Mr. Maki’s Tower 4 at 150 Greenwich Street, between Cortlandt and Liberty Streets, is the most understated of the lot, with a sheer curtain wall. The 61-story tower rises for most of its height as a parallelogram and then, nearly 700 feet in the sky, it becomes a trapezoid, reaching an overall height of 946 feet, with no antennas. The upper part of the facade inclines toward the towers to the north and is meant as a unifying gesture.
