About Marnella Homes: Building a Sustainable Future

You deserve more than code-minimum construction dressed up with marketing buzzwords. At Marnella Homes, we design and build homes in the Portland Metro area and throughout the Pacific Northwest that prioritize your family’s health, comfort, and long-term investment through proven building science and transparent communication.

Why We Exist

After nearly 40 years in real estate and residential construction, our founder, Tony Marnella, recognized a troubling pattern: homes built to minimum standards, sold with maximum promises, and leaving families with drafty rooms, high utility bills, and poor air quality.

He knew there was a better way.

Marnella Homes was founded on a simple principle: homes should be carefully engineered systems, not just attractive structures. We combine thoughtful design, building science, and decades of practical experience to create homes that perform beautifully every single day.

Who You’ll Work With

Tony Marnella, Founder & CEO

With nearly four decades in the industry, Tony leads our vision and standards. His commitment to building science and wellness-focused design shapes every project decision.

Design & Planning Team

Coordinates architectural design, energy modeling, and HVAC planning to transform your vision into a high-performance reality.

Construction & Site Team

Manages quality control, conducts scheduled walkthroughs, and ensures performance details are correctly executed.

Warranty & Aftercare

Ongoing support, system education, and comprehensive warranty coverage, including third-party structural protection.

What Drives Our Work

Performance Over Promises

We run energy modeling, design integrated HVAC systems, and plan air-sealing details before construction begins. The result? Consistent temperatures, quieter spaces, and lower utility bills you'll feel immediately.

Health-Focused Environments

Advanced air filtration, ERVs, water filtration, and intelligent lighting systems create homes that support wellness rather than compromise it. Your home should be a sanctuary, not a source of concern.

Radical Transparency

Fixed-price proposals based on detailed plans and realistic allowances mean no surprise costs. Scheduled walkthroughs and open communication keep you informed at every stage.

Sustainable Practices

From efficient plumbing layouts to durable, low-maintenance materials, we reduce waste and protect resources without sacrificing refinement or comfort.

Integrity in Every Decision

Third-party verification, 10-year structural warranties, and a solutions-focused approach to challenges mean we stand behind our work long after you move in.

What Makes Us Different From Other Builders in the Vancouver Metro Area

You have options when it comes to builders. Here is how we stand apart:

Homes Designed as Systems, Not Just Structures

We do extensive pre-construction planning, energy modeling, and HVAC integration before we build.

 

Eco-friendly labels are not enough. We pay close attention to air quality, water quality, natural and smart lighting, and how your home actually feels to live in every day. 

 

Whether your home is inland or on the coast, we adapt details to the environment while keeping the same high standards for durability, comfort, and efficiency.

Instead of a vague cost-plus model that can drift, we aim for clear, fixed pricing based on well-defined plans and realistic allowances.

With almost 40 years in the industry and experience across many home types, we combine hard-earned practical knowledge with up-to-date building science.

Social Proof & Community

You should not have to take our word for it.

Industry Experience

Nearly 40 years in real estate and residential construction means there is not much we have not seen or solved.

Featured & Recognized

Marnella Homes has been featured on platforms like Houzz for our work in sustainable, design-forward homes.

Licensed and Verified

Commitment to Good Causes

Our involvement with organizations like St. Jude reflects a belief that building well also means contributing to the broader community.

Happy Homeowners
