We believe every home should be a thoughtful reflection of the people who live in it, balancing timeless design with the way our clients truly live.
Johnna Martin and Jeff Larsen are the creative partners behind J Studios, brought together by a shared passion for thoughtful, inspired design. Johnna began her career by building her own interior design business while raising her family in Southern California. After relocating to Salt Lake City, she joined a Park City design firm, where she met Jeff. The two quickly recognized a mutual respect for one another’s natural talent, creative instincts, and approach to design. That connection soon grew into a partnership, and they ultimately left the firm to establish J Studios—combining their individual strengths and shared vision to create interiors that feel collected, personal, and uniquely reflective of the people who call them home.

Full-Service Interior Design
Our most comprehensive design process begins as we get to know you and your project. With thoughtful planning and collaboration, we’ll create a cohesive vision for your home and follow it through to the final stages. This service begins with conceptual design and includes floor plans, interior and exterior elevation, custom millwork and cabinetry, and full specification of every detail needed to create a timeless, personal home.
Remodel and Renovation
Leading a project to help a family home reach its fullest potential is the heartbeat of our work. By respecting and enhancing existing architecture and maintaining a strong sense of place, we make any home more livable, personal, and beautiful.
Furnishing
For new homes or those not in need of extensive changes, our furnishing service can help your space better reflect your lifestyle and unique needs. We’ll select furnishings, wallcoverings, lighting, rugs, window treatments, and all art and accessories that turn a house into a layered, curated home.


"Johnna and Jeff were absolutely wonderful to work with on the renovation of our Deer Valley condominium. They are excellent listeners and immediately understood our style vision, design preferences, and functional needs. The proposed furnishings were all on target and gave us a wide selection from which to choose. Our turnaround time was very tight, and they did a fantastic job of delivering the renovation in a very short timeframe. They – along with their staff and subcontractors - are all very professional and responsive. We look forward to working with Johnna and Jeff again!"
