Interviews: The Latest Architecture and News

Sand is the most-consumed natural resource in the world after water and air. Modern cities are built out of it. In the construction industry alone, it is estimated that 25 billion tons of sand and gravel are used every year. That may sound a lot, but it’s not a surprising figure when you consider how everything you’re surrounded with is probably made of the stuff.

But it’s running out.

This is a scary fact to think about once you realize that sand is required to make both concrete and asphalt, not to mention every single window on this planet. The United Nations Environment Programme found out that from 2011 to 2013, China alone used more cement than the United States had used in the entire 20th century and in 2012, the world used enough concrete to build a wall around the equator that would be 89 feet high and 89 feet thick (27 by 27 meters).

Artist Christo has released images of his proposed temporary sculpture for Hyde Park, London, to become his first major outdoor public sculpture in the United Kingdom. Titled “The Mastaba (Project for London, Hyde Park, Serpentine Lake)," the sculpture will consist of 7,506 horizontally-stacked barrels floating on the Serpentine Lake throughout the summer of 2018.

“The Mastaba” will coincide with an exhibition of Christo and Jeanne-Claude’s work at the Serpentine Galleries, featuring sculptures, drawings, collages and photographs spanning more than 60 years. Supported by Bloomberg Philanthropies, the exhibition will be the artists’ first in a UK public institution since 1979 and will showcase their long-running exploits with barrel forms, chosen initially for their sculptural effect and low cost.

How can the future design and configuration of cities promote greater sustainability in the conditions of urban life? Dust to Dust: Redesigning Urban Life in Healthy Soils is an urban design ideas competition, supporting the UN Sustainable Development Goals.

For the "Imagine Angers" international design competition, Vincent Callebaut Architectures worked in collaboration with Bouygues Immobilier group to submit a proposal for the French city at the intersection of social and technological innovation, with a focus on ecology and hospitality. Named Arboricole, meaning “tree” and “cultivation,” this live-work-play environment gives back as much to the environment as it does its users. Although WY-TO prevailed in the competition, the Callebaut scheme succeeded in winning the public vote.

French firm Coldefy & Associates has unveiled images of their design proposal for the world’s largest tropical greenhouse under one roof. Situated in Pas-de-Calais, France, “Tropicalia” will cover an area of 215,000 square feet (20,000 square meters) featuring a tropical forest, turtle beach, a pool for Amazonian fish, and a one-kilometer-long walking trail. The biome aims to offer a “harmonious haven” where visitors are immediately immersed in a seemingly natural environment under a single domed roof.

Within a week of its successor being awarded the Silver Lion at the 2016 Venice Biennale, the original Makoko Floating School collapsed. Designed by Nigerian architect Kunlé Adeyemi of NLÉ Architects, the school was located in the Lagos Lagoon in Nigeria. Now, almost two years later, Lagos-based writer Allyn Gaestel has investigated the vulnerable coastal community and architect behind the project in a remarkable narrative nonfiction piece, "Things Fall Apart."

Aedas' latest project is inspired by the tech cloud as a platform to boast connectivity within the mixed-use development and enable maximum productivity between the zones. Vanke Tianfu Cloud City will be within the new development zone in Chengdu, China designated for new hi-tech and sci-tech industries and provide offices, exhibition, residential and retail facilities.

Chicago-based Skidmore, Owings and Merrill (SOM) have won an international competition for the design of an enhanced urban district in Charenton-Bercy, on the eastern edge of Paris. Working with a team of urbanists, landscape designers and community think tanks, SOM have proposed a highly connected urban landscape incorporating a 180-meter energy efficient tower, and contemporary rotunda serving as a virtual reality hub.

In the 3rd Arrondissement of the French city of Lyon, construction has begun on Lyon Part-Dieu, an MVRDV-designed scheme seeking to transform the city’s main shopping center. Featuring partly-transparent glass and a public green roof, the MVRDV scheme will revitalize and integrate what was formerly an introverted complex built for an era dominated by the car.

At 166,000 square meters, Lyon Part-Dieu is the largest downtown shopping center in Europe, built in 1975. In order to improve the existing outdated complex, MVRDV worked with co-architects SUD to produce a design that offers a contemporary update to the existing façade and a re-organization of the interior program.

Guangzhou-based multidisciplinary firm O-office Architects specializes in refurbishment projects. Founders Jianxiang He and Ying Jiang are known for exploring what architecture can do within the contemporary Chinese context, including a recent project in which they transformed an abandoned Shenzhen factory into a dynamic cultural and community center.

In this interview with ArchDaily, the founders of O-office speak about their philosophies regarding refurbishments and the current state of architecture in China.

In an era defined by globalization, and ‘speed-driven economies,’ urban environments are becoming more entwined with airports, giving rise to an architectural phenomenon of the ‘Aerotropolis’ across the world. In Oslo, Norwegian firms Haptic Architects and Nordic Office of Architecture have aimed higher, seeking to design the world’s first energy-positive airport city for the Norwegian capital.

LEGO is going green. The Danish company has announced that they have begun production on a range of pieces made from a plant-based plastic sourced from sugarcane.

As a nod to their plant-based origins, the first sustainable pieces will take the form of LEGO botanical elements such as leaves, bushes and trees.

After a successful project in Uruguay—the first in Latin America—it's now Argentina's turn to build its first sustainable public school. The design will use the recycled materials of "garbage warrior" Michael Reynolds, the founder of Earthship Biotecture, and will be constructed as part of the program "A Sustainable School" in the unique biosphere of Mar Chiquita, in the Province of Buenos Aires, from March 1 to 28.

Read on for more information about the new project.

Following recent natural disasters including the Northern California wildfires, the HASSELL + team have been inspired to reimagine the San Francisco Bay Area as a vibrant community hub, equipped to provide temporary facilities in an emergency. As part of the competition Resilient by Design, the ten teams were asked to provide solutions for the waterfront through site-specific conceptual design and collaborative research projects.

A 100-meter-tall air purification tower in Xi’an, China – believed to be the world’s largest air purifier – has significantly improved city air quality, results from its preliminary run suggest.

According to researchers from the Institute of Earth Environment at the Chinese Academy of Sciences, the tower has managed to produce more than 10 million cubic metres (353 million cubic feet) of clean air per day since it was launched a few months ago. In the 10-square-kilometer (3.86-square-mile) observed area of the city, smog ratings have been reduced to moderate levels even on severely polluted days, an improvement over the city’s previous hazardous conditions.

Sustainability. A word that, for many of us, has been driven into our minds from the very start of our careers as architects. We have a responsibility to the planet and future generations to design buildings that are socially conscious—from solar panels to triple-glazed windows, we have tried it all.

Ultimately, whether our designs are sustainable comes down to the early decisions we make for the building, with our choice of materials having a huge effect on the overall carbon footprint. With new technologies come new ways of incorporating abundantly found materials into the skin of the building that could reduce the building's embodied energy and enhance the structure's properties.

In this article, we have compiled a list of 8 familiar materials that you wouldn't initially associate with sustainability but which you might consider for your next design.

The SDG Academy online education platform recently launched a series of free online courses on topics ranging from sustainable development and urbanization to climate change and the use of natural resources.
