Executives at Boston Properties Inc. said work on the long-planned tower at 888 Boylston St. is scheduled to begin next month. The project, which will occupy the plaza next to the Hynes Convention Center, will include a total of 422,000 square feet of space, with about 60,000 square feet for retail stores.
The onset of construction was triggered by a lease with Natixis Global Asset Management, a financial firm that has made a commitment to occupy up to 150,000 square feet of the building. Boston Properties said it also is talking to national and international retailers about opening in the complex, but no leases have been signed.
“This may not be the tallest building ever built in Boston, but in many ways it will be the most important,” said Koop, adding that it will consume 45 percent less energy than the average office building and cut water usage by 37 percent.
