Our Story

Read More

CSHQA is passionate about sustainable, energy-efficient design and creating healthy, enduring spaces for our clients and the people who live, work and play in our buildings. We are people who listen, creating design that speaks.

Our award-winning design firm specializes in full-service architecture and engineering, interior, environmental and landscape design, telecommunications, and building forensic services.  Nearly 100 professionals design commercial, retail, hospitality, aviation, civic, education and healthcare projects.  Serving clients in all 50 states, CSHQA has offices in Boise, Denver, Phoenix, Sacramento and central Oregon.

CSHQA’s original founder, William S. Campbell, studied architecture at the University of Edinburgh. In 1889 he made his way across the United States to Boise (in the then Idaho Territory) where he founded an architectural practice.  That spirit of adventure, combined with service to community and a passion for design, has guided our firm for over 125 years.  Today, we are a thriving practice of 95+ professionals with offices in Arizona, California, Colorado, Idaho, and Oregon.

Throughout our history and particularly since the 1970s, a willingness to embrace transformation has put CSHQA at the forefront of smart, sustainable design, possibly the most critical demand currently upon our profession. The CSHQA archives include original ink on linen drawings and pencil on velum illustrations, yet today we foster a culture of working and archiving in digital, with minimal printing, as much as possible.

We embrace powerful technologies and applications, including BIM and Revit, to design with greater accuracy and flexibility.  These tools enable us to integrate and test project elements throughout the design process, leading to highly constructible documents and a smooth construction process.  They are nothing, however, without outstanding leaders, designers and support staff.

Our firm is our people.  It’s how we collaborate with each other and our clients.  It’s how we strive for excellence and respond to challenges.  We are constantly looking for opportunities to create smarter, better performing environments that enhance the way people live, work and play, and how they feel in the spaces we create.
