One Way Street A city history is like a one way street (einbahnstraße): you can keep traditional forms, but you have to change the way one uses them. If you don’t regenerate the city with new spaces and technologies, you will create a fake city. If you don’t deal with the pre-existing architectural and urban forms, you will loose the identity of the city and you will produce a inept architecture. These three projects interact with the existing buildings on the sites as well as the traditional building typologies around, changing their use and perception thanks to new physical or visual links. These links are either formed with an architectural element or hollow space. For instance, the reticular structure transforms the old train station and maintenance facilities into a unique entity (“kulturforum”). However the two others are public spaces that link different types of urban entities which were originally separated from each other.Landscape Wittstock urban shape is clear and unspoiled thanks to the green belt around the old walls. This belt is an important heritage, that each urban project had to deal with. The old railways tracks become a linear park, connecting the former station complex to the Thirty Years War Museum. This park crosses the green belt and their intersection generates a public open space that we called “events esplanade”. This new green “platz” perspectively ends in front of the former railways warehouse curved façade and it is a sort of public and modern twin of the old Amtshof. Also the housing projects in Werderstrasse and Kyritzer Strasse deal with green spaces: many dwellings have a private green loggia and each complex faces on a public court that is a collective garden.Project Site 1 “Bahnhof” A suspended reticular structure crosses the railways lines still in use and connects the old train station to the other railways facilities. Between the buildings, flat roofs cover the public areas and the entire system becomes a center for studing and developing the identity of the city, hosting archives, classrooms for university workshops, exhibition areas and offices. A new bridge over the Grinze river leads to the Thirty Years War Museum generating a linear cultural complex at the old town gates. We called it “Kulturforum”. The reticular structure is composed by modular units so that it can be realized in several phases. The wide covering surface could hosts photovoltaic panels.Project Site 2 “Werderstraße” The new housing complex closes the north side of Werderstrasse, according with the gothic city rules. This respectful historical approach lead us to a linear complex where each unit shifts to follow the irregular street border. That generates large openings hold by steel frameworks, recalling the traditional wood ones we can see in the pre-existing houses all around. Dealing with traditional forms and materials (like bricks), this project presents a really new way to inhabit the gothic block. Traditionally, openings are only on the street façade and on the backyard one, whereas in our project the other two sides manage the inside/outside connection and generate sidelong sights on the city.Project Site 3 “Kyritzer Straße” The original “L” shaped block is an important landmark to enphasize the city entrance. We decided to mantain its huge mass and to rehabilitate it improving its permeability. A two-storey hole connects the little square beyond the street with the block inner court. That generates a transversal public square, whose shape is re-defined by two small pavillions. The one in the block court hosts neighbourhood facilities. The other one is a turistic info point, clearly visible from the roundabout, engaging Kyritzer Strasse by car. Inside the block, we replace some dwellings with offices on the ground floor and on the first floor. On the other two floors, dwellings interior design is upgraded with open spaces and green loggias facing the inner court garden. In this way, the street façades remain massive whereas the court façades (the more private ones) become porous.
