MKCA's Bold, Refined Renovation of a Carnegie Hill Apartment

Cerused oak millwork with three-inch-deep coffers lines the entire gallery and circulation zone. While the paneling’s rigorous geometry contrasts with the fluid, curvilinear pattern of the floor, it is engineered to enhance the apartment’s flexibility. Leading to the den and dining room, the paneling swings closed as a pair of integrated doors with wood handles. In the gallery, lighting and hidden art hanging rails are integrated subtly into the millwork, creating a flexible display system for the family’s rotating collection of contemporary photography.

Elsewhere, millwork volumes open to reveal a hidden liquor cabinet in the living room, a home office in the den, and a concealed, lift-up television and integrated display for a collection of glass artworks by Yoichi Ohira in the dining room. Paneling likewise conceals a powder room with a spectacular blue marble vanity and integrated cove lighting. All can be opened and closed with ease, catering to a range of scenarios. 

The subtle detailing of a millwork wall that reveals a pair of doors produces a visually rich and tactile environment that can be manipulated to create different spatial and social configurations. The merging of functions at all scales—from rooms that serve multiple purposes to shape-shifting furniture pieces—is a hallmark of MKCA’s overarching practice and an essential component of this residence. Here, it supports the family’s desire for flexible spaces that can be used either independently, by individual members of the family, or collectively. 

For instance, the dining area and library are fused into one, and the furniture anchoring this room transforms depending on the scenario: The table expands, the banquette breaks apart into chairs, and the chandelier swivels to the center of the room for seamless transition between family meals and formal/entertaining settings. Similarly, a large single seating group in the living room can be arranged to support numerous semi-independent zones or brought together for a group gathering. “Porosity between the dining area/library and living room means that people slip in and out of the rooms with ease. It’s a space for casual family meals, reading, hanging out, playing games; and it’s also a space for dramatic, large-scale, formal entertaining,” says Chen.

In keeping with MKCA’s overarching practice, the studio has designed and commissioned custom furniture across the home, with each piece bolstering the project’s emphasis on mutability, tactility, and elegance. The latest result of an ongoing collaboration between MKCA and Christopher Kurtz, the Hudson Valley-based sculptor and designer’s striking 12-foot-long dining table anchors the dining area/library. The piece features an undulating, carved aluminum top fused to a rippling underlayer and base in oxidized cherry, while a custom chandelier by Ladies and Gentlemen Studio hovers above, rotating softly on a custom mechanism. "We created a process where the collaborating designers were always aware of each other's work throughout. As with all of our interiors, our approach has as much to do with connecting and creating an actual dialog between collaborators as it does with curating relationships between objects,” says Chen.

In the kitchen, a muscular island with hefty stone legs is set against ribbed walnut paneling, while the main bath is enveloped in rosy venetian plaster, pink Byzantine onyx, and Calacatta Vagli Rosato marble. Throughout the living room, Kurtz’s custom carved wood sconces are enveloped within the thickened wall around the fireplace and glow gently through an integrated LED array, while his game tables and chairs resemble stacks of “pebbles” made from a mix of woods (oak, walnut, maple, cherry) and metals (aluminum and bronze). These are paired with a Poritz and Company’s custom butterfly bar, whose tambour doors open to reveal a glitzy mirror and glass interior for entertaining, as well as a “Merrick” daybed by MKCA covered in a graphic chenille by Castel, a custom sofa by KGBL, covered in a Holland and Sherry wool jacquard, and a "Tsunami" coffee table in heat treated steel and glass by Kin & Company. Additionally, a pair of vintage gio ponti stools, sculptural lounge chairs by Charles Kalpakian and Vladimir Kagan, and a custom wool and silk "Fracture" rug by Fernando Mastrangelo through Edward Fields accent the space.

In the main bedroom, silk and sisal wallcoverings join a custom bed designed by MKCA and a custom silk carpet designed by MKCA and made by Tai Ping. The draperies are made from a custom loomed textile in wool, silk, and mohair by Hiroko Takeda. And across the playroom, a hand-printed wallcovering and graphic carpet MKCA created with Stark Carpet complement a range of vibrant, modern furnishings from Moroso and Hem. 

Across the residence, each of MKCA’s architectural and interior interventions point back to the project’s original motivation: to transform the space into a fluid, elegant modern home while also making daring architectural and aesthetic choices. “From the very beginning, these were clients who asked us to take them outside of their comfort zone. The couple had very clear ideas about how they wanted to live, and how certain rooms should function, but were interested in an approach and an aesthetic that was more adventurous and expressive, but not kooky,” says Chen.

“To collaborate with clients who challenge us and who are willing to invest the time and energy into trying new things is really all we need to do our best work.”
