AIQ19XPT The aim of the project is to create an aggregation centre around a urban green hub. A large green urban area where people can carry out multiple activities related to everyday life, leisure and contact with nature, in full respect of the cultural identity of the places. The current area is a mix of urban functions. Religion, commerce, tourism, leisure and other activities that are intertwined in a site that is currently lacking its own architectural style and cultural identity. At the moment, the only appreciable element is the large garden area, which is also the driving element of this part of Istanbul. A great resource in terms of environmental sustainability and urban ecology. In fact, in our project, greenery will be the driving force towards a high quality of urban life. The whole project area will be transformed into a large pedestrian area. The traffic flows will be interrupted through the construction of new underground roads for cars, buses and all motor vehicles. These will connect to an underground level located at an altitude of 15 meters lower than the current area of grounds. The project area thus freed, will become an urban aggregation hub in full respect of environmental sustainability and cultural integrity. The project envisages a radical intervention to empty the current hill on which the park of Piazza Taksim currently stands. The plants will be carefully explanted and temporarily planted at another site to be subsequently reused within the new urban park that will be configured. For this reason, in the executive project, an accurate time schedule of the explanting operations will be drawn up so that the plants can suffer slight trauma in the best climatic conditions. The hill will be emptied up to an altitude of - 20.00 m from the current area of the square and up to intercept the existing underground services axis. In its place there will be a building on four elevations, two of which are underground, one semi-underground and the last in elevation, located at the altitude of the Mete road. The new park will rise on the roof of this building and will have an extension of about 26,000.00 square meters. The building, which will have all the bio-architectural construction features of a passively and energetically autonomous building, will be completed by a small service block, located to the north / west (with a surface of 2,400.00 square meters) with a threeterrace construction system and gardens hanging, and a large photovoltaic pergola located to the south / east, of the surface of 8,000.00 square metersv, which, in addition to forming a large shaded area in front of the mosque, will have the function of producing about 800 Kw / h of solar energy. This will make the entire area self sufficient from an energy point of view. However, the light will continue to filter beneath it, by the use of the transparent photovoltaic panels. The intervention will be completed by the construction, on the entire perimeter of the project area, of a steel porch, with textile tensile structures with shading function, which in addition to evening the fronts of the large square will constitute a long compact corridor of vertical greenery, to be achieved through the use of local plant essences grown with hydroponic techniques. A long green front that will develop for a length of m. 900.00, interrupted only in correspondence with the streets affluent to the square, for a height ranging from 6.00 to 8.00 m and for an area of approximately 12,500.00 m2. The red steel structure, as articulated, simulates the swaying of the stems of poppy flowers cradled in the fields by the morning breeze. The project also involves the rearrangement of the north-eastern area of Taksim square, which is currently at the exclusive service of the Ataturk library, which will be integrated through a set of works that will make the intervention homogeneous and architecturally identifiable. This area, as well as systems of squares and organized greenery, will be made attractive to the younger generations thanks to services dedicated to them: water games, skate track, cycle paths, playgrounds, caves for outdoor performances. A characterizing element of the project will also be the presence of different sources and ponds, in memory of the fact that originally Taksim Square was the point where the main water lines of the north of Istanbul were collected and from there they branched out into other parts of the city (hence the name). In this way, numerous bodies of water and rivers will bring to mind the original function of places. The HUB The main building, with a plan size of approximately 162.00 x 162.00 m, will be arranged on four levels and, given its dimensions, will be vertically perforated by a steel and glass cone, with a base diameter of approximately 40.00 m.

project report
This will allow the penetration of natural light up to the lowest level, placed at an altitude - 20.00 m. from the park on the roof. A shielding system consisting of wooden slats, to protect the intense sunlight, reminiscing the movement of the skirts of the dervish dancers, will be placed to cover the steel and glass structure. The cone, in addition to relating vertically with the mosque in front, will also be a pedestrian link between the different levels thanks to a double system of helical ramps that will allow it to reach its top, placed at a share of + 10.00 compared to the Taksim Park , and which will constitute a point of view and observation on the whole new urban system. The -2 floor, placed at the altitude of m. 62.00 s.l.m., will host all the services necessary for the decongestion of urban traffic and will be accessible through the implementation of the underground road network, already present in the area. This area will house: multi-storey car parks, the bus station (both urban and tourist), interconnecting services to the metro network, as well as services such as shops, information points and refreshment points. In this level there will also be a garage exclusively dedicated to police services. The -1 floor, placed at the altitude of m. 66.00 s.l.m., is actually a space complementary to the one described above. In fact, further services will place in this area, such as: multipurpose rooms (for conferences, screenings, temporary exhibitions, cultural events, company meetings), other refreshment points and a plan dedicated to temporary police housing. A system of pedestrian bridges, equipped with treadmills, will connect this level to the car park system. The 0 floor, placed at the altitude of m. 71.00 s.l.m., is the floor in direct contact with the pedestrian area of Piazza Taksim. This floor area will be mainly consist of an indoor market. Inside there will be steel and glass boxes, arranged on a planimetric design that reminds us of the geometric motifs of the classic designs of Turkish ceramics, which alternate with organized green systems. Part of this plan is reserved for an auditorium where musical or theatrical events can be held. The plan will be completed by the inclusion of necessary services, such as: warehouses, toilets, refreshment points, administrative offices, police offices and more. THE TAKSIM PARK The project intends to expand the green system already present in the area. The trees, which will be planted before the gutting of the area, will be replanted and integrated with other essences, respecting the native vegetation. On the coverage of the Hub, located at an altitude of 82.00 m. s.l.m., an organized garden will develop around the cone. A system of green dunes, inside which large trees will be available, will alternate with traffic, pedestrian and bicycle systems, paved with natural materials and which will guarantee soil permeability. In this way, rainwater can be collected and reused for irrigation. This will increase energy savings and consequently environmental well-being. Other green areas will alternate with parking spaces and pedestrian roads. At the end of the intervention, the green areas will have a surface much implemented compared to the current one and will have an overall extension of approximately 55,000.00 square meters. THE ATATURK LIBRARY The areas of this important cultural attraction will be reconnected to the urban system of Piazza Taksim through a pedestrian traffic system that will improve, without distorting, the orography of the hill which is also located in a depressed area compared to the area of the main square. An oval square will surround the building that houses the library which will be reconnected to the other squares through pedestrian walkways and cycle paths. Green areas will also be implemented and rearranged in this part of the city in order to maximize the environmental quality of the area. The project also foresees the creation of stimulating sites for the new generations through the construction of skate tracks and other recreational areas.
