Can’t say we’re surprised: In addition to a Four Seasons Hotel, the 60-story Comcast Technology Center will also include three high-end residential units.

Public records revealed that developer Liberty Property Trust sold three units ranging from 3,232 square feet to 7,738 square feet to FSP Realty, reports Philadelphia Business Journal. They’ve already found buyers, who purchased the units for $976.60 per square foot.

That comes out to $7.55 million for the largest unit. That’s still an impressive price tag, but still less than half the cost of the 500 Walnut penthouse, which sold for $17.85 million—the most expensive residential sale in the city’s history.

A representative for Liberty Property Trust would not comment on the sold residences at this time of publication.

Not much else is known about the residences, except that they’re pretty high up in the Foster+Partners-designed tower. They’ll have access to a private community terrace on the 45th floor; OLIN is the landscape architecture firm. It also probably goes without saying that the owners have a sway in the design of their units.

The tower still has a long ways to go until its spring 2018 opening. Here’s a sneak peek of the interiors amid construction.
