Description

Perfectly designed.

This beautiful high-floor residence is positioned steps from both Madison Square Park and Chelsea, in the heart of the Ladies Mile Historical District, in a prewar 1904 loft building. Sunlight from two exposures and 10-foot ceilings broaden the condominium apartment's expansive appeal.

The key-lock elevator leads into the main living room, smartly appointed with burnished hardwood floors, open dining area, and a stone-clad working fireplace. The Valcucine kitchen features custom cabinetry, appliances from Sub-Zero and Miele, and special touches like warming drawer, built-in coffee machine, and pot-filler. The flexible layout includes two large bedroom suites, plus a third room off of the third full bath perfect for a library, study, media, or home office. The master bath is particularly well-appointed with imported stone, oversized glass shower, built-in flat-screen TV, radiant floor heat, and private W.C. Generous closets, multi-zone central climate control, and a separate laundry room emphasize the ease and comfort of living.

Altair 20 is an intimate portfolio of 17 loft residences converted in 2006. Thoughtful amenities include a multi-level roof deck with gas grill, private storage, and fitness center from La Palestra. The lobby is attended daily.
