The Department of Planning and Development approved the project, which includes three new skyscrapers totaling some 3.3 million square feet, on Thursday.

The Seattle Times, which calls the project the largest ever proposed in downtown, reports that it could take up to six years to complete. also earlier this month secured an option on even more land in the neighborhood (illustrated by the orange arrow in the accompanying map).

“It is very important if we are going to treat this truly as open space that people feel invited into the spaces,” said NBBJ’s John Savo in remarks earlier this year in front of Seattle’s Design Review Board.

Last month, announced that it would pay $1.16 billion for its South Lake Union campus — located a short distance to the north along a streetcar line. As part of the agreement with the city, has agreed to subsidize the weekday operations of a third streetcar for 10 years.
