Peter Pennoyer and Katie Ridder Take to the Country


The new book A House in the Country (Vendome) by architect Peter Pennoyer and interior design Katie Ridder (above) — together with coauthor Anne Walker — chronicles the couple’s design for their home in Upstate New York’s Millbrook (top), which blends traditional and modern elements, both inside and out.

Peter Pennoyer and Katie Ridder are, in their very understated way, a power couple on New York’s design scene. Pennoyer and his eponymous firm are best known for creating traditional but never stuffy houses, such as the Adirondacks retreat inspired by Swedish vernacular architecture they built for the late lawyer and writer Louis Auchincloss. For Pennoyer, classicism is “a living language,” not something to be slavishly copied, but rather “reshaped to make architecture that is comfortable for the way we live today.” Ridder’s interiors, meanwhile, characterized by a deft blend of traditional and contemporary furnishings and confident use of color, range from gracious Manhattan apartments to houses in Maine and California. The two share an office on lower Madison Avenue and have collaborated on many projects, although they don’t always work together.

Because of their substantial talents and unique point of view, when the couple — after years of looking for just the right spot — decided to design a weekend house for themselves and their three children in Millbrook, New York, the results were positively enchanting. A seamless union of Pennoyer’s elegant Greek Revival architecture and Ridder’s sophisticated, comfortable interiors (she also designed the extensive gardens), the house offers a fascinating look at how two people with distinct design outlooks can weave them into a coherent whole. This process is eloquently chronicled in A House in the Country (The Vendome Press), the recently released book the couple wrote with Anne Walker, Pennoyer’s co-author on four volumes about early 20th-century architects; the seductive photographs are by Eric Piasecki.

The couple met in 1987 when Ridder, then an assistant at HG (Anna Wintour’s revamp of House & Garden) was working on a story about one of Pennoyer’s projects. They married the following year, combining their lives — and their disparate aesthetics. A product of New York’s Upper East Side and Columbia University, Pennoyer had designed his own apartment as an exercise in classicism, handsome if somewhat somber. Ridder lived a few blocks away, but in another world, one of light, color and pattern. She’d studied art history at USC and loved to make things (the book features a quilted fish-shaped pillow she made as a teenager), showing off an eclectic sensibility that would serve her well at the wide-ranging home store the couple went on to own in Manhattan in the 1990s, before she became a decorator herself. In their first apartment, she painted one wall of the living room a vivid blue to set off an array of framed artworks. He was in charge of the guest bedroom’s decor, which comprised correct, American Empire furniture. In time, however, as Pennoyer explains in the book, “[w]e found that our essentially different tastes inspired rather than limited our design ideas. We were at our most open and imaginative when working together.”

“Although the process was not without drama, none of it came from within our marriage,” Pennoyer writes of the couple’s experience creating their country house together.

The classical idiom of the home’s architecture is combined with a contemporary open plan on the first floor, where the dining room opens to the kitchen. Printed-linen portieres provide privacy for dinner parties (and prevented Pennoyer’s having to design large doors that would get in the way of furniture). The couple found the Regency-style black lacquer and cane chairs at an auction.

To be sure, their expansive 1920s house in the New York suburb of Bronxville, just north of Manhattan, offered the couple the opportunity to collaborate with and inspire each other, but the house in Millbrook gave them the chance to create something all their own from the ground up. To some, this might seem a surefire recipe for marital discord, but not for these two: “Although the process was not without drama, none of it came from within our marriage,” Pennoyer says.

Set on six and a half acres surrounded by farmland, the two-story, four-bedroom house, whose architecture is by Pennoyer and Gregory Gilmartin, his firm’s director of design, has four different facades. The west one, with fluted Doric columns flanking the front door, is the most formal, while the north one’s semicircular bay is adorned with bas-relief depictions of a dog — the family dachshund, Teddy — chasing a rabbit. Regardless of which facade you’re looking at, what strikes you about the house is the intimacy of its scale and how lightly it wears its architectural erudition.

This is also true of the house’s interiors, a brilliant hybrid of traditional and modern that could only be achieved by the synergy of Ridder and Pennoyer’s very different approaches to design. The architectural vocabulary is clearly classical, but the first floor is emphatically open plan, its main rooms (except the study) devoid of doors, allowing the spaces to flow freely into one another, sharing views and daylight. The rooms are relatively small, but their generous proportions and tall windows make them feel grand and cozy at the same time. There are also some especially contemporary touches: The house employs state-of-the-art energy-efficiency technologies, such as radiant-heated floors, and a 3-D printer in Pennoyer’s office produced the models for the home’s traditional hardware.

In the couple’s spirit of give-and-take, it was Ridder who asked Pennoyer for 12-foot ceilings, and it was he who suggested that she design portieres for the living- and dining-room doorways. Her assent spared Pennoyer “the awkwardness of having to design huge doors that would swing into the rooms and make it harder to place the furniture,” he says. Her reply: “It’s really nice how you think of these things; not all architects do.”

The antique Oushak carpet in the brightly hued living room once belonged to San Francisco arbiter of style Dodie Rosekrans, a contributing editor at House & Garden when Ridder worked there. The couple found it at auction, and it became the first thing they bought for the house. The room’s color scheme plays off the rug’s palette, while the mantel is based on a design by John Soane.

Each of the house’s four facades has a different look and feel, with the bas-reliefs set into the semicircular bay of the north elevation whimsically depicting the couple’s dachshund, Teddy, chasing a rabbit.

Ridder designed not only the house’s interiors but also the gardens on its six and a half acres. Here, Pennoyer created a pergola as an outdoor dining room, one whose minimalist appearance wouldn’t distract from his wife’s vibrant beds of perennials and various specimen plantings.

