The
Studio
Malgosia Migdal is the founder and creative director of Malgosia Migdal Design, a Malibu-based interior architecture and design studio known for sophisticated, understated interiors that balance European modernism with relaxed California living. Born and raised in Gdańsk, Poland, Malgosia brings a distinctly European perspective to her work — one shaped by architecture, art, travel and more than three decades of design experience.
Her interiors are defined by architectural restraint, natural materials, thoughtful detailing and an instinctive mix of contemporary, vintage and custom pieces. Rather than following a prescribed aesthetic, Malgosia responds to the architecture, setting and individual character of each residence.
The studio’s work spans Malibu, Beverly Hills, Bel Air, Los Angeles, Aspen and destinations beyond, encompassing complete renovations, interior architecture, custom millwork and furnishings, procurement, art and styling.
Whether transforming a Mediterranean villa, restoring the spirit of a mid-century residence or creating an effortless home by the ocean, the approach remains the same: Respect the architecture. Simplify. Add warmth. Create something that feels timeless, personal and entirely at home in its surroundings.
