Influenced by the California lifestyle, Terri Brien Interiors designs warm, character filled spaces with thoughtful detail and a curated mix of new and storied elements.

As a full-service boutique interior design firm nestled in the heart of Southern California, Terri Brien Interiors creates bespoke  elevated, livable environments shaped by thoughtful detail and expert guidance. We believe a home should reflect the people who live there through meaningful design choices, curated layers, and a lived expression of personal style.

Our approach blends timeless materials, modern sensibilities, and pieces with character and heart. Through considered composition and a discerning eye for sourcing, we design spaces that feel curated and collected rather than simply decorated. Every texture, finish, and form has intention behind it, contributing to the depth and personality of the home.

We pay attention to the details that matter most. From ensuring your coffee table is the right height for your sofa to layering tactile materials that invite touch and visual interest, we design with purpose and a holistic view of how the space will be lived in.

With decades of experience and a process rooted in clarity, we guide clients through each decision with confidence. From planning to installation, we anticipate needs ahead and streamline the path to completion. The result is a home that feels elevated yet effortless, beautifully aligned with how you live today and adaptable to the life you continue to build.
