Influenced by the California lifestyle, Terri Brien Interiors focuses on creating comforting and curated spaces through the blending of new, timeless vintage and hand-crafted elements.

As a full-service boutique interior design firm nestled in the heart of Southern California, Terri Brien Interiors curates bespoke environments that epitomize sophistication, warmth, and elevated comfort. We believe a home should be a true reflection of the people who live there—effortlessly refined, undeniably inviting, and layered with meaning.

Our design philosophy embraces a timeless aesthetic, blending natural textures, storied finds, and bespoke details that infuse warmth and character into every space. Through the artful layering of one-of-a-kind and handcrafted elements, we create homes that feel thoughtful and deeply personal designed to stand the test of time, both in style and in function. We obsess over the little things because we know they make the biggest impact. From ensuring your coffee table is the right height for your sofa to curating textures that invite touch and speak to one another, every decision is intentional.

While the vision may be grand, the process doesn’t have to be overwhelming. With our expert guidance, we remove the stress and endless decision fatigue that often comes with a remodel. Our role is to streamline the process, anticipate challenges before they arise, and ensure that every detail is thoughtfully considered—so you can actually enjoy the transformation of your home.
