Where Sustainable Luxury Meets California Cool

The Cardiff House is located in the beach community of Cardiff-by-the-Sea, Calif., a coastal gem nestled between Solana Beach and Encinitas in northern San Diego County. Soheil Nakhshab, the owner of the property, has a passion for surfing and the outdoors, so naturally, the neighborhood was a perfect fit. His chosen parcel is a perfectly flat plot of land that allowed him to create the perfect indoor-outdoor living spaces he envisioned, a back courtyard jewel perfect for entertaining, exercising and unwinding.

About the Builder

For Nakhshab, family is everything. Together with his younger brother and father, the trio have helped countless families build their dream homes since founding Nakhshab Development & Design in 2003. The award-winning firm strives not only to design and build better homes but to curate better lifestyles, drawing on more than 50 years of experience across architecture, development, engineering, construction and design, with roots reaching back to Iran.

Their building philosophy revolves around what they describe as the “master-builder” tradition, unifying architecture, engineering, construction and interior design under one accountable source to create cohesive, efficient and human-centered environments. Nakhshab emphasizes harvesting the energy of a site and the client’s needs to shape homes that are beautiful, welcoming, sustainable and unique. They prioritize craftsmanship, collaboration and sustainability, integrating natural light, site characteristics and thoughtful design strategies to enrich everyday living experiences.

The Importance of Place

The neighborhood itself has transformed over the years from coastal farmland and beach cottages into an area of highly desirable, multimillion-dollar homes, with prices shaped by proximity to the coast, privacy, views and modern architectural features.

Outdoor zones include a pool courtyard, covered living space and a crescent moon-shaped raised planter that separates the pool from the rear yard. This moon shape is also the designer’s logo signature. NDD’s signature feature for nearly 20 years has been custom concrete fireplaces wrapped in steel and set on lava rock sand. The steel enhances heat radiation from the gas flame, while the sand softens the sound of the gas, creating both a visual and functional centerpiece.

The Cardiff House accommodates the needs of everyday life, including designated work-from-home spaces, and entertainment spaces. The community evokes Southern California with easy access to trails, the beach and a quaint community center; an adjacent public park adds to the family-friendly vibe.

Building Sustainably

NDD has become synonymous with sustainable design. More than 90% of their properties achieve LEED certification status. Other specialties include reviving historical properties, navigating tricky urban infill sites and conquering steep parcels while designing to enhance everyday living.

As part of their sustainable building practice, they incorporate native flora, partnering with landscape contractor Chip Lievers of LLM Landscaping, who executed the landscape installation.

In addition to solar panels, the house is equipped with three 4,000-gallon rainwater harvesting tanks connected directly to the site irrigation system. Less water is needed to maintain the landscaping, and the ecosystem is largely self-sustaining. The rainwater tanks support fruit trees, plants and raised garden beds filled with fresh vegetables.

The sustainable qualities of the home are evident in the building materials: natural wood, stone, steel and glass. Local craftsmen fabricated finishes, supporting the local economy and maintaining a sustainable footprint.

Designing on a flat lot presents a unique challenge, as the lack of topographical influence gives the architect total freedom. With neighboring homes to the north and south, privacy became a priority, prompting a U-shaped footprint that encloses an interior courtyard.

Despite the challenges, the Cardiff House was a collaborative effort. Architect and developer Soheil Nakhshab led the vision, integrating architecture, landscape and engineering to respond thoughtfully to the site.

Soheil Nakhshab worked alongside LLM Landscaping to craft a serene environment. Metal fabricator Jason Spakes executed custom steel work, while interior designer Sheiva Brunst guided interior selections to create a curated yet personal home. Custom cabinetry by Ivan Ramos completed the architectural language, resulting in a cohesive living experience by the sea.
