Expand your space without leaving your home. We design and build seamless additions that match your lifestyle, your needs, and your existing home.
An Accessory Dwelling Unit (ADU) is more than just additional space — it’s a flexible solution that adapts to your lifestyle and long-term goals. Whether you’re creating a private living area for family, generating rental income, or simply adding functional space, an ADU offers lasting value.
With changing zoning opportunities in Washington and Oregon, homeowners now have more flexibility than ever to build secondary living spaces on their property. A well-designed ADU not only enhances usability but also increases overall property value.
At Nick and Sons, we approach every ADU with a focus on smart design, efficient use of space, and seamless integration with your existing property — ensuring it looks, feels, and functions like a natural extension.
A great home addition isn’t just about adding square footage — it’s about creating a space that integrates perfectly with your existing home in both design and function.
