The theory of value is at the root of goodness. It is the intrinsic value that determines what is good, how good it is, and morally. Anthropocentric philosophy has given man the right to rule nature by saying that everything is for man, living and non-living things other than human have no intrinsic value. Humans have destroyed nature. Today, the movements for the environment have fed capitalism under the mask of production, consumption and technology that protects the nature, and the solutions are for that day, for that problem and, in fact, for people.


More than 50 percent of the human population now lives in cities, and this number is expected to rise to 66 percent by 2050. Biodiversity and native species are constantly disappearing. The remaining species also have to seek new resources. In many metropolitan cities of the world, animals began to live in cities. In time, they will invade the cities and gain access to the resources to which they are entitled.

With the areas opened to urbanization in Istanbul, the natural life has almost disappeared. Green spaces in the city are now very few. The scarcity of green spaces mobilized the activists. Rewilding action has been initiated for resilient cities. They aimed to revitalize the small green spaces that exist in the city center and spread them all over the city. They were sights that the public longed to see.

Activists decided to green the Bosphorus Bridge to call more people to action. By rewilding the soil surface at the feet of the Bosphorus Bridge, they increased the existing greenery with vertical gardens. The vertical garden grew uncontrollably in a short time, forming a green net between the foot of the bridge and the Nakkaştepe grove. The puddles formed by this green web were the harbinger of a new habitat. The traffic flow, which was stopped for a long time for the greenery at the end of the bridge and the bridge maintenance, caused a few animals in the nakkaştepe grove to overflow. This new formation on the bridge has been so good for the people that many people from the public showed a desire to be here. Realizing that with the increase of volunteers, social consensus began to emerge, the activists organized to close the bridge to traffic and spread the habitat to the bridge with the support of the people. However, since the habitat to be left on its own on the bridge could not continue with limited resources in a limited area, it needed resources for the continuity of life. At this point, the social consensus he formed with the beginning of the habitat made an effort by the activists to take a place under the bridge for the protection and glorification of the habitat. With the call to bring wildlife back to the cities, the activists, now backed by the public, have established an infrastructure network that maintains the knowledge and social power for the sustainability of the habitat here in the middle of the city, together with the city.

In the urban context, Istanbul is the area that consumes the most resources in our country today, and is still the area where the green areas are slaughtered, the natural life is not respected and we feel this universal problem the most. With the call to bring wildlife to the city, I settled under the habitat and created an infrastructure that supports the habitat, based on the attitude that we should work for the sustainability of the habitat. In the future scenario of the habitat, it completely occupies the bridge, giving the city the awareness that wildlife has settled and people have to work for the continuity of the habitat. Starting from the stage where the green area begins to spread, the infrastructure continues along the entire bridge and exits are provided at the western bridge piers.


Infrastructure consists of spaces that build community strength, provide life support and technical support, and a gateway that enhances biodiversity. The north has indoor spaces, while the south has green structures to increase biodiversity and return local species. While the green structure is sometimes populated indoors as an open space, indoors the green structure is populated with the nursery space. There are 3 different circulations in the building as closed, open and catwalk. While the catwalk allows to experience the green passage, it sometimes extends to the closed areas. There are places to maintain social reconciliation with nurseries, seed drying and germination, plant and animal care workshops, presentation, exhibitions, libraries and meeting areas. It includes seed development, resistant seed research, plant care and animal care units, and spaces that will provide vital support for both the habitat and the biodiversity gateway. There are sea water distillation system and water tanks, technical maintenance, control points and technical units and technical support areas that provide access to the habitat with tube circulation. The technical floor is accessed by a different staircase and elevator. Access between technical floors is through a closed tube, which provides access to the habitat for habitat needs and maintenance. There are also distillation tanks and water pipes to meet the needs of the habitat and biodiversity gateway.
