Watershed Structures

Builder of backyard cottages, also known as Detached Accessory Dwelling Units (DADU), and located in Snohomish, Washington. We are committed to producing forward-thinking structures, that are ecologically friendly, easy to construct, and available to those who want them, not those that can afford them. Our cottages use locally sourced materials whenever possible. We make it easy, by handling 100% of the construction on your site, so you can save you energy for the fun stuff and enjoying your finish DADU.
