4.2 Masterplan

Every city has pockets of underused and underutilized land or distressed and decaying urban areas. These pockets of underused land weaken the city’s image, livability, and productivity. They are usually the result of changes in the urban growth and productivity patterns. To tackle the issues of decline and urban decay, these cities and others around the world have designed complex processes of urban regeneration.

Urban regeneration involves the targeted use of public and private funding to regenerate a specific area of a town or city by making purposeful changes in the built environment as part of a larger master plan. It focuses on urban areas that are known to be experiencing higher levels of deprivation than the rest of the local population or that are in a state of decline. Urban regeneration seeks to create new opportunities both for the local community and individuals and businesses looking to invest in the area by repurposing underused or redundant land and buildings in a wholesale transformational intervention. There are three main types of urban

regeneration: economic, social and environmental, all of which have the core objective of promoting prosperity by reducing social inequalities in these areas, thereby improving people's quality of life.

Social, economic and cultural changes are forcing cities to modify and reorganize the living space on the basis of new principles and new development logic: from this point of view “urban voids” and underused spaces offer a great opportunity to rethink territorial functions creating new synergies between the public, private and tertiary sector.

5.1 Built-up Space Milano City Museum: A narrative about water and city

74

Traceback The site is located at Porta Genova railway station, which is the core of the Porta Genova. The train station is the oldest and currently in-use station in the city, witnessing the evolution of history and the urban landscape. Considering the decline in industrial activities and the emergence of new forms of urban connectivity, it is slated for closure and gradual dismantling.

Interaction As the intersection of two important urban axes, the tower's orientation and position respond to the axes, creating a visual connection with the historic district. At the same time, the old train station will be transformed into an open square to continue the historical trajectory.

Openings are processed on the facade to ensure the interaction between the tower and the city at different heights. The translucent facade material and the sunken square at the entrance enhance the permeability and openness of the boundary, providing opportunities for dialogue between architecture and the city.

Integration The city is a place of collective memory. In the natural change of urban history, the city that once existed has not completely disappeared. Instead, the memory of the city is continued through places, monuments, etc. We define this tower as Milano City Museum, connecting the evolution of Milan through Navigli, envisioning the future possibilities of the city. Through this museum, we aim to cultivate a sense of identity and belonging among people, extending the memory of Milan and Navigli into the future.

The ground floor of the museum is fully open to the public, with the entrance relocated to the underground level to enhance permeability and openness. It connects to the city through a sunken plaza. The underground level is linked to the ground floor via a water courtyard, where natural light refracted and reflected by water creates a unique spatial experience. The upper tower extends vertically into urban green spaces and water bodies, integrating with vegetation and water to become a new type of museum. Acting as a landmark, the tower also serves as a declaration of green commitment.

The assumed tour route begins at the entrance hall on the underground level, divided into four sections:

history of Milan

CITY MEMORY SQUARE_Ground Floor: The historical traces of the original train station are preserved, serving as the foundation for an open plaza where outdoor exhibitions can take place. Sunken plazas and shallow pools at both ends emphasize the memory of the old train station.

WATER EXHIBITION_Underground space: Featuring temporary exhibition halls, bar, auditorium, service areas, and interactive exhibits about water. This section aims to immerse visitors in the theme of water and its significance in Milan's history and future.

5.2 Connection Space Gallery Bridge: A connection between culture and agriculture

90

Traceback The bridge is located in the middle of the linear site.

Due to the limitations of this train yard, an important urban axis is severed: the art and cultural axis on the north side is suddenly cut off, and the accessibility of urban green space on the south side is also greatly reduced.

Interaction Facing the complex and diverse urban context, the bridge is no longer just connections in space, but also connections in life. The ground floor is completely open, with only two vertical circulation spaces leading to the galley and roof garden respectively. This preservation of the spatial character of the bridge base provides informal activity space for citizens, while also preserving the continuity of the entire linear green space and public space.

Integration Exhibition spaces and multifunctional room are placed inside the bridge, where nearby ar tists can hold exhibitions and events, attracting neighborhoods; the roof terrace also serves as the bridge deck, connecting to the green space at the other end. With the addition of the bridge gallery, a series of public spaces is established along this previously fragmented urban axis: the art and clutural district, art square, bridge gallery, ecological restaurant, and urban agriculture.

In the continuous open space under the bridge, the activities taking place are integrated with the surrounding life. The square at the end of the road of cultural and art district can hold temporary exhibitions; the sunken square at the entrance of the gallery can also be used as a open-air theater to hold performances; the bridge encloses the square with the original building in the south, can hold agricultural market on weekends.

The flow lines of the bridge and the gallery remain independent, intersecting only partially in the atrium to achieve spatial permeability. The interior space of the gallery is fluid, with a viewing terrace designed to over look the artistic and cultural street, encouraging interaction with activities on the street.

On the opposite end, service spaces are positioned, utilizing their thickness to create high windows that mitigate direct sunlight into the exhibition space.

At the same time, the height difference of the roof can naturally form a walkway.

5.3 Open Space Green house: A sustainable urban living room

102

Traceback The location of the green space was once an office and work zone, at the midpoint of the transition axis between agricultural formats outside the city and historical and cultural formats within the city.

The surrounding buildings still retain the roof character of the industrial buildings. At the same time, there are many museums and cultural buildings in the surrounding area, and Mudec is less than one hundred meters away from the site. On the south side of the site is the channel of the canal.

Interaction Facing the complex and diverse urban context, the bridge is no longer just connections in space, but also connections in life. The ground floor is completely open, with only two vertical circulation spaces leading to the galley and roof garden respectively.

The greenhouse has a total of two floors and a height of 10m. It is built on a 4.5M*4.5m grid and uses standard prefabricated materials. It is very easy to build and has little impact on the local environment. The facade material uses polycarbonate panels. The panels are lightweight, strong and easy to assemble. The special translucent material brings a different experience to the building and the interior space than ordinary indoor spaces. There are lush vegetation and trees around.

Many plants are also planted in the greenhouse, further blurring the boundaries between indoors and outdoors.
