The architect transforming cities into ‘vertical forests’

By Oscar Holland
Stefano Boeri’s tree-covered towers in Milan won critical acclaim. Now he’s taking his urban forests global.

Architect Stefano Boeri has always been obsessed with trees. The Italian traces his fascination back to a novel he read as a child, “Il Barone Rampante” (“The Baron in the Trees”), in which a young boy climbs up into a world of trees and vows to never to return.
“I think trees are individuals,” Boeri said in a phone interview. “Each has its own evolution, its own biography, its own shape.”

Unsurprisingly, there is child-like wonder to the architect’s best-known building, Il Bosco Verticale, or the Vertical Forest. Built in his home city of Milan, the celebrated complex teems with greenery, its facades transformed into living, breathing organisms.

The project’s two residential towers — measuring 80 meters (262 feet) and 112 meters (367 feet) respectively — play host to around 20,000 trees, shrubs and plants. They spill out from irregularly placed balconies and crawl up the structures’ sides. By Boeri’s estimates, there are two trees, eight shrubs, and 40 plants for each human inhabitant.

The purported benefits of this garden architecture transcend aesthetics. Greenery, supposedly, provides shade to apartments, psychological benefits to residents and a home to wildlife. (There are, Boeri said, “hundreds of birds, more than 15 different species” nesting on the towers’ various floors.)
But the architect’s proudest claim is that the buildings absorb 30 tons of carbon dioxide and produce 19 tons of oxygen a year, according to his research, with a volume of trees equivalent to more than 215,000 square feet of forestland…

In September, Vertical Forest was named among four finalists for the RIBA International Prize, a biennial award honoring the world’s best new buildings. Amid the plaudits, Boeri claims the project’s real success is that it serves as a prototype.
The architect has far more ambitious designs. His firm has already unveiled plans for new Vertical Forest buildings in European cities including Treviso in Italy, Lausanne in Switzerland and Utrecht in the Netherlands.

In the Chinese city of Liuzhou, Guangxi province, he has masterminded an entire “Forest City,” scheduled for completion in 2020, which comprises tree-covered houses, hospitals, schools and office blocks over a sprawling 15-million-square-foot site. (Boeri said that he’s also been approached about producing similar “cities” in Egypt and Mexico.)

This Toronto skyscraper is covered with 450 trees

A new tower will have greenery lining the balconies and roofs to clean up the air and provide a new environment for pollinators and humans alike.

Toronto has long been serious about its urban canopy. The Ontario city is already home to around 10 million trees, which cover around 26% of the city. The current mayor, John Tory, wants to grow that to 40%.

Brisbin Brook Beynon, a local architecture firm, is already giving the city a leg up on that goal, albeit in an unconventional way: a 27-story residential building that will be covered with around 450 trees, growing on its balconies and roofs. This “vertical forest,” as BBB terms it, takes inspiration from the Bosco Verticale–residential towers in Milan that went up in 2014 with as many as 11,000 plants lining the sides. Since then, copycat buildings have been built in cities like Nanjing and in Taiwan–designed to combat pollution and prove that green space does not need to be limited to the ground. This latest iteration could open as early as later next year.

For Brian Brisbin, principal at BBB, bringing the vertical forest concept to Toronto aligned perfectly with the mayor’s goals for increasing tree coverage. And when he began researching the concept by studying the Bosco Verticale, he realized that all of the technology that enabled the Milanese building to function originated in Canada and North America. “That felt fairly profound,” Brisbin says.

And it also, Brisbin says, made bringing the concept to Toronto feel much more feasible. “We have a lot of depth of specialty in this area in Toronto, with horticultural and agricultural universities and research facilities,” he says, “and we’ve brought a lot of together to take a very science-based approach to developing this project.”

This Concept Uses a Pre-Fabricated Timber System to Enable Modern, Self-Built Homes

Space Popular’s design gathers service functions into a central prefabricated core (resembling a Nordic hearth) that DIY-ers can build their own house around.

Solutions from the past can often provide practical answers for the problems of the future; as the London-based design and research firm, Space Popular demonstrate with their “Timber Hearth” concept. It is a building system that uses prefabrication to help DIY home-builders construct their own dwellings without needing to rely on professional or specialized labor. Presented as part of the ongoing 2018 Venice Biennale exhibition “Plots Prints Projections,” the concept takes inspiration from the ancient “hearth” tradition to explain how a system designed around a factory-built core can create new opportunities for the future of home construction.

Realized in the form of a brightly-painted model in the exhibition space at Serra dei Giardini, the Timber Hearth system gathers all the service functions, appliances, and fittings that require professional installation in typical residential buildings and contains them within a prefabricated hearth-like structure.

Fabricated in a factory and sized for shipping in one piece, the core is then installed on site and connected to service grids. After that, the remaining construction (including building the floor platforms, partition walls, facade, and roof) can be completed by the homeowners, either by traditional or contemporary timber-frame methods. According to the designers, this affords reasonably-equipped makers the flexibility, freedom, and affordability to build their own perfect home.
