Full Service Design for New Home Builds

Designing a home from the ground up presents a rare and rewarding opportunity—to shape every detail with intention. At Stefani Stein Inc., we specialize in interior design for new home construction, guiding clients through a full-service process that begins long before walls are raised. From early planning and architectural coordination to finish selections and final styling, we ensure that every element supports a cohesive vision, crafted to reflect how you live and what you love.

 

We have extensive expertise in working with homeowners who are looking to design and develop new home construction plans. We participate in the project from the outset, engaging with clients during the early planning and discovery stages of their new home development. ​

Full-Service Interior Design for Custom Homes

New home construction offers a clean slate—and with it, a multitude of decisions. Our approach provides clients with clarity, creativity, and confidence throughout the journey. As a full-service interior design studio, we work collaboratively with architects, builders, and fabricators from the initial design concept through final installation.

Whether you’re building a primary residence or a vacation home, we ensure each space is both highly functional and beautifully tailored, seamlessly integrating interior architecture with thoughtful finishes and styling.

Why Hire an Interior Designer for New Construction?

Designing a new home involves more than choosing finishes or furnishings—it’s about shaping the way a space feels, flows, and functions. Engaging an interior designer early in the construction process helps to establish a cohesive design vision, avoid costly missteps, and reduce decision fatigue.

We often begin working with clients during the initial phases of discovery and development. This early involvement allows us to help clarify your aesthetic preferences, guide material selections, and ensure architectural elements support the overall mood and functionality you envision.

Seamless Collaboration with Your Build Team

Our role is not siloed. We function as an integral part of the larger project team, working closely with architects, general contractors, and specialty trades. During the construction administration phase, we provide design oversight and site coordination to ensure that the original vision is brought to life with precision and quality.

Because we engage with both the big picture and the smallest of details, we bridge the gap between structural planning and interior experience, ensuring the home is not only well-built, but beautifully lived in.

A Process Grounded in Personalization & Precision

In our studio, every new construction project begins with listening. We take time to understand how you want to live in your home—what brings you comfort, what inspires you, and how you want each space to feel.

With that foundation in place, we:

  • Collaborate with your architect on space planning and design direction

  • Provide guidance on interior flow, natural light, and room proportions

  • Prepare detailed interior elevations and millwork drawings

  • Specify custom cabinetry, lighting, hardware, and plumbing fixtures

  • Select finishes, paint colors, stone, tile, flooring, and appliances

  • Oversee styling, furnishings, and final layer curation

We act as your design advocate throughout the process, ensuring each choice contributes to a unified, elevated result.

Timeless Interiors, Designed to Endure

While we are based in Los Angeles, our interior design studio works on custom home projects throughout California and across the U.S. Our work often combines classic influences with modern living, blending nuanced palettes, rich materials, and functional elegance.

Whether designing for hillside homes, coastal retreats, or city residences, our interiors reflect a balance of authenticity, comfort, and refinement—spaces made to evolve with you over time.

Recognition & Editorial Features

Since launching in 2015, Stefani Stein Inc. has been recognized for its distinctive approach to interior design. Our projects have been featured in Architectural Digest, Elle Decor Spain, Home & Garden UK, AD Italia, The Wall Street Journal, and more.
