HD+A was established in 2004. Based in Portland, Oregon, the firm has focused on expressing ideas that are rooted in the Pacific NW region with a connection to the greater context beyond. With combined experience in commercial, educational, science facilities, multi-family and single family residential housing projects, Libby and Greg Holah have continued to maintain a multi-disciplinary studio approach. Both partners share a complimentary approach to Architecture, that addresses the specific demands of each individual project.  Our work strives to make enduring places for people. Shaping a better-built environment begins by working collaboratively with all project team members, from project initiation to post occupancy.
