When California was wild, it was the most flower-filled part of the continent, said the naturalist John Muir, whose name graces a primeval redwood forest that lies just north of San Francisco and west of an old home that now blooms for a young family. Like the California of yesteryear, this Mill Valley house is also awash in florals—specifically in the form of pattern, put there by the hand of decorator Heidi Caillier, who cultivated this space to be native to both its new owners (a pair of Marin County natives with three young children) and its locale. “While I could say that our style is Americana, Shaker, modern traditional, warm, collected, or even farmhouse, I’d really prefer a home that is simply ‘of Mill Valley,’” the client initially told Caillier. Settled (and named) for the first sawmill in the region, the area saw a boom of vacation residences just before the turn of the 20th century.
This particular house was created as a fishing retreat in 1896, its walls insulated with pages of the San Francisco Chronicle. It’s the stuff of dreams for Caillier: The Seattle designer’s work is long on nostalgia, real or created; her rooms have a storybook quality to them that’s not about quaintness, but an out-of-time wholesomeness. In these spaces, you might feel a twinge of hesitance to pick up your phone, as if this world has better plans in mind for you.
“There’s something soft and gentle about this project since the homeowner is a very nostalgic person, as am I,” explains Caillier (pronounced KAL-ee-yer). “We wanted it a tiny bit sweet, but also a little bit rustic, like it had been there forever, with everything a little bit wonky and not pristine.” It starts with the architecture, she says. “A good builder will home in on details right down to the eighth of an inch, but I’m constantly saying, it doesn’t have to be perfect—life isn’t perfect!” Here, sconces are slightly askew, and the bamboo chik blinds hang a teensy bit lopsided. The looseness lets life in. “That’s the thing about creating imperfection,” says Caillier. “It’s very intentional.”
Caillier conjured a treehouse vibe in the primary bedroom, which is swathed in Light Blue by Farrow & Ball. The Hollywood at Home bed is dressed in D. Porthault sheets with a blanket by A Little Weather. The Cisco Home sofa is covered in a Penny Morrison fabric; Samarkand shades top the Penny Morrison lamps.

That cadre of charmers made quick work of plucking this house from the 2020s and placing it in a hazy, romantic past. Would-be froufrou details like a ruffle-skirted sofa or scalloped lampshades work here because Caillier keeps things balanced at every turn. In the inky mallard blue family room, the color drenching, muscular George Smith chairs, and rustic jute rug prevent sweetness from turning saccharine. Upstairs in the pretty, plaster-pink primary bathroom, old limestone floors and a vintage wood stool keep the scheme “from going over a cliff,” says the designer.
The guesthouse engendered no such fears. The 600-square-foot space joins the main house via a central corridor but is independent enough to exercise its own personality. Beautifully, it was right there for the taking. Early conversations unearthed a strain of Sea Ranch style, named after the 1960s Northern California coastal community known for its pared-back, barefoot-modern, cedar-clad houses. The concept seduced both client and designer, becoming the ideal jumping-off point for the cottage’s aesthetic. “It was one of those moments that took off right away,” says Caillier. “No hesitations!”
Tapping into the realm of NorCal hippie-modern, Caillier created a pert box lined with white oak, a few Danish modern furnishings, natural linen and burlap, and lighting by Commune. A thread of the living room’s deep blue winds through, offering a reminder that the ocean is a mere 10 miles away. Still, the story here is rooted in wood. It’s Mill Valley, after all.
