Our hybrid practice merges design strategy and concept design.

Strawn + Sierralta helps clients figure out “what to make” before working on “how to make it ”.


Strawn + Sierralta integrates a methods-based, human-centered approach with progressive architectural systems-thinking to tackle a wide variety of projects. 

We are deeply committed to investigating the specific contexts and qualities of each project. Our goal is to find solutions that are meaningful, functional, and innovative.


We conduct generative user research, from in context, one-on-one interviews with end users, to co-creation sessions with client stakeholders. Discovering what users value and how they navigate through the world is the foundation for every project.


Today, services are more complex than ever, often blending multiple digital ecosystems with a series of spatial settings. Unpacking these hybrid journeys and sharing them in highly visual and approachable ways allows the project team to design breakthrough user experiences.


Experiential prototypes move projects forward faster. Bringing them into the process as early as possible allows users to give feedback when cost of discovery is low. Prototypes are utilized across the entire design process to pose the right questions at the right time. 


Our backgrounds are very distinct, yet complementary. 

We are professionally trained in design research methodologies, strategic planning and architectural design. Strawn + Sierralta work on projects independently, in joint collaboration, and in partnership with other talented individuals and organizations. 


Strawn is a design strategist and service designer with a background in zoology and architecture. He was trained at IIT's Institute of Design in user-centered design and ethnographic research.

Brian grew up on a family farm in the flat middle of Illinois, where he lived in an underground house and raised a troop of spider monkeys. Since then he has lived and worked in China, India, Holland, Italy, Hong Kong, Venezuela and the United Kingdom.

He received a Master of Design from IIT's Institute of Design, a Master of Architecture from the University of Illinois at Chicago and a Bachelor of Arts in Zoology from Southern Illinois University at Carbondale.


Sierralta is an educator and Venezuelan architect. Trained under a Fulbright Scholarship, she is currently an Assistant Professor at University of Hawai'i at Mānoa School of Architecture, where she leads the Basic Design Studios and teaches special topic seminars on design communication. Previously, Karla was the director of the first year graduate studio at Illinois Institute of Technology's College of Architecture where she was a Studio Associate Proffesor .

Karla grew up on the Caribbean coast of Venezuela. She has a passion for travel and languages. Before moving to the United States, she studied English, French and Italian, in addition to her native Spanish.

She received a Master of Architecture from the University of Illinois at Chicago and a Bachelor of Science in Architecture from Universidad del Zulia in Venezuela.

Partnerships and collaborations include: Chicago Architectural Club, Chicago Architecture Foundation, Landmarks Illinois, Graham Foundation, BRT Steering Committee, Chicago Transit Authority, Chicago Department of Transportation, IBC Engineering, Louis Shell Structures, Martin Thaler, Dugdale Strategy, FogPilot, and AIA Chicago.


Our work has been recognized nationally and internationally. 

Karla and Brian have been invited as guest critics and lecturers at a wide range of universities and institutions. They have also acted as jury members for multiple architecture and design competitions, and served as Co-presidents of the Chicago Architectural Club.

We have worked on projects for:
