About Us

Samuel H. Williamson Associates (SHWA) have been designing notable and meticulously detailed landscapes since 1991. Our projects reflect a diversity of styles, influences, and responses to climate, topography, and regional context. Each site and design is considered with regard to its individual opportunities and architectural context and history.

Our design process is always guided by the overarching belief that garden spaces should gracefully combine beauty, comfort, and utility. Our approach to design has given us the opportunity to create beautiful landscapes for residential, commercial, and institutional sites and clients. We thoroughly enjoy transforming our clients needs and desires into compelling garden spaces.

Our services have included master plans, schematic designs, planting plans, construction documents, and construction administration. Always our process involves close communication with clients and contractors.

While our office is in Portland, Oregon, and we have done projects throughout the city and surrounding areas, we also love to travel. We have done work throughout the state including the Oregon Coast, Central Oregon, Salem and southern valley. Other projects have taken us to Seattle. We have worked extensively on the East Coast.
