The main subject of this particular thesis, is the redesign of the waterfront of the city of Patras. Since a long time ago, the city has lost its relation with the sea, because the largest part of its waterfront, is taken over by the uses of the commercial and passenger port. But now, the city’s decision to relocate the passenger port onto another place of the city, frees up a big part of the city’s existing waterfront. So, the main goal is to make a realistic proposal, which will be structured by recognizing the area and its current situation, in order to establish all the uses that the area is in need and that will lead to an increased visiting rate of the city’s waterfront. Throughout the proposal, there is a presentation of the landscaping changes, that will generate big areas of trees and planting, and also spaces designed for the people to rest. Afterwards, all the plans of the proposed buildings are being presented, along with a series of sections and 3d images that demonstrate the idea at its best. The final proposal includes a cultural center - with auditorium, library and exposition spaces - an administrative center - with offices and meeting rooms - a commercial center - with bar, café, restaurant and an info point for the city - a sporting center - with tennis and basketball courts, a gym and locker room - and finally an open air food market that is established in one of the old warehouses of the port. All in all, what this proposal aims to achieve, is to rejuvenate and construct a strong relationship between the city and the sea, as every seaside city ought to have.
