What Our Clients Say
★★★★★
Best experience we have ever had with a contractor. Everyone who worked on our project was amazing. They actually followed their time line! If you need any work done I highly recommend them. We turned our garage into an ADU for my parents.
★★★★★
I had a great experience working with Harris & Sons Construction. Their team was professional, responsive, and easy to communicate with throughout the entire project. Whenever I had a question or needed an update, someone was always available and quick to respond. They did an excellent job managing our ADU project and kept everything moving smoothly from start to finish. The quality of work and attention to detail really showed. I would definitely recommend Harris & Sons Construction to anyone looking for a reliable and professional contractor!!
★★★★★
We hired Harris & Sons to remodel part of our house and also build an addition. The project involved 3 bedrooms, 2 walk-in closets, and 2 bathrooms. Throughout the construction process, which had a few unforeseen complications, Harris & Sons worked to meet our expectations, gave us constructive options, and pushed to keep as close to the schedule as possible. They worked with us on controlling overall cost and understood and respected our financial capabilities and limits. In the end they gave us a beautiful and good quality home.
★★★★★
From our first meeting, Christian Harris stood out. Not only is he incredibly knowledgeable about construction and design, but he also brought a level of calm confidence that made us feel like our home was in the best possible hands. He took the time to understand our vision, walked us through every step of the process, and communicated consistently, something that’s rare in the construction world these days.
★★★★★
I met with Christian and a tall young man whose name escapes me, and was very impressed by their professionalism. They gave me a quote for remodeling after major water damage. Sadly I couldn't use them as I was fighting with my insurance company at the time!! I still think about the awesome job I KNOW they would've done for me and am still upset it never happened.

★★★★★
We had Brian and his team Marcos & Jackson put in a privacy fence for us. The work done was outstanding and the fence looks great. I’m overjoyed by the job they did dealing with the ‘less-than-friendly” rock pile we live on. The work was done efficiently, clean, and fast. I don’t think I heard one curse-word uttered. These guys are clean, professional, quick, and darn good at what they do! I couldn’t recommend them more and we’ll be calling them again to put in our deck! Thx guys!!!
★★★★★
This team did such an amazing job building my pergola cover and enclosing my deck. Very professional and quality work. All of their suggestions for design were great, and I would recommend them for any project.
★★★★★
We have worked with Christian and his team for numerous projects around our home for the past year. They built and stained a beautiful fence for us, and also built a paver patio and pathway in our backyard. They are consistently friendly, communicative, and deliver high-quality work. Their employees are considerate and helpful. They have excellent follow-through from start to finish, and are exceptionally priced. We would highly recommend this team and we will continue to utilize their skills around our home going forward.
Invest in Your Home’s Value
Whether you’re considering a bathroom renovation, kitchen upgrade, or an ADU addition, these remodels drastically increase your home’s value. This means homeowners will have more equity if they want to pull out a HELOC loan, or they will get much more resale value when they decide to sell the home. Some projects recoup 125% of their costs, meaning they bring more value and make more money to homeowners than they cost.

Got Questions?
Frequently Asked Questions
1. What’s the difference between an addition and an ADU?
A home addition expands your existing living space, like adding a new bedroom, bathroom, or living area. An ADU (Accessory Dwelling Unit) is a separate, self-contained unit — often with its own kitchen, bathroom, and entrance — that can be used for guests, extended family, or even rented out for additional income.
2. Do I need permits for an ADU?
Yes, building an ADU in Bend, OR requires proper permits and must meet local zoning regulations. Our team at Harris & Sons handles the permitting process for you, ensuring your ADU complies with all city codes and requirements.
3. Can I use an ADU as a rental property?
Yes! ADUs are perfect for long-term rentals, guest houses, or multigenerational living.
4. How long does it take to complete a home addition?
Timelines vary, but most additions take 8–12 weeks from design to finish.
5. Will a home addition increase my property value?
Definitely. Additions add square footage and functionality, which increase resale value significantly.
