hosting street events during specific times of the year, such as temporary Nowruz bazaars, street musicians’ performances, religious ceremonies, and ... Unfortunately, due to the significant disarray, lack of control over pedestrian and vehicular circulation, and general disorder in this site, no dedicated space has been allocated for such activities, despite a pressing need for it.
Our studio encountered multiple challenges on this site, requiring a comprehensive design and urban planning to address all the issues. We began by studying pedestrian and vehicular circulation diagrams to identify appropriate pathways. Essential functions were also analyzed, leading to the following design components:
1. Spaces for organizing street vendors.
2. Short-term seating areas for metro passengers.
3. Parking and landing zones for taxis.
4. An open-air amphitheater for events, performances, and street musicians, serving as a waiting area for passengers.
5. Green spaces, preserving pedestrian pathways.
6. Slope-integrated features to harmonize the edge shops with the plaza.
By identifying appropriate functions and paths while avoiding new construction, the goal was to create a suitable plaza for the entrance to Tehran’s first metro station. The design required a simple yet coherent geometric concept that could align all the desired functions along the main pathways, providing solutions for the complex challenges as if they had never existed.
The concept revolved around the repetition of a circle, centered on the intersection of pedestrian and vehicular pathways.. The circular offsets extended toward the metro entrance, rising and lowering to form various features. In some areas, they rose to create seating platforms; in others, they shaped planters, guided pathways, or elevated seating tiers for the western amphitheater. In front of the metro, the tiers "stepped down," opening the central plaza for pedestrian flow and providing platforms for vendors.
By harmonizing essential functions along clearly defined pathways and avoiding intrusive construction, the design provided elegant solutions to the site's complexities. The resulting plaza not only addressed the challenges but also redefined the entrance to Tehran's first metro station as a vibrant urban space, seamlessly blending utility, aesthetics, and cultural significance.
