Today’s investment landscape in California features a surge in transforming single-family lots into vibrant multi-family residences, facilitated by recent SB9 and ADU laws. This project exemplifies how a modest 6,750-square-foot lot can accommodate a 1,500-square-foot primary home alongside a 2,500-square-foot duplex, seamlessly integrating design, functionality, and neighborhood aesthetics. The primary residence underwent a meticulous interior transformation, evolving from a 3-bedroom, 1.5-bath layout into a spacious 4-bedroom, 2-bath home. Strategic reconfigurations centered around creating an expansive great room—an open-concept space adorned with vaulted ceilings—where the kitchen, dining, and living areas converge into a magnificent communal zone. Exterior updates further distinguish the property. The front and side yards are enclosed with fencing and privacy hedges, linked by concrete pathways that enhance outdoor functionality while compensating for backyard space lost during renovations. The exterior façade was refreshed with darker tones, deliberately contrasting with the duplex to emphasize architectural separation. Designed to preserve the suburban charm, the duplex visually mimics a single-family home from the street. Its facade creates an illusion of a two-story residence, maintaining harmony within the neighborhood fabric. The main unit, developed under SB9 guidelines, features three bedrooms and two bathrooms, with a luxurious parents’ suite situated upstairs. Downstairs, two bedrooms share a full bath, creating a balanced family-oriented layout. The duplex’s interior boasts 9-foot ceilings throughout, elevating the sense of space and openness. The design thoughtfully places the kitchen at the front, inviting guests into the home, while stairs on the right lead to the private upstairs bedroom suite. The ADU offers a two bedroom and two & half baths. the unit is accessible via a private side entrance with a dedicated walkway. Its layout includes a ground-floor living room, a galley kitchen, and a discreet powder room beneath the stairs, designed to contain guest traffic and maintain privacy upstairs. The upstairs bedrooms each feature luxurious bathrooms with expansive showers, adding an element of modern elegance. Both units enjoy thoughtfully landscaped outdoor spaces—private patios, backyard areas, and gated front yards—creating welcoming environments for residents and visitors alike. This project exemplifies innovative urban infill solutions, blending architectural elegance with legal compliance and community harmony—an inspiring blueprint for the future of residential development in California.

the Iris is a three-bedroom home that offers enormous flexibility in design alongside cottage comfort and charm. In true cottage-style fashion, a large front porch provides a warm welcome to neighbors and friends and also serves as a great spot to relax and unwind at the beginning or end of a day.

This walk-in butler's pantry and bar is a study in thoughtful storage and everyday luxury. Custom floating wood shelves display an edited collection of wines and spirits alongside a dedicated dual-zone wine and beverage refrigerator finished in a warm bronze tone, its glass-front doors offering a curated glimpse of the bottles within. Crisp white cabinetry and countertops keep the space bright and functional, providing a dedicated prep station for the KitchenAid mixer, coffee maker, and toaster, while rich oak flooring grounds the room in natural warmth. It's a space designed for both daily rhythm and easy entertaining — organized, elevated, and unmistakably livable.

