Inspired by an idea by Stefano Boeri and with a landscape design by AG&P greenscape, the project by Stefano Boeri Architetti and Arassociati is located in an ex-industrial area overlooking via San Cristoforo and the future railway line park due to the closure of the railway system. The line park will link Porta Genova with the Naviglio Grande canal. This zone is undergoing vast transformation, and is conveniently connected to the Zona Tortona Design District.
The area includes historical and environmental heritage sites needing urgent protection; the Naviglio Grande canals and the ancient church of San Cristoforo, the cascina Campagnola farmhouse and the Canottieri San Cristoforo canoe club headquarters. Unlike many of the projects featured in this book, this intervention is located outside the historical city centre, and has therefore provided the architects with the opportunity to express its ideas in a context free of many of the usual restrictions, to focus completely on contemporary perspectives. The building is situated in an open environment surrounded by green woodland and the project will be strongly focussed on energy efficiency.
In this context, it will also play a crucial role in connecting the densely constructed urban fabric with an open, irregular space where trees and landscaping form the unifying element. The residential project is composed of apartment buildings around a central courtyard to guarantee necessary privacy and seclusion, while maintaining a close connection with the surrounding context. This explains the difference in facade design on the sides facing in towards the courtyard or out towards the urban space. The internal facades are composed of recessed loggias, while the external facades feature an irregular arrangement of densely planted balconies, including tall trees that act as an acoustic barrier and help abate atmospheric pollution.
The architectural design is based on a rising spiral, where the facades overlooking Via San Cristoforo and the future railway line park gradually curve inwards to form the internal courtyard, taking advantage of the progressive variation in height to create a descending series of planted terraces in close harmony with the surrounding landscape. This system is the result of innovative research for environmental protection and sustainability, as an answer to “post pandemic” living requirements because of the need for open spaces and accessible green areas. From an environmental viewpoint, the incorporated solutions provide pollution abatement, and solar panels have been integrated into the entrance roofing. The entrance is double height and partly enclosed to house the guardian’s quarters. It defines and determines the form of the internal courtyard. The vast woodland project surrounding the building makes a strong contribution to the local urban redevelopment scheme; other projects associated with the tree planting interventions include new garden landscaping in Piazzale delle Milizie, and the transformation of the former municipal recycling centre into a green space. Special attention was paid to the presence of a large solitary elm tree which has become the focal centre for the redevelopment of Via San Cristoforo.
