Green Roof: The Latest Architecture and News

Snøhetta has announced a project to rebuild the Refuge de Barroude, a mountain refuge located in a UNESCO World Heritage site in the Pyrenees Mountain range of France. The old building, destroyed in an accidental fire ten years ago, is set to be revived as a stop-off point for hikers on the Haute Route des Pyrénées and as a support center for the staff of the National Park. The next phase of the project is due to begin in 2025.

In increasingly denser urban environments, there is a new-found interest in underused spaces as opportunities for further development. Representing up to 25% of cities' land area, rooftops are among the most exciting spatial resources. From sustainable infrastructure and urban farming to social spaces and cultural venues, the article looks into the potential of creating a multi-layered city through the activation of urban rooftops.

Stefano Boeri Architetti, together with a multidisciplinary team including ARUP, Fabio Novembre, and Balich Wonder Studio, has unveiled the design for the new Milan Stadium, named the International Forest Stadium. The project, located in the San Siro area of the city, was presented to the public on the occasion of the competition announced in 2019 by the Inter and Milan teams. The stadium is envisioned as an integral part of the “Sport and leisure district” system, an extensive masterplan measuring over 800 hectares, planned to transform the San Siro district into a center for excellence in the context of European sports.

Büro Ole Scheeren has designed a new campus and experience center located in the historical city of Yibin, a region known for its rich cultural heritage and the geographical source of the Yangtze River. The campus was commissioned by Wuliangye, one of China’s leading winemakers. The project represents a large development inspired by the shape of a natural canyon, with two dynamic parallel structures defining a central space. On either side of this structure, called the Wuliang Interstice, are the Wuliangye World and the Wine Culture Exhibition Center respectively. Wuliangye World is an experience center where visitors can engage with the tradition of winemaking, while the exhibition center tells the story of wine culture through a series of themed exhibition halls.

The new apartment complex designed by Venhoeven CS and DS Landschapsarchitecten is characterized by the intention to stimulate biodiversity. Located on a four-acre plot in the Sluisbuurt on the Zeeburgereiland in Amsterdam, the complex will include 82 homes, a parking garage, and spaces for shops and businesses. The nature-inclusive project pays special attention to the design of green roofs, terraces, and facades to create micro-environments for local flora and fauna and to optimize energy consumption.

Sou Fujimoto has unveiled a “Not a Hotel Ishigaki”, a new project in the southwest of Ishigaki Island in Okinawa, Japan. The unique tropical resort hotel sits on a circular base open in all directions toward the surrounding natural landscape. The main feature of the building is the undulating roof covered in vegetation. Its shape allows access from the building terraces, creating an inner landscape, complete with meadows, relaxation areas, and a water mirror that reflects the sky and the singular tree in its vicinity.

Architecture in Mexico has a vast history that is made up of various aspects that touch astrological, political, spiritual and economic issues. Although today there are only ruins of some of the most important pre-Hispanic complexes, thanks to the in-depth research that has been carried out, we can have some representations of what those buildings that laid the foundations of what makes us today were like. In these representations, it is possible to notice the presence of natural materials that were a response to their environment such as basalt stone, stucco and some vegetable paintings whose remains persist to this day.

Researchers credit the Hanging Gardens of Babylon as the first examples of green roofs. Although there is no proof of its exact location and very little literature on the structure, the most accepted theory is that King Nebuchadnezzar II built a series of elevated, ascending terraces with varied species as a gift to his wife, who missed the forests and mountains of Persia, their local land. According to Wolf Schneider [1] the gardens were supported by brick vaults, and under them, there were shaded halls cooled by artificial irrigation of the gardens, with a much milder temperature than the outside, in the plains of Mesopotamia (present-day Iraq). Since then, examples of green roofs have appeared all over the world, from Rome to Scandinavia, in the most diverse climates and types.

Nevertheless, inserting plants on roofs is still viewed with suspicion by many, as they are thought to be costly and difficult to maintain. Others, however, argue that the high implementation costs are quickly offset with savings in air conditioning and especially that occupying the building's fifth façade with vegetation is, above all, a rational solution. In any case, the question remains as to how green roofs can really help with climate change.

Inspired by vernacular architecture, Kathryn Larsen is a bio-based designer working with seaweed. Throughout her career, she has been doing an intensive investigation into eel-grass, a material that has been used for centuries around the world. Larsen wants to apply all the benefits of this material (rot resistance, fire resistance, non-toxic, insulation characteristics comparable to mineral wool, and its ability to create carbon negative buildings) into prefabrication development and other technologies that enable the creation of new cladding and other elements, such as insulation batt and acoustic panels.

During the latest Design Indaba Festival, we had the chance to interview Kathryn. Read the interview and learn more about her work below.
