Meet Gin Treadwell

With an editorial eye and a curator's sensibility, Gin Treadwell designs residential interiors that feel timeless, inviting, and always reflective of the people who live in them. She understands how important comfortable living is for families, and she believes beauty and function can, and should, coexist. Serving clients across Santa Clarita, the San Fernando Valley, and Los Angeles, Gin brings a full-service approach and a genuinely personal touch to every home she designs.

Originally from Seattle, Gin moved to Los Angeles after graduating from the University of Washington and has been a proud resident of Southern California ever since. When she isn't designing, she's happiest at home, drawn to the same warm, lived-in comfort she creates for her clients.

A Designer-Led Boutique Studio

Gin Treadwell Interiors is a boutique, designer-led studio, which means Gin is personally involved in every project from first concept to final styling. Rather than handing your home off between account managers, she works with you directly, managing every layer, remodels that rethink flow and function, furnishings, color, art, and the finishing touches, so the process feels seamless and the result feels whole. Her attention to detail, always with the bigger picture in mind, is what makes each space feel considered from top to bottom.

Style, Collaboration, and Personalization

Gin's design philosophy is simple: timeless design for modern living. Her signature style is a harmonious blend of old and new, mixing fresh pieces with treasured family heirlooms and layering in color and texture to create rooms with real depth and soul. Working across a range of styles, from organic modern and transitional to modern farmhouse, California casual, Spanish style, and modern eclectic, she adapts her eye to your home and the way you live rather than imposing a single signature look. Every project is a collaboration, shaped by your tastes, your routines, and the story you want your home to tell.

Why Clients Choose Gin Treadwell Interiors

More than anything, Gin is known for the close, lasting relationships she builds with her clients. Her Best of Houzz recognition, earned for 11 consecutive years, is based directly on client reviews and completed work, a reflection of the trust and care she brings to every engagement. She is honored to call many of her clients friends, and they return to her, and refer the people they know, because working with Gin feels less like hiring a designer and more like partnering with someone genuinely invested in your home.
