Dubai is known for having some underwater hotels and residential villas and now, it will also have an underwater complex. The promoter of this concept is a polish architect Krzysztof Kotala of 8+8 Concept Studio.

Kotala says the underwater tennis complex is an innovative approach to sports facilities. The complex, which consists of seven arenas, works as a sports, recreation and exhibition centre.

“The underwater arena fits into the natural environment because it resembles a coral reef in Dubai. Modern technologies and environmentally-neutral materials such as nano‐cement and carbon glass can be used for the construction.”

Besides the emirate, he says Qatar and Japan could also be ideal locations for building such a stadium. Dubai is the host for World Expo 2020, which is expected to bring 25 million visitors to the country, while Qatar will hold the Fifa World Cup in 2022. According to Krzysztof Kotala, Qatar and Japan could also be ideal locations for building such a stadium.
