One in, one out.

This month, T-Mobile CEO John Legere took ownership of a South Florida estate. The 6,240 square-foot addition to Legere’s real estate portfolio siphoned $16.7 million from his coffers, but offers the laid-back Gulf Coast living style and a Port Royal community location as compensation.

Not bad, but the outgoing property deserves a few words, too. The prewar Manhattan penthouse is spectacularly beautiful, and considered one of the finer residences in the city; as one of the last period-intact penthouses in New York, it is sold with a substantial turnkey style—neo-Tudor—with knee-bucklingly beautiful stained-glass windows, Tudor arches, delicate millwork, ornate plaster ceilings, abundant carved wood, and a restored elevator among its historical surprises. The buyer of the property speaks volumes about the home’s cachet—it was purchased by Giorgio Armani.

The kitchen’s restaurant-grade design sense adds another layer of complexity to the living style, while the four bedrooms all feature very individual treatments. The exterior living area is also expansive—a terrace that offers 100’ of Central Park frontage.

The condo is located in 91 CPW, a building completed in 1929. The exterior—in brick, terra cotta and stone—is neoclassical in style, with Beaux Arts elements adding a bit of ornate embellishment to the façade. The building rises 16 stories above terra firma; the unit in question is the crown jewel of its 94 residences.