Left: Pennoyer laid out the bright off-white, light-filled kitchen with a breakfast area, seen here, on one side of an island and the cooking area on the other. Right: In an homage to a tented bedroom at Charlottenhof Palace, in Potsdam, Germany, Ridder covered the walls of the bedroom of the couple’s daughter Gigi in a striped linen trimmed with red grosgrain ribbon. The chair is upholstered in a linen Swedish print, while the painting above the desk, Forms of Trees and Clouds, is by modernist Karl Schrag.


Ridder’s cutting garden sits behind a barn and in front of the cornfields of a neighboring farm. In these elevated beds, she grows dahlias — 80 different types—peonies, cosmos, zinnias, sunflowers and other annuals, as well as vegetables, herbs and berries.

Left: Ridder covered the walls of the stair hall in a French blue wallpaper of her own design. Called Scraffito, it takes its name from, and also recalls, an ancient method of decorating building facades. Right: In the bathroom of the master suite, a simple marble double vanity and mirrored medicine cabinets form a subtle counterpoint to the yellow walls and the orange rug, a tribal piece from Morocco.

Pennoyer set the master suite’s bed in a niche, flanking it with recessed walnut nightstands of his own design. Ridder’s color scheme refers to the turn-of-the-20th-century Donegal carpet on the floor.

Left: A small vestibule connects the entrance hall and the study, also providing access to a powder room and a coat closet. Right: For the study — the only room on the open-plan ground floor that can be closed off from the others — Ridder selected a wool tartan for the armchair and edged the fern-green sofa with caterpillar trim. The linen curtains are from Swedish textile designer Jobs Handtryck.

“Each of us gave the other space,” writes Pennoyer in the book’s introduction, describing the couple’s successful collaboration. “Katie trusted my team and me on the architecture, and I trusted her and her team on the decoration and garden.”



“Purple tiles are not the way my mind works,” Pennoyer says of his wife’s design for the home’s front hall. “I would never have gotten there in a million years.”

Ridder uses intense color in these rooms to captivating effect: the deep pink velvet of the living room sofa against the paler pink tea paper on the walls and the ochre and red Oushak rug; the contrast between the dining room’s mulberry lacquer walls and the yellow of the curtains. Richly patterned fabrics and wallpapers, some of them Ridder’s own designs, offer proof that in the right hands, more really is more. “It’s much more layered than what I do with clients,” she says.

Perhaps the room that best illustrates the couple’s creative exchange is the front hall, where a marble bust of Abraham Lincoln on a wooden pedestal (him) stands on a floor of Moroccan tiles glazed in various shades of purple (her). “Purple tiles are not the way my mind works,” Pennoyer admits. “I would never have gotten there in a million years.”

The couple’s passion for design has filtered down to the next generation. Their oldest child, Jane, 23, works for the interior designer Martyn Lawrence Bullard and also customizes Superga sneakers with applied vintage fabrics. “She has the same craft obsession I do,” Ridder says. Son Tony, 21, a film major at the University of Michigan, specified his room’s red and blue color scheme and vetoed the photographs his parents chose for the space. Younger daughter Gigi, 16, is also showing interest in aesthetics: “I can see her working for me one day,” her mother says.

Pennoyer’s current projects include the recently completed brick-and-limestone apartment building at 151 East 78th Street in Manhattan; a Czech Cubist–influenced house near Cleveland, for a collector of art and design; a new house on a historic street in Newport, Rhode Island; and a line of hardware for Lowe that includes Cubist pieces inspired by the aforementioned collector’s house. Ridder is at work on the interiors of houses in Greenwich, Connecticut, and L.A.’s Hancock Park neighborhood. She has also taken on the decoration of a carriage house in Bridgehampton, on the east end of New York’s Long Island, that her husband designed for a client with “a great art collection, who loves color as much as I do,” she says.

Having collaborated successfully on a house of their own, would they ever consider doing it again? “In a heartbeat,” Pennoyer says without hesitation. Adds Ridder: “I love the ocean” — perhaps a clue to the type of spot where the couple will next work their collective magic on a place they’ll call home.

“The combination of brass, blown glass and the laurel-berry motif creates an interesting dynamic between the man-made and nature,” says Ridder.

“Among Swedish furniture designers I admire, Malmsten stands out for the delicacy of line in his work,” Pennoyer says. “The compound curves in this cabinet make it feel almost Baroque, while the floral inlay is wonderfully subtle.”

“This piece is both timeless and practical,” says Ridder. “Folding furniture has stayed in the design canon for centuries, not only because of its usefulness but also because its form dates as far back as ancient Egypt.”

“This table combines rosewood veneer, tulipwood, mirror, marble, giltwood and bronze to make one exquisite object,” says Pennoyer. “The combination of materials and design elements is masterful and makes a piece of furniture that is fully architectural.”

“I like the large scale of the elliptical grilles in the bookcase doors,” explains Ridder. “The satinwood and mahogany are elegant, and the piece has a lot of presence, considering that it’s only fourteen inches deep.”

“I am taken by the primitive, sensual bud-like pattern on this vase. Here, Salto has used form to display the depth and character of the glaze in a way that reminds me of great Japanese ceramics,” says Pennoyer.

“I love the classic shape of this chair, and the updated upholstery makes it feel uniquely modern,” says Ridder.

For Pennoyer, “the magic of Dunand’s vases are the added dimension he achieved through his uncanny sense of color and pattern. In this screen, he marshalled these skills to create an utterly magical scene where the woods recede into deep perspective.”
