Terrain Seattle Construction
We started in Seattle in 1994 with a loyal list of yard maintenance clients and determination to do things immaculately. Too young for a driver license, custom made bikes and trailers were the mode of transportation.
As the company grew and talent joined we expanded into landscape construction and technical excavation. Our first employee hires from outside the family are still with us – testimony to the way Terrain wants to care for each other and keep a fun tight-knit atmosphere. That reflects in the caring personable team members that you will engage with. We believe with success come responsibility and to that end, we spend a lot of time on charity projects and supporting other charities that are close to our hearts.
