ADU's & Additions

When your home needs more space or flexibility, a well-planned addition or ADU can be a smart long-term solution.

At Edelweiss Construction, we design and build home additions and additional dwelling units with a focus on thoughtful planning, quality craftsmanship, and clear communication. Whether you’re expanding your living space or adding a separate dwelling, our team helps guide the process from concept through completion.

• Are planning a long-term investment in your property

• Value quality craftsmanship and thoughtful planning

Each project is designed to complement your existing home while meeting your specific needs.

Featured above is a custom ADU and home addition in Corbett, OR. While ADUs can be built as separate structures or within basements and attics, this one was designed as a dedicated wing of the home, featuring all the amenities needed for a comfortable rental or a welcoming space for friends and family.

Designed to Feel Original, Not Added On

We prioritize:

• Seamless integration with your home’s architecture

• Careful site evaluation and planning

• Durable materials and quality finishes

• Clear timelines and expectations

• A collaborative, organized construction process

Our goal is to create spaces that feel intentional, functional, and built to last.

What’s the difference between an addition and an ADU?
An addition expands your existing home, while an ADU is a separate or semi-separate dwelling on the same property. We help determine which option best fits your goals.

Do ADUs require permits?
Yes. Permitting requirements vary, and we review these considerations during the planning phase.

Can additions or ADUs match my existing home?
Absolutely. We focus on design and materials that integrate naturally with your home.
