The most talked-about building in New York City over the last several years doesn’t exist. That would be the Freedom Tower, the centerpiece of the World Trade Center reconstruction project. But If you’re like me and have a short (or even medium-level) attention span, you’ve lost track of what the Freedom Tower’s going to look like, when it’s going to be built, whether it’s going to be 1,776 feet tall…

Happily, lots more of note has been going on (and up) in Manhattan—an island known more for its frantic pace of construction than its design brilliance. That’s why a spot like Diller Scofidio + Renfro’s revamped Alice Tully Hall in Lincoln Center is most welcome (so welcome, in fact, that extra seating was added in the airy cafe due to overwhelming demand).

Those same architects oversaw the transformation of the High Line, the old elevated freight railway on the West Side, into a public park. The first stage is finally open, and if you’ve been in the area on a recent weekend, you know people are taking advantage.

Near its southern end, the High Line is straddled by another striking new addition to the skyline—Andre Balazs’s Standard Hotel, a slender glass tower (above) offering stellar views in all directions. I’ll definitely be hanging out at the 18th-floor bar when it opens later this summer.
