According to Brandon Bryant, Red Tree’s president and owner, this home in Asheville, N.C. is “a testament to harmonious living with nature.” Positioned along the tranquil riverbanks near the charming agrihood community of Olivette, it offers not only a place to call home but also a gateway to a lifestyle that celebrates the great outdoors.

It wasn’t an easy build. Bryant notes that the project—Green Builder’s Green Home of the Year in the Mainstream Green category—broke ground during the height of the pandemic in 2021. The timing resulted in many challenges, including material delays, labor shortages, and price fluctuations. 

“We learned to be adaptable and overcome unexpected obstacles within the building industry,” he says. “Our clients were fantastic to work with—they were very flexible and understanding throughout the entire build process.”

The result was a custom build for a client wanting a beautifully designed home that was energy efficient, one that “exemplifies a commitment to sustainable living.”

Strategically positioned solar panels harness the power of the sun, generating clean energy that not only reduces the property’s environmental footprint but also contributes to lower energy bills. 

Meanwhile, an efficient geothermal heating and cooling system ensures year-round comfort, utilizing the earth’s natural energy to maintain an ideal indoor climate without reliance on fossil fuels. This home received a Home Energy Rating System (HERS) Index score of minus 8.

The exterior of the home is a testament to thoughtful design. Adorned with tasteful natural wood siding, it blends seamlessly with the idyllic surroundings, “reflecting the spirit of the agrihood community that values the preservation of nature,” Bryant says.

Green Living Is Assured

The home has been meticulously planned to minimize its environmental impact, making efficient use of space while maximizing the interior living areas, Bryant adds. Every square foot is thoughtfully considered, ensuring that residents have ample room to enjoy the comforts of home while leaving a light footprint on the Earth.

“Residents here enjoy the privilege of easy access to an array of walking trails that wind through the pristine surroundings, inviting leisurely strolls amidst the beauty of the landscape,” Bryant notes. “The soothing presence of the nearby French Broad River offers opportunities for boating or simply savoring the peaceful sounds of gently flowing water, creating a serene escape just steps from your doorstep.”

In addition to these natural wonders, residents have the distinct advantage of a community garden, an oasis where they can cultivate their green thumbs and connect with their neighbors. “This shared garden space fosters a sense of community and encourages a deeper connection with the land, as residents come together to nurture the earth and share in the joys of harvesting fresh produce,” Bryant says.

“In essence, this residence in Olivette embodies a harmonious and sustainable way of life, seamlessly integrating with the beauty of the agrihood community and its natural surroundings,” Bryant says. “It offers not just a house but a lifestyle that cherishes the environment, encourages community engagement, and prioritizes the well-being of its residents in a setting where nature’s wonders are cherished and celebrated every day.”
