Cornerstone has been a Sequim ADU (accessory dwelling unit) builder serving Washington State’s beautiful North Olympic Peninsula over 40 years.
We’ll make it easy for you. As a design-build firm we manage every step of the ADU design and build so you can enjoy the process start to finish. All you need to do is show us where you would like your ADU, share your vision and we will guide you through the rest.
Your ADU build experience matters, and we want you to enjoy it every step of the way. We go the extra mile by offering comprehensive specifications, detailed plans, planned milestone meetings to check-in on budget and scope, and an app the lets you track every detail that goes on and into your ADU before and during construction. In other words, you know what you're going to get before we build it.
Our in-house design team specializes in design and construction planning. Whether there's an existing building onsite or the ADU is the first building, we need to ensure that the ADU will not negatively impact the use of your lot later down the road. This requires a high-level understanding of utilities, drainage systems, and cost trade-offs and a lot of foresight. We do this through in-depth planning to establish the most logical placement for your ADU.
The ADU design-build process should be easy and enjoyable. We’re here to tell you that you can do it! Here’s how…
