The design proposal of the Kapnergati Square area, a central public space in Northern Greece, aims to unify and organize the site itself as well as its greater context, creating an important urban center for the city of Kavala and focuses on the creation of three urban themes: urban square, interactive playground, pedestrian streets. Additionally a fourth system of prismatic structures is being proposed which acts complementary to the three above mentioned themes, as a threshold of concave and convex spaces in- between them. Finally, a sustainable and bioclimatic approach in terms of the materiality, plantation and artificial lighting system of the urban space has also been adopted as a key design strategy.
