Top floors of Macy’s flagship evolving from Frango mints and furs to thousands of office workers

Developer Brookfield Properties is in the midst of converting those floors to about 650,000 square feet of modern offices. The transformation is expected to cost hundreds of millions of dollars, including the purchase price, changes to the structure and leasing costs.

Last year, Brookfield Properties bought floors 8 to 14 of the building from Macy’s for $30 million. The real estate investment giant, an arm of Toronto-based Brookfield Asset Management, plans to open the space to tenants by May.
