In this Mill Valley home, California light falls across herringbone floors, floral wallpaper has company in contemporary art, and an heirloom table looks perfectly at ease beneath sculptural lighting. The owner wanted a home that acknowledged her British roots while embracing the more relaxed sensibility of Northern California. Jennifer Tidwell, co-founder of The Workroom Interiors, found common ground in handsome woodwork, tactile fabrics and a generous helping of pattern.

'Our client wanted the house to feel like it belonged in California while nodding to her British heritage,' Jennifer explains. Working with architect Kelly Haegglund, Jennifer undertook a full-home renovation that balanced the owner’s love of bold color and pattern with the practicalities of life with two teenage boys. Furniture from the owner’s childhood helped shape the interiors, alongside a contemporary art collection curated in collaboration with British art consultant and friend Lucie Charkin, featuring works exclusively by women artists.

Step inside, and the owner’s British roots are immediately visible in the entry’s herringbone floors and wall moldings. Farrow & Ball’s ‘Drop Cloth’ creates a warm first impression, while a botanical photograph by Kija Lucas introduces the contemporary art collection that Jennifer worked into the scheme from the outset.

At the heart stands the owner’s round heirloom table. ‘She wanted her heirloom table to greet her guests, so it grounds the space in the center of the room,’ says Jennifer. A vintage Chiton chandelier and an Apparatus sconce share materials across different eras, showing how pairing vintage and contemporary pieces can feel cohesive without everything having to match.

The mudroom takes its cue from the British boot room. A built-in bench topped with a plaid cushion offers somewhere to sit and pull off boots, with handy hooks above and cabinetry for the belongings that tend to gather by the door. Painted woodwork and a patterned floor make this hardworking corner feel as thoughtfully dressed as the rooms beyond.

Two generous sofas face off across a low wood coffee table in the living room, setting up the space for conversation as naturally as the fireplace does for a chilly evening. Farrow & Ball’s ‘Shadow White’ walls and barely-there curtains leave the windows to frame the greenery outside; plaid and checked cushions bring a hint of British woollens and tailoring to the seating, their familiar geometry breaking up the plain upholstery without overwhelming the light-filled room.

Beside the fireplace, Halabala chairs reupholstered in indigo Anne Kirk Textiles fabric introduce sweeping wood curves to the arrangement. Cushioned built-ins make room for an extra perch, with cabinetry in Farrow & Ball's ‘Mouse’s Back’ adding depth. 'Mixing the old with the new in this home was really important, as it gives a home depth and provides a story of the people who live there,' Jennifer says.

The dining room has a particularly good conversation starter overhead: a Trueing chandelier whose glass links loop above the wood table. Chosen early to anchor the adjoining spaces, it sets a more adventurous, ‘edgy and cool’ tone than the traditional woodwork might suggest.

An Allison Gildersleeve painting supplies an equally spirited backdrop. The collection features contemporary female artists, with some works chosen before their rooms were designed. Deep purple in this painting found its way into the Zak + Fox upholstery on Lawson-Fenning chairs. Everything around it is restrained enough to let the artwork have the floor.

The kitchen borrows the familiarity of English cabinetry and gives it room to breathe. Cabinets painted Farrow & Ball's ‘Light Gray’ frame a walnut island, while Calacatta Borghini marble introduces flowing veins among the orderly panels. Burnished-brass Modern Matter hardware adds a little polish; deVOL Creamware pendants keep the lighting pleasingly simple.

'Our cabinetry molding detail was inspired by deVOL,' Jennifer explains. In the pantry, Abigail Borg's ‘Muscari Coal Ecru’ wallpaper and diagonally laid black-and-white stone flooring give everyday storage an unexpectedly decorative setting.

In the family room, nods to British tailoring transition to the walls, with tweed-like herringbone wallpaper and a tartan ottoman framed by oak woodwork. Oak windows, crown molding, and cabinetry distinguish it from the paler rooms, with Phillip Jeffries' ‘Ireland's Eye’ wallcovering adding the texture of tweed. Farrow & Ball's ‘London Stone’ continues the warmth (and British theme) across the ceiling.

'We wanted the room to feel transformative right when you entered,' says Jennifer. A broad ottoman in Holland & Sherry's ‘Sona Tartan’ occupies the middle of the seating group, its generous proportions inviting feet up. Smaller hassocks keep the arrangement flexible.

The study holds the key to the home's color scheme. Madeaux's ‘Samarkand’ wallpaper in Mole fills the walls with expressive pattern, surrounded by cabinetry, trim, and a ceiling painted Farrow & Ball's ‘Brinjal’. Walnut shelves and counters bring a warm wood note to this richly layered workspace.

The owner fell for the Madeaux wallpaper's colors and contemporary pattern early in the project. 'It became the color story to pull from throughout,' Jennifer recalls. The study’s concentrated palette supplied colors to revisit elsewhere, helping rooms with very different patterns feel connected.

The primary bedroom lowers the volume with Farrow & Ball's ‘Charleston Gray’, carried across walls, trim and the wood-plank ceiling. Keeping the overhead surface in the same color makes the room feel enveloping, while broad windows prevent the scheme from becoming heavy. A patterned throw and textured pillows give the bed the layered feel of a well-stocked linen cupboard, with the upholstered headboard adding another tactile note. Workstead sconces with linen shades and a Lawson-Fenning pendant add warm brass, and a wood nightstand with a scalloped apron completes the room.

The primary bathroom carries the bedroom’s interest in textiles onto the walls. FAYCE’s Lapel grasscloth has the finely drawn geometry of a tailored fabric, paired with ribbed walnut vanity fronts that introduce another layer of texture. Calacatta Oro marble provides a smoother counterpoint, while round brass-framed mirrors and small globe sconces soften the angular pattern.

The first of the boys’ rooms gives stripes and checks a lively, blue-led palette. A wood-framed headboard with striped upholstery and small embroidered crosses sits behind fine checked bedding, a broader plaid throw, and a striped accent pillow. The changes in scale make the mix work. Farrow & Ball's ‘Light Gray’ supplies a calm backdrop, with Benjamin Moore's ‘Hale Navy’ deepening the cabinetry. Lostine sconces bring black leather into the scheme, and above the bed, a landscape artwork brings a wilder geometry to the room, its rugged ridgelines contrasting with the orderly checks and stripes below.

In the second boy’s room, green and ochre plaid picks up the warmth of Farrow & Ball's ‘Stony Ground’. A sloping plank ceiling and vertical boards behind the bed give the space architectural texture, while built-in storage fits neatly beneath the roofline. An oak ledge above the upholstered headboard provides a useful perch without crowding the bed. A pale bench with dark straps repeats the room's mix of softness and crisp detail, and a brass-and-black wall light adds definition against the light woodwork.

Morris & Co.’s ‘Marigold’ wallpaper in Bullrush gives the guest bathroom an unmistakable English decorating reference. Its intricate foliage surrounds an oak vanity topped with Calacatta Oro marble, with an oval mirror and ceramic-shaded sconce lending gentler curves to the compact arrangement.

‘Our client really thought through every detail, and she embraced the design process from start to finish,’ says Jennifer. The result makes a persuasive case for taking stock before starting afresh: a favorite chair might need new upholstery, an inherited table a different setting. It is a useful reminder that the starting point for a beautiful room may already be in your possession.
