Australian financial firm ups Midtown space

The Australian financial services firm Macquarie Group just signed a lease for six more floors and portions of two other floors at 125 West 55th Street, in addition to renewing its existing lease of 100,000 square feet in the building. Harry Macklowe sold the 591,000-square-foot building earlier this year to Boston Properties for $440 million. Sources say the building is fully leased and the new rent starts at about $90 per square foot.
