Sioux City, IA

About

Stone Group Architects became part of the Sioux City community in 2018 through the merger with M+ Architects, a respected local firm founded by Dale McKinney. Since then, our Sioux City office has continued a strong legacy of service, contributing to the city’s growth and revitalization through thoughtful, high-quality architectural design.

As architects in Sioux City, we proudly serve the tri-state region with a wide range of services, including municipal, state, commercial, recreational, and federal design. Our work spans adaptive reuse, historic preservation, and large-scale civic and community spaces. Notable Sioux City projects include the award-winning Motor Mart / Bluebird Flats, Siouxland Expo Center, and the historic Benson Building restoration.

Stone Group Architects is a Service-Disabled Veteran-Owned Small Business, we’re grounded in our mission to serve those who serve others. We bring a collaborative, client-focused approach to every project, working together to create environments that are functional, sustainable, and built to last.

Whether you’re planning a new development, renovation, or preservation project, our Sioux City architecture team is ready to collaborate and bring your vision to life.
