The transformation of a once dowdy stretch of 57th Street into Billionaires’ Row reached new heights on Tuesday, as two of New York City’s leading developers reached a truce that paves the way for two more ultraluxury towers on the northern edge of Midtown.

Like five others under development in the neighborhood, the two new towers will feature apartments selling for tens of millions of dollars and promising spectacular Central Park views.

Taken together, the seven high-rise buildings promise to remake the skyline and to redefine what it means to be rich in a city that is a cradle of capitalism and not so long ago was an emblem of urban poverty.

For seven years, the two developers, Gary Barnett and Steven Roth, blocked each other from moving forward with his respective superluxury project. But the men decided the time had come to settle, and on Tuesday, they signed a deal ending the feud.
