This thesis focuses on the case of the former military base Kodra in Thessaloniki, its redevelopment targets to transform into an urban park with innovative recreational and training facilities. At a short distance from the city center, Kodra became over time the most characteristic part of the municipality of Kalamaria. The conditions that people have to deal with when living in urban environments has shifted significantly. At the same time however, despite all the changes in the way of living, the need for joy and relaxation remains as a fundamental human need, maybe even stronger than before. The proposal for the transformation of the ex-military camp Kodra into a park identifies that need as a real, existing condition and tries to create a park that aims at the creation of spaces and events that will be able to provide joy to the residents of Kalamaria and the surrounding areas, through a dense green condition within people can get lost. The park is understood as a place of dense vegetation, seemingly unorganized, that in points, every now and then is disrupted by larger or smaller open spaces, creating internal courtyards hidden within the trees. As the years pass by and the trees grow larger the illusion of the ‘woods’ will intensify. The aim is that someone inside this ‘woods’ could be totally isolated from the urban environment which is actually just a few meters away.
