The United Arab Emirates (UAE) plans to build the world’s first temperate-controlled city in Dubai in a bid to become a year-round tourism destination despite soaring temperatures in summer that can reach nearly 50 C.

The city will be built on 48 million square feet which will contain the largest shopping mall on the planet, complete with climate-controlled streets, the world’s largest indoor theme park and 100 hotels and apartments.

Other facilities such as the health resorts, theatres, a Celebration Street modeled on the Ramblas boulevard in Barcelona and ‘retail streets network’ that will stretch over four-and-a-half miles, will also be part of the city.

A glass dome will be built to cover the city-within-a-city which will open during the cooler winter months to allow people to sop in the fresh air while the city will be covered by the dome during summer.

“This project complements our plans to transform Dubai into a cultural, tourist and economic hub for the two billion people living in the region around us; and we are determined to achieve our vision,” Sheikh Mohammad Bin Rashid Al Maktoum, the emirate’s ruler and vice president of UAE quoted by The Daily Mail said.

He also added that, “The growth in family and retail tourism underpins the need to enhance Dubai’s tourism infrastructure as soon as possible.”

“We are confident of our economy’s strength, optimistic about our country’s future and we continue to broaden our vision,” he said.

The supersized mall will be built near the existing Mall of the Emirates, already one of the largest shopping centres in the world, with its own indoor ski slope.
