Refined interiors, considered in every detail.

Boutique interior design studio specializing in full-service furnishings and renovations throughout Scottsdale, Paradise Valley, and the East Valley.

A More Meaningful Expression of Luxury.

We believe a beautifully designed home should do more than make an impression. It should serve the people who live within its walls, welcome the people they love, and make everyday living feel just as special as the occasions worth celebrating.

At Opal Avenue Interior Design, we work with homeowners who value thoughtful design and the freedom to enjoy their homes without carrying the responsibility of designing them. From the earliest planning stages through the final installation, we oversee the details, collaborate with trusted trades and artisans, and make considered decisions that bring the entire space together.

The result is a home that feels cohesive, functions beautifully, and reflects not only your personal style, but the life you're building within it.

HI, I’M HOLLY.

FOUNDER + PRINCIPAL DESIGNER

Thoughtful homes require clear direction.

At Opal Avenue, I lead the design with experience and discretion, shaping spaces that feel composed and built to last.

This is design for clients who value expertise, clarity, and a home that reflects their standards.

“Working with Holly was an absolute pleasure from start to finish! Her expertise, creativity, and attention to detail made the entire design process feel easy and enjoyable.”
