ORLANDO, Fla. -- The Walt Disney World Swan and Dolphin Resort will soon undergo a major expansion.

• Walt Disney World Swan and Dolphin to add hotel tower
• New hotel will be 14 stories with 349 rooms

A 14-story, 349-room hotel tower is set to be built on the complex, real estate firm Tishman and Metlife Investment Management, owners of the resort, announced in news release.

The tower will built next to the Swan Hotel on the space currently occupied by the hotel's tennis courts.

"We look forward to expanding the Walt Disney World Swan and Dolphin Resort and to marking the next chapter in our decades-long relationship with Disney," said Daniel R. Tishman, principal and vice chairman of Tishman, in a statement.

The tower will also feature more than 21,000 square feet of meeting space, a 75-seat restaurant, a full-service heath club with private changing rooms, a 90-foot long outdoor pool and an elevated deck with a fire pit.

The project is expected to break ground this fall and be completed by 2020.
