50 years of family-owned excellence in design.

IZ design studio is a second generation, family-owned firm specializing in architectural planning and design. Founded as RFBA in Washington State by Robert Broyles in 1976, the firm was renamed with the establishment of the Nevada office in 2010.

Today, IZ design studio is owned and operated by I-Fang and Zach Broyles. Holding active architectural licenses in Nevada, Arizona, California, Colorado, Florida, Georgia, Hawaii, New Jersey, New York, North Carolina, Oregon, Texas, Utah, Washington, and Idaho, and rooted in service and design excellence, IZ design studio has become a trusted resource for municipal agencies and commercial clients alike.

In addition to their commitment to their clients, the pair have invested in advancing the community by striving to hire local, emerging designers to the greatest extent possible. Through active mentorship, with the opportunity to learn on the job, IZ design studio is helping foster the development of the next generation of Nevada architectural professionals.

IZ design studio is dedicated to enhancing communities, building brands, and elevating user experiences through design. We strive to develop a deep understanding of each client and project to deliver compelling architectural solutions that are responsive to their unique requirements and representative of their vision.

This approach allows our team to provide the highest caliber of service, expertise, and design every time.

We are invested in our community and the partnerships we’ve created. We believe in the power of design to spark curiosity, ignite creativity, break down barriers, and build relationships.


Our team is passionate about design. Details matter, and our objective is to bring our clients’ visions to life with spaces that inspire and embody the unique character of the brands, communities, and people they serve.

We develop long-term relationships with our clients that are centered on communication, respect, and results. We value the trust placed in us and consistently meet project priorities while exceeding client expectations.


We believe good design is always environmentally responsible. Each project represents our dedication to conserving natural resources, protecting the environment, and enhancing the wellbeing of building occupants.
