Most homeowners who decide to build understand they are making a significant financial commitment. What fewer fully consider going in is that the home they build will also make a daily impact on their health, their comfort, and their long-term cost of living. The materials inside the walls affect the air they breathe. The windows, insulation, and mechanical systems determine how much they spend on energy every month. The design choices made during construction either support a healthy indoor environment or quietly work against it for decades.

Marnella Homes was founded on the conviction that these things matter – and that building a high-performance, sustainable home does not require a compromise between quality, beauty, and responsibility. With nearly 40 years of experience in the residential construction industry and over 505 homes built, Marnella Homes has spent decades proving that the greenest homes are also the best homes.

What Makes Marnella Homes Different From Other Home Builders?

The green building space has no shortage of builders who attach sustainability language to conventional construction. Marnella Homes takes a genuinely different approach – one grounded in proven energy modeling, third-party verification, and material selections that prioritize health and durability alongside aesthetics.

What consistently sets Marnella Homes apart:

• Nearly 40 years of industry experience spanning sales, leasing, development, and construction
• 505+ homes built across a wide range of residential types, from single-family homes to townhomes and condominiums
• Energy modeling on every project to verify performance before construction begins
• Third-party verification of energy efficiency and sustainability claims
• Premium eco-conscious materials selected specifically for health, durability, and environmental impact
• Wellness-focused design that addresses air quality, water quality, lighting, and thermal comfort as core building priorities
• Featured in Houzz for design excellence

These are not checkboxes on a marketing sheet. They represent a building philosophy that has been developed and refined through four decades of hands-on experience.

What Does It Mean to Build a High-Performance Home?

The term “high-performance home” gets used loosely in the building industry. At Marnella Homes, it has a specific meaning – a home that performs measurably better than code-minimum construction in four interconnected areas: energy efficiency, indoor air quality, thermal comfort, and long-term durability.

Energy Efficiency A high-performance home uses significantly less energy than a conventionally built home of the same size. This is achieved through a combination of superior insulation, airtight construction, high-performance windows and doors, and energy-efficient mechanical systems. Marnella Homes uses energy modeling to quantify the expected performance of every home before a shovel hits the ground – so efficiency claims are backed by data, not marketing language.

Indoor Air Quality The air inside a home can be significantly more polluted than the air outside if the wrong materials are used and ventilation is inadequate. Marnella Homes selects low-VOC paints, sustainably sourced wood, and advanced air filtration systems specifically to maintain clean, healthy indoor air. Controlled mechanical ventilation ensures fresh air is continuously supplied without the uncontrolled air leakage that undermines both energy efficiency and comfort.

Thermal Comfort A well-built home maintains consistent temperatures throughout, without cold corners, drafty windows, or rooms that never seem to reach a comfortable level. Superior insulation and airtight construction are the foundation of thermal comfort – benefits that residents feel every day regardless of the season.

Long-Term Durability High-performance homes are built with materials and systems selected for longevity, not just initial cost. Marnella Homes’ commitment to premium materials means fewer maintenance issues, lower long-term repair costs, and a home that holds its value as it ages.

How Does Marnella Homes Approach Sustainable Design?

Sustainability at Marnella Homes is not a single feature – it is a design philosophy applied at every stage of the project, from site planning and material selection through mechanical system design and finishing details.

Earth Every Marnella home is designed with respect for the site’s natural conditions – orientation, topography, and surrounding environment. Passive solar design principles are used where possible to reduce heating and cooling loads through thoughtful building placement and window orientation.

Water Water-saving fixtures and systems are standard in every Marnella home. State-of-the-art water filtration ensures that the water residents use daily is clean and free from contaminants – a health benefit as practical as it is principled.

Light Smart lighting systems designed around human circadian rhythms support sleep quality and daily well-being. Natural light is maximized through careful window placement and layout design, reducing dependence on artificial lighting while improving the quality of interior spaces.

Air Advanced air filtration systems and controlled mechanical ventilation maintain indoor air quality at a standard that conventional homes rarely achieve. The materials inside a Marnella home are selected specifically to avoid off-gassing volatile organic compounds that degrade air quality over time.
