Downtown Circle: Dubai architects design giant ring around Burj Khalifa

written by Nadia Lee Hewitson, CNN

In Dubai, experimental architecture firm ZNera Space proposed a conceptual design featuring a massive five-story circular structure surrounding the world’s tallest skyscraper, the Burj Khalifa. Amazing 829.8 meters (2,723 feet), nearly twice as tall Empire State Building.

Known as Downtown Circle, the concept is a highly ambitious design brought to life by a series of compelling illustrations created in collaboration with Pictown, a company that specializes in architectural renderings. It connects urban planning.

Najmus Chowdry and Nils Remess, principal architects of ZNera Space, envision the Downtown Circle as a horizon to Dubai’s dizzying, futuristic skyline. Skyscraper.

The Downtown Circle may be a compelling and radical design, but for now, Chawdhury and Lemes admit, it’s both realistically and economically implausible.

“It was meant to be a conversation starter,” Chowdhury said. “Something that inspires people to rethink urban development and rethink urban congestion…we are committed to sustainable cities.”

“We were working on a very important aspect that caused a debate about how we were planning the city,” Remes added. “We chose the Burj Khalifa because it is in a very dense urban area and we wanted to address the issues that come with dense urban populations.”

Intended to sit 550 meters (1,804 feet) above the ground, the structure is more than 3 kilometers (1.8 miles) in circumference. The ring he is supported by five massive pillars, the base of which is in a clearing and may serve an additional purpose.

“We wanted to create a kind of envelope around the area to create a microclimate downtown, to control the temperature and make it more livable in hot climates,” Chowdhury said. “You can use those vertical [pillars] As an air purifier in the city. “

Sustainable design for the future

In Dubai, temperatures often exceed 40 degrees Celsius (104 degrees Fahrenheit). The architects hope the design will set a new benchmark for sustainability in the region.

“The whole ceiling will be solar panels,” Chowdhury said. “What we want to do is implement a technology that we have already used in previous projects, solar hydrogen cells.”

This technology uses solar energy to convert water into hydrogen, which can power air conditioning and provide energy to buildings.

The concept also proposes end-to-end transportation options, such as an electric tram system that can reach speeds of 100 kilometers (62 miles) per hour, and infrastructure to accommodate sky taxis.

“Self-reliant” cities

Such architectural ambitions would not come without engineering challenges, such as creating a structure that is strong enough to house its internal functions, yet lightweight enough to be supported by columns.

“The structure itself is very light. I imagine it like a (big) aircraft. The structural skin, the ribs, the interior are all hollow,” Chowdry said.

“But it’s supported by these pillars and annuli,” he continued.

The proposed Downtown Circle will weave residential spaces between commercial, corporate and cultural areas to form an inclusive “city within a city of self-sufficiency,” said Remess. “If you live there, you can go to the office, you can go to the park, you can walk home and he can be there in 15 to 20 minutes. In Dubai, it is difficult.”

An interior highlight of the design is a continuous green belt called SkyPark that connects all five floors of the structure.

“SkyPark is the central backbone of the entire design,” explains Chowdry. “It will be a mixed-use green space that also serves as a space for rethinking how agriculture could take place in the future, especially in cities.”

“Historically, agriculture started first, then cities were built,” says Remes. “Now we have lost this concept. With this greenbelt within the structure, we want to bring agriculture and food production back to the city centre.”

The concept certainly gets some attention, but it’s not all positive. Since posting the mockup on the company’s Instagram page, some commentators have said the design could destroy the structure of the downtown district.

“Some of the comments online are negative, but as someone recently told us, which one looks better, an empty finger or a finger with a ring on it?” Chowdhury said. . “I think it just adds to the verticality of the Burj Khalifa.”
