The diploma thesis focuses on the expansion of the city planning in the area of the old quarries in Tourkovounia.
The mountain range of Tourkovounia is situated between four municipalities of Athens, which it unites and separates at the same time. Due to the pressure admitted to the area from the expansion of the urban fabric, Tourkovounia now comprises two distinct areas. The first one is now a grove while the second is an off-plan area at «Tourkovounia – Omorfokklisia» district and the former quarries. It consists of three hills axially mounted, with a strong presence of the damaged geophysical environment due to the exploitation of the quarry area. The limestone site is trapped within the urban fabric, which it abruptly interrupts, and it becomes an urban green island, completely surrounded by the city.
The proposal seeks to associate with the landscape created by the quarrying and the manner in which it was produced. There is an atttempt to conserve the terrain, by creating "canyons" and placing the buildings under arable land. This is a reversal of the city, which is now growing under the ground level and follows the relief of the landscape.