Built for the Bluff, A Sea Ranch Home is Remade from the Inside Out The house had always been grounded, on an ocean bluff at The Sea Ranch. It sits unencumbered, adjacent to one of the most dramatic stretches of the Sonoma coast with protected commons meadow to the east, uninterrupted Pacific views to the west, and a bluff trail running alongside. What it lacked was the feeling of home, one that could hold up its own against the natural landscape. The owners are entrepreneurs with deep involvement across tech, real estate, and development and they know how things are built. The Sea Ranch house had been in their lives for years, a second residence and a place for family to gather. Built for a different time, it felt more compromising than comfortable. Sitting in a closed off nook, the kitchen fit one cook at a time and turned its back on the rest of the house. The entry was dim and compressed, divided by a structural column that presented itself at exactly the wrong moment. The primary suite was small relative to the view outside it. A large rear bedroom sat behind a lowered ceiling with a bathroom that had never been added. The house was certainly worth the trouble of doing it right. What followed was not one project but four, each with its own design challenge, each addressed over a period of time. Where the House Meets the Ocean The most complex piece of the project, in both structural and spatial terms, was the kitchen expansion. The existing room was a single-person galley squeezed in as an afterthought with no meaningful connection to the dining room, the living space, or the deck outside. To make it useful for a family that cooks and gathers, it needed to grow outward into an existing patio and flow into the rooms around it. A big challenge was the roofline. Several planes at different pitches and angles converged directly where additional volume was needed. A new form had to join that geometry without reading as a correction. The solution found the simplest possible connection between the existing angles, a roofline that from outside the structure, appears entirely original. From the bluff trail where the addition is visible, there is no discernible seam. Inside, the kitchen is now open to the living and dining rooms without interruption. A large sliding glass door connects the space onto the rear deck. The deck itself was expanded and oriented so that the body of the house shields it from the coastal wind which is a common consideration that determines whether outdoor space at The Sea Ranch actually gets used. The result is a room that works for large family gatherings where no one feels cutoff, and one that makes the boundary between being inside and outside easy to ignore. Welcoming Light A structural column stood at the convergence of eight distinct roof planes in the entry. It was load-bearing, but it was also the reason the entry had always felt like a hallway rather than a welcoming arrival. With the structural engineer, a custom steel connector was designed to receive beams from six separate directions, redistributing the load through a single new continuous beam. The column was surgically removed. Three triangular skylights were then cut into the roof above, their shapes drawn from the existing geometry of the planes around them. The entry is now bright and open. The skylights feel native to the structure because they follow the logic already present in the roof. Two Suites, Two Views At opposite ends of the house, the two bedroom suites were each reconfigured, and each found a different way to introduce more of the landscape into the room. An addition to the primary suite extended the structure outward to create a wraparound plan with a loop from the bedroom through bath and closet that had not been possible before. The expansion opened a slot view from the tub and shower toward the ocean. The view is precise and private. The ocean view is present and deliberate. The rear bedroom absorbed an adjacent storage room to transform it into a full second suite with a vaulted ceiling, a large bathroom with a tub, a shower, and a sauna. A private fenced garden courtyard sits just beyond the glass bringing the outdoors inside. The tub was placed so that, looking past the courtyard and through the bedroom beyond, the ocean is visible at the far end. It is a long view and it makes the room feel larger and more settled than its footprint would suggest. Glass on Four Sides, Fire at the Center The main living and gathering room had always been caught between two competing facts: glass on four sides meant exceptional views but at The Sea Ranch, it also meant a cold room. A 360-degree cylindrical fireplace was added at the center on a raised stone base, providing radiant heat in every direction and giving the room a focal point around which a group naturally orients itself, whether that means two people at the end of the day or the whole family after dinner. Owners Who Picked Up the Tools The owner was not a passive client. they came with construction knowledge, specific ideas, and the desire to be an active part of the process, a dynamic that other architects may had found difficult, which Klopf Architecture accepted as an asset. They took it upon themselves to complete some of the work during construction, including the installation of a new radiant heating system beneath the floors. The radiant system added to the older and less-desirable forced-air setup. At The Sea Ranch, that change matters as the house sits close enough to the ocean and moving air competes with the sound of it, where radiant heat does not. Solar panels were added to the roof as part of the new system. Insulation was upgraded throughout the walls, roof, and crawl space. The house that had always had the right setting now holds warmth the way a house on the bluff should. They were also deeply involved in the design and selections throughout, and the finished house reflects both of them in ways that are specific rather than generic. The process took longer and moved through more iterations than a more arms-length relationship might have allowed. The result is more defined and personal because of it. The Landscape Holds Priority Every exterior decision was shaped by The Sea Ranch Design Standards, which require that buildings defer to the landscape around them rather than compete with it. Because this house sits on the bluff and is visible from the public trail, the additions faced a close review. Existing materials were matched. Geometries were resolved. The additions had to become indistinguishable from the original building. From the trail, the house reads exactly as it always has — low, cedar-clad, secondary to the meadow and the water. The setting holds priority. Inside, the house has been remade. Klopf Architecture Project Team: Geoff Campen and Trenton Jewett

Its facade creates an illusion of a two-story residence, maintaining harmony within the neighborhood fabric. The main unit, developed under SB9 guidelines, features three bedrooms and two bathrooms, with a luxurious parents’ suite situated upstairs. Downstairs, two bedrooms share a full bath, creating a balanced family-oriented layout. The duplex’s interior boasts 9-foot ceilings throughout, elevating the sense of space and openness. The design thoughtfully places the kitchen at the front, inviting guests into the home, while stairs on the right lead to the private upstairs bedroom suite. The ADU offers a two bedroom and two & half baths. the unit is accessible via a private side entrance with a dedicated walkway. Its layout includes a ground-floor living room, a galley kitchen, and a discreet powder room beneath the stairs, designed to contain guest traffic and maintain privacy upstairs. The upstairs bedrooms each feature luxurious bathrooms with expansive showers, adding an element of modern elegance. Both units enjoy thoughtfully landscaped outdoor spaces—private patios, backyard areas, and gated front yards—creating welcoming environments for residents and visitors alike. This project exemplifies innovative urban infill solutions, blending architectural elegance with legal compliance and community harmony—an inspiring blueprint for the future of residential development in California.

Today’s investment landscape in California features a surge in transforming single-family lots into vibrant multi-family residences, facilitated by recent SB9 and ADU laws. This project exemplifies how a modest 6,750-square-foot lot can accommodate a 1,500-square-foot primary home alongside a 2,500-square-foot duplex, seamlessly integrating design, functionality, and neighborhood aesthetics. The primary residence underwent a meticulous interior transformation, evolving from a 3-bedroom, 1.5-bath layout into a spacious 4-bedroom, 2-bath home. Strategic reconfigurations centered around creating an expansive great room—an open-concept space adorned with vaulted ceilings—where the kitchen, dining, and living areas converge into a magnificent communal zone. Exterior updates further distinguish the property. The front and side yards are enclosed with fencing and privacy hedges, linked by concrete pathways that enhance outdoor functionality while compensating for backyard space lost during renovations.
