Look for a firm that can address design, permitting, consultant coordination, contractor communication, and construction guidance as one connected process. It is also useful to review whether the company has experience with the type of residence and project you are planning, such as a remodel, addition, historical property, or fire rebuild. A clear design philosophy and collaborative working style can also shape the final result.
