Cathleen Quandt and Patrick Sheahan bring their respective experience and perspective to each project in a fluid collaboration. Cathleen, with a first degree in fine arts and a second in architecture, approaches with an eye to composition, color and materials. Patrick, with experience in both construction and architecture, brings an analytical approach and depth of experience in both residential and commercial work. Patrick began his career with solar and earth-sheltered design, and continues with a sustainable approach to construction systems and materials. Patrick and Cathleen execute all aspects of the design through to the smallest detail, believing that the success of a project hinges on the harmonious integration of function and aesthetic.
