Where We Work
Arizona, New Mexico, Texas, California, Mexico
We believe a City is the heart of its surrounding region, so it was easy for Merge to establish its central Phoenix office. Surrounded by both modern and historic buildings, we see constant reminders of how architecture is woven into the cultural fabric of a City and State. Our team designed our downtown office for openness, collaboration, and change.
Living, studying, and working in the Sonora Desert region has given us a passion for the landscape and architecture surrounding us. The rich history of the land and its people has embedded deep respect for the value of sustainability and design sensitive to the landscape. It offers a new, modern interpretation of all that came before us.
Who We Are
Merge Architectural Group was founded in 2012 by Carlos Murieta and Clarisa del Castillo.

Carlos Murrieta, AIA, moved to Scottsdale, Arizona, in 2002, after founding and operating his design-build firm, Murrieta + Peral Arquitectos, in Sonora, Mexico. His previous design-build-owner experience helped Carlos navigate a different way of practicing architecture and new challenges in a new country. His learning experience added unique expertise in Energy, Energy Modeling, and Sustainability with various certifications. Energy use has been a topic Carlos brings to every project at the office, assuring that blending with the environment is done as a responsible MERGE.
