An architectural design studio is a practice that develops buildings and spaces through a coordinated design process. It may provide concept development, architectural drawings, interiors, material direction, permitting support, consultant coordination, and construction guidance. Ortiz Mexia Projects, Inc. extends that approach to custom homes, renovations, additions, furniture, cabinetry, and built-ins so the architectural vision carries through the entire environment.
