After several years of custom home building in Orange County, Southern California, the partnership of Scott and Greg Yonkman moved to Whidbey Island and was established in 1979. Yonkman Construction has earned an unparalleled reputation in Skagit and Island County for innovative design as well as exacting craftsmanship and integrity in all aspects of the client/builder relationship. We recognize that each client and their desires are unique. Some require start to finish turn key construction, while others wish to do some of the work themselves; you choose the level of service you need. We offer pre-construction site and feasibility studies, permit processing and complete or partial home design, interior design and construction.
