15 Central Park West jedna je od najsuzdržanijih zgrada u New Yorku — od vapnenca iz Indiane, s prijeratnim proporcijama, disciplinirana posveta Roberta A. M. Sterna djelima Rosarija Candele i Carpentera. Stan 31B njezina je suprotnost: dom s dvije spavaće sobe i dvije kupaonice te gostinjskim toaletom, uređen prostoriju po prostoriju po uzoru na velike privatne pariške rezidencije — s ručno oslikanim štukaturnim stropovima, pozlaćenim i posrebrenim drvenim elementima, uklopljenim muralima i kupaonicama obloženima zrcalno sljubljenim mramornim pločama. Upravo je u kontrastu između zgrade i interijera poanta.

Dnevni boravak i blagovaonica nižu se uz park, a iz svake se prostorije kroz prozore od poda do stropa pruža nesmetan pogled na Central Park. Obje su uređene s reljefnim štukaturnim stropovima i kristalnim lusterima. U dnevnom boravku rezbarena rozeta ističe se na stropu, a bogato ukrašeni kamin na unutarnjem zidu. U blagovaonici su prizori vrtova uokvireni profiliranom štukaturom — detalj koji se češće viđa u velikim pariškim stanovima nego na Central Park Westu. Kutak za doručak povezuje blagovaonicu s kuhinjom, a njegova je klupa uokvirena slikom mrtve prirode.

Kuhinja je opremljena rezbarenim ormarićima s pozlaćenim detaljima, središnjim otokom od tamnog kamena i napom ukrašenom u istom stilu. Gostinjski toalet služi prostoru za primanje gostiju.

Spavaći dio nalazi se na suprotnoj strani stana, a prozori su okrenuti prema zapadu, s pogledom na otvoreno nebo i zalazak sunca. Glavna spavaća soba uređena je u blijedoj celadonskoj nijansi štukature, ispod kristalnog lustera. Garderobni ormar i garderoba vode do kupaonice s kadom za opuštanje ispod zrcalne mramorne ploče, dvostrukim umivaonikom i zidnim svjetiljkama. Spavaći dio zaokružuje druga spavaća soba s vlastitom kupaonicom i istom zapadnom orijentacijom.

Stanari zgrade 15 Central Park West imaju na raspolaganju privatni kolni ulaz, stalno osoblje, kino, igraonicu, fitness-centar s bazenom za plivanje od 23 metra pod krovnim prozorima, privatni restoran i vinski podrum.

15 Central Park West is among the most restrained buildings in New York — Indiana limestone, prewar proportions, Robert A.M. Stern's disciplined homage to Rosario Candela and Carpenter. Residence 31B is its counterpoint: a two-bedroom, two-and-a-half bath home finished through a room-by-room commission in the tradition of the great Parisian private apartments — hand-painted plasterwork ceilings, gilt and silver-leafed millwork, integrated murals, and bookmatched marble baths. The contrast between building and interior is precisely the point.

The living and dining rooms run in sequence along the park, each framing unobstructed Central Park views through floor-to-ceiling windows, and each finished beneath raised plaster ceilings and crystal chandeliers. In the living room, a carved rosette anchors the ceiling and an ornately detailed mantel anchors the interior wall. In the dining room, scenic garden panels are set into shaped plaster surrounds — the kind of finish more commonly encountered in a grand Parisian apartment than on Central Park West. A breakfast area connects the dining room to the kitchen, its banquette framed by a still-life panel.

The kitchen is fitted with carved, gilt-detailed cabinetry, a center island in dark stone, and a hood dressed in matching ornament. A powder room serves the entertaining spaces.

The bedroom wing sits across the residence, its windows oriented west for open sky and sunset views. The primary bedroom is finished in pale celadon plaster beneath a crystal chandelier, with a walk-in closet and dressing room leading to a bath with a soaking tub set beneath a mirrored marble panel, dual vanities, and sconce lighting. A second bedroom completes the wing with its own ensuite bath and the same western exposure.

Residents of 15 Central Park West enjoy a private motor entrance, full-time staff, a cinema, playroom, fitness center with a 75-foot skylit lap pool, a private restaurant, and a wine cellar.
