We have built dozens of garages in Seattle for decades. We take care of the excavating of the land, building the foundation, and installing the framing for your garage. Upon that, installation of the garage doors, pouring of the cement, and installation of the sheetrock & windows would be the next steps.
The question to ask you, is what types of garage do you desire?
A basic 2 car garage? Maybe two storys with a living situation above it? Or maybe a 4 car garage with room for a workstation.
Perhaps you would like it attached to your home. We've done projects specifically for RV Storage, 2-story with stairs and sheds
