Saudi Arabia's 3,000-foot-tall skyscraper will have the world's highest observation deck

Rising to a staggering 3,281 feet tall, Saudi Arabia's Jeddah Tower could one day set a world record as the tallest skyscraper on Earth. It will also have the world's tallest observation deck.

Located in Jeddah, Saudi Arabia, it's the brainchild of SWA Architects, the same firm behind the current world's tallest building, Burj Khalifa, in Dubai.

It's slated for completion sometime in 2019.

Here's what it'll look like.

Jeddah Tower will feature an extensive network of restaurants, hotel rooms, apartments, parks, and a shopping mall. Basically, it's a city inside a skyscraper.

One of the tower's key features is its observation deck, located on the building's 157th floor. That's 55 stories higher than the deck at New York City's Freedom Tower, making it the tallest observation deck in the world.

Jeddah Tower will cost the Jeddah Economic Company and Saudi Arabia's Alinma Investment — the two groups financing the project — roughly $2.2 billion. That's about $700 million more than it cost to build Burj Khalifa and $1.6 billion less than the Freedom Tower.
