Only a few years after commissioning architect Rafael Viñoly to convert a Lenox Hill townhouse into an extended penthouse, billionaire Eduardo Eurnekian has up and listed the place. Viñoly—the architect behind current residential high-rise crown of Manhattan 432 Park, as well as numerous other projects including Jazz at Lincoln Center—is an enormously influential architect, and interest in Eurnekia’s new townhouse has generated substantial interest.

So onto the market it goes, with an asking price of $50 million. A nice round figure, with an appealing cleanness, and a lack of the price-charm absurdity sometimes attached to homes tagged with multi-million dollar asks.

The façade of the house is literate, playful, and open, with arched glass panels and red-trimmed picture windows presenting a living style that looks extremely inviting. As expected, the interiors—which extend to about 10,400 square feet—follow suit, with generous proportions,  and a huge skylight bringing in yet more natural light.

The effect of the interiors is a startling feeling of liberation. The interior design style is pared down to almost an abstraction; a nearly complete lack of ornament would prevail if it were not for the bookmatched slab marble used in the baths, so the residence is a blank canvas of sorts at present. The listing details use the word ‘timeless’, and clearly desire to tap into a lesson learned from modern interiors: ornament dates fast.

There are six bedrooms in the home, all en suite, and an additional two baths. A rooftop garden and a rear terrace provide exterior living space.

Eurnekian is an Argentine entrepreneur who made his money in media, among other things. His net worth is estimated to be $2.7 billion.
