Home to an abundance of wealth as well as the world's tallest building, Dubai is already one of the most extravagant locales on the planet. But the opulent city isn't resting on its laurels as officials have announced plans to construct what will be the world's first climate-controlled bio-dome.

The Mall of the World complex will be an undertaking unlike any other. Covering 48 million square feet, the mini-metropolis will feature the world's largest mall as it'll occupy 8 million square feet alone.

Other areas will be split into districts specializing in a variety of amenities. For example, a wellness district will offer up services like cosmetic surgery and spa treatments while the cultural district will mimic famous landmarks around the globe like London's West End and Rodeo Drive in Beverly Hills.

Elsewhere, visitors will find more than 100 hotel and serviced apartment buildings in addition to the world's largest indoor family theme park. Some 20,000 hotel rooms will be available for guests at any given time while a cultural celebration center can play host to 15,000 people.

In a statement on the matter, Dubai ruler Sheikh Mohammed bin Rashid al-Maktoum said the growth in family and retail tourism underpins the need to enhance Dubai’s tourism infrastructure as soon as possible. The project complements their plans to transform Dubai into a cultural, tourist and economic hub for the 2 billion people living in the surrounding region and they are determined to achieve their vision, he added.

No word yet on how much the project will cost or when it will be completed.
