You could have called it the house that Disney built—except that little about this Mill Valley, California, home was magical when Cathy and Charlie Wilmoth bought it back in 2006. Believed to be a kit house built in 1955 by a Disney artist, the 2,265-square-foot, four-bedroom, three-bath home had devolved into something more worthy of Hitchcock. “There were army stickers everywhere, seafoam-green carpet in the bathrooms,” says Cathy, and a “fish tank” toilet seat with faux tropical fish suspended in acrylic.

Still, with three growing kids, then ages 2, 5, and 9, the Wilmoths were desperate for larger quarters, preferably mostly on one level. “Our old house was a 1906 cottage with ceilings so low I would stretch my hands overhead and hit the beams, and taking laundry and babies up the rickety stairs was a challenge,” says Cathy, whose schedule is busy with volunteer work and an office job at the local school. The property wasn’t anything like the 1920s Spanish house she and Charlie, an investment manager, thought they wanted; instead, it held things they didn’t even know they coveted. “I liked the Arizona sandstone fireplace and the windows and the heavy wood beams,” Cathy says.

It’s also atypical for Mill Valley, which is known for quaint cottages. “Mid-century kit houses were quite uncommon here,” says architect Pierluigi Serraino, author of NorCalMod: Icons of Northern California Modernism. “But construction companies would customize stock plans for their clients’ needs, and California was big on owner-built houses, especially by the late 1960s, when communities were developing their own aesthetic language.”

Serraino sees nods to Frank Lloyd Wright in the Wilmoth house’s canted-outward roofline fascia and stepped horizontal balcony, and to Walter Gropius in the vertical siding. “I don’t mean to be nostalgic, but so much of the later mid-century architecture isn’t quite as imaginative and daring. California was a definite trendsetter in 1950s home design.” Two issues buyers of kit-built houses need to be aware of, says Serraino: Those homes called for tailored engineering specific to the slope of the site, and they often have waterproofing issues.

The Wilmoth house, on a terraced parcel, had all the makings of a real estate Cinderella story until, four days after the family moved in, on a 106-degree day, something horrifying happened: They had a small electrical fire in the walls. “We were unpacking boxes and my husband came from the back of the house, asking, ‘Why aren’t the switches working?’ ” The fire department came, didn’t find anything, and left—but when Cathy put her hand on a wall and felt heat, the couple called them back. “They took an ax and broke through the redwood paneling in the living room—there were no junction boxes, everything was wired together with duct tape,” she says. “It was bad.” But ultimately it was also freeing: The fire forced the homeowners to upgrade all the electrical, which meant gutting the walls and removing the original paneling, which they donated to Habitat for Humanity.

Galley Kitchen Upgrade
“When you move into an old house, you think, What do we keep, and what can we get rid of?” Cathy explains. “We didn’t want to paint the redwood because it’s so beautiful, but it also felt dated and really dark.” With the walls open, the couple seized the opportunity to add overhead and cabinet lights, rare in houses of this vintage. They also repaired significant rot in the eaves, a continuing problem as the roof has no gutters.

Laundry with Skylight
Since the unexpected expenses ate up much of their available budget (they still hadn’t sold their previous house), the couple took the rest of the renovation slowly. Cathy had wanted to redo the kitchen, which had no working oven, soon after they moved in; instead, she cooked with a countertop convection oven for two years. But she’s now the first to say the wait ended up a blessing, fending off slapdash decisions they might have come to regret.

For one thing, she had longed to replace the carport outside their master bedroom with an expanded master bath. Having to wait proved a godsend when she injured her back and desperately needed easy access to her wheels. “The remodel forced us to sit in the house for a bit, which is really important. Even expanding the kitchen, something we wanted to do, would have been a mistake—it just wouldn’t have made sense with our rooflines.”

The early changes they did make were critical to their current love for the house, including painting the lofted wood ceilings—stained pinkish red—white. “I wanted it bright, because we’re in a canyon, and the light changes are extreme,” Cathy says. They also replaced original single-pane windows with triple-panes and tight-fitting trim. “That first year with the original windows was freezing,” Cathy recalls.

After several more years, finally ready to revamp the tired time-warp kitchen, master bedroom, and bath, the Wilmoths bit the bullet and hired a designer, Caitlin Moran. “She adores mid-century,” Cathy says. “Rather than rip everything out, she wanted to stay true to the house and make it better.”

Moran was thrilled to find homeowners who felt the same and had spent hours poring over Dwell magazine and houzz.com. “Cathy’s family loved the bones of the house, and weren’t trying to make it something it wasn’t, which was music to my ears,” she says. Moran infused each room she touched with finishes that reflect its California environs, like bleached-oak cabinetry and locally made clay tile.

“In the kitchen, we tried to maximize storage—Cathy cooks, and it’s also her laundry room—while being sensitive to mid-century lines with streamlined choices,” Moran says. “Because it’s visible from the dining and living rooms, the kitchen needed to feel like an updated version of what could have been there in the beginning.” Still, it gained conveniences a 1955 builder couldn’t have dreamed of—like a 3-gallon compost bin beneath a hole in the countertop.
In the master bath, Moran removed a closet in favor of double sinks, and laid herringbone marble floors with electric radiant heat. “Under-the-floor heat mats are a real life improver,” she says.

Count Cathy as a fan as well. “I walk out of this bathroom at night and get into bed with warm feet, which makes my husband happy,” she says.

But the biggest change in the bath was also the simplest: “When we moved in, the bath was open to the bedroom!” Cathy says. Adding a door put an end to that misguided moment in contemporary design.
Shown: The Wilmoths installed blackout shades over the skylight they added in the master bedroom, and a bank of wardrobe cabinets opposite the bed.
Hiring a designer is another decision Cathy more than endorses. “I feel like I saved money in the long run—I can’t tell you how many times I’ve repainted a room because I hated it,” Cathy says. “As a homeowner, you’re overwhelmed with choices.” Moran collected furnishings from both high-end and mainstream sources to great effect, and coaxed Cathy into unorthodox moves for reasons that make sense whether or not there are kids at home. For instance, the kitchen stools are upholstered in vinyl, “but you would never know—it’s beautiful, with a cool modern pattern,” Cathy says. “Someone spilled wine on a stool not long ago, and it wiped right off.”

A favorite space is the 12-by-10-foot outdoor room in back, with a gurgling stone fountain similar to ones their contractor, John Long, installed at Big Sur’s famous Post Ranch Inn. They added a gas fire pit nearby, which eliminates sparks in this recently wildfire-ravaged area. “While we were doing the kitchen we had access to the gas line, and we realized if we didn’t do it then, we’d have to tear up the floor later,” Cathy says. “We go out in the rain, we entertain there; anytime we have people over, this is the best room ever.”

Fire Pit Patio
Landscape designer Kier Holmes planted low-water plants with year-round interest to complement the house’s architecture—and stand up to the deer. In a nod to the man who built the house, the Wilmoths incorporated art pieces he made out of concrete and pebbles in the patio paving. “Now we love where we live. I have no complaints,” Cathy says, summing up. In other words? They all lived happily ever after.

Form and Foliage
Lush landscaping that relies on form and foliage, rather than flowers, softens up the home’s dramatically canted roofline.

The interior of the 2,265-square-foot house, built in 1955, stayed largely as it was, with a master suite, two bedrooms, and a second bath on the main level; on the lower level, interior walls were added to carve out another bedroom suite. In the kitchen, the sink moved to a window location, upper cabinets came out above the bar seating, and the fridge moved next to the laundry, which stayed where it was. The baths were all gut-renovated; the master bath lost a closet to gain a second sink.
