Who is CRAN (custom residential architects network)? If you practice residential architecture for individual homeowners, whether you work on bathroom or kitchen remodeling projects, additions to existing residences, or ground-up new homes, you are doing “custom” work and are part of CRAN. Inclusivity is of the greatest importance to the CRAN leadership and the future growth of CRAN. We are a “style-blind” group which recognizes and accepts all types of residential architecture design idioms and practice models for its members.
