Living room with large sliding glass doors opening to balcony with outdoor seating, overlooking mountains and trees. Room has a wooden ceiling, built-in cabinet, wall-mounted TV, four cream-colored armchairs, a round wooden coffee table with books and decorative objects, and a woven area rug.

A studio devoted to clarity in the built environment.

Studio JYO works at the intersection of structure and atmosphere, shaping interiors that feel deliberate and quietly assured. We edit with care and refine with precision. The work is measured and attentive, guided by the belief that a home should hold together as beautifully as it unfolds. The studio's grounding in interior architecture allows design intent to move cleanly from concept to execution, with construction documents drawn to be built rather than interpreted.

About Joo Y. Oh

Joo founded Studio JYO with the conviction that interiors deserve the same seriousness as the structures that surround them. Trained in architecture, she approaches each project with sensitivity to how a home lives over time, beyond how it appears in a single frame.

Her sensibility is shaped by cross-cultural influences and a reverence for restraint, where warmth comes through proportion, material, and quiet craftsmanship rather than display. She is drawn to spaces that unfold gradually, revealing their strength in subtle ways.

Studio JYO remains intentionally measured. Joo leads a focused team united by shared standards and fluency in the language of building. The work is deliberate, edited with care, and guided toward homes that feel composed from within.

Our Team

Azul Romo

Junior Interior Designer

  • Azul studied architecture in Mexico, building a strong foundation in design and technical drawing, before turning to interiors and how spaces feel and function in everyday life. At Studio JYO, she supports the team with interior elevations, drawing sets, and design details, keeping drawings clear and consistent as each project develops.

    She is drawn to simple, modern spaces with a strong focus on materiality, often layering concrete, stone, and marble. She usually starts with the architecture and how a space will feel. Outside the studio, she is part of a running club, explores the Bay Area’s beaches, and travels as often as she can.

Junior Interior Designer

Savannah Pfeifer

  • An NCIDQ-certified designer, Savannah brings about seven years of experience across commercial, hospitality, and high-end residential design, most recently on luxury homes in Lake Tahoe and San Francisco. At Studio JYO, she works across every phase of a project and helps lead furnishings, from sourcing and budgets through procurement and installation. She is drawn to natural materials and thoughtful craftsmanship, and cares about creating healthier, more sustainable interiors. She draws inspiration from travel, art, and fashion, and most of all from the clients themselves. Outside the studio, she paints, practices yoga, and spends time in nature.

“Love working with Joo. She understood my vision and then took it to the next level. We loved working with her so much that we gave her another project and are hoping to work together on a third soon.”
