Building Sustainable, Wellness-Focused Homes Across Washington, Oregon & Arizona
Your home should protect your health, comfort, and investment, not just look good on day one. At Marnella Homes, we design and build custom homes, remodels, and additions that perform as beautifully as they look, using proven building science and transparent communication at every step.
The Problem With Most New Homes
Performance You Can Measure
Building a home is one of your most significant investments. Yet most builders focus on aesthetics while ignoring performance. The result? Homes that feel drafty in winter, stuffy in summer, and rack up energy bills year after year.
You deserve better than:
- Vague promises about being “green” with no proof
- Cost overruns and surprise charges mid-project
- Poor communication that leaves you guessing
- Homes that look great but perform poorly
We take a different approach. As home builders in the Portland/Vancouver metro area, we invest heavily in design and planning upfront, using energy modeling, air-sealing strategies, and HVAC integration to solve problems before construction begins, not after you move in.

GOOD Based on 6 reviews Posted on Doug BixelTrustindex verifies that the original source of the review is Google. We were introduced to Marnella Homes through a friend. Marnella took our custom build project on, improved the design, and completed the project within the allotted schedule. In today's marketplace, there are very few companies that can do that. We are very happy with the home! Thank you Team Marnella!Posted on Andy SteiglederTrustindex verifies that the original source of the review is Google. Marnella Homes exceeded all our expectations on our custom home. From start to finish, their devotion to the client was clear in every interaction. They truly listened to our needs and made sure we felt involved and informed throughout the entire process. Their attention to detail in their work is exceptional—every finish, fixture, and feature was thoughtfully executed with care and precision. They delivered everything right on time, staying true to their schedule without cutting corners and even redoing work if not meeting their high standards. I would gladly use Marnella again on a new project.Posted on Qwan PhamTrustindex verifies that the original source of the review is Google. Building with Tony and the Marnella Homes team was a smooth and surprisingly stress-free experience. This was our fourth new home, and we didn’t think it could be this easy. Despite building on the Oregon coast, where it’s often hard to find reliable tradespeople, the entire process—from breaking ground to getting the keys—took just six months. The home is high-quality, energy-efficient, and exactly what we hoped for. We appreciated the clear weekly updates, the detailed schedule, and the billing that matched the cost estimates. After moving in, Gina and Adrian were responsive and quick to take care of any follow-up issues. We’d happily recommend Marnella Homes and would work with them again in the future.Posted on LauraTrustindex verifies that the original source of the review is Google. Tony and his team built us a beautiful home in about one year. The estimate was quite a bit shorter, but I think this is just the way things go. Using his home plan, we were able to tailor the space to our design aesthetic and partner along the way to get things right. Our PM, Damon was indispensible, a good listener and responsive.
