Comcast Corp. will lease 100 percent of the office space in its new skyscraper under contruction next to its headquarters in Center City, executive vice president David Cohen said in a Philadelphia real estate conference on Wednesday.

The $1.2-billion Comcast Innovation and Technology Center is expected to open in early 2018.

When Comcast announced plans for the tower in early 2014, the company said it would lease 75 percent of the office space.
