“In 1999, class A office vacancy in the city was at 6.6%, leading developer Willard Rouse to envision a new tower. Cable company Comcast had been looking for possible new headquarters space in anticipation of the end of its lease in Centre Square in 2006. Comcast was looking for more than 400,000 square feet (37,000 m2) of office space and developers were actively courting the company for their developments. Comcast was the only employer in the city with major expansion plans at the time.” ~ Wikipedia
I look up to William Rouse for designing this sky-scraper. It’s really raised the bar for other architects as it take its place as the tallest building in Philadelphia and the 15th tallest in the country. I hope that someday I can bring myself to designing something to inspire other architects.
