Frequently Asked Questions

Enertia homes have fixed requirements such as window area, wall thickness and mass, length, and volume of airflow, as well as home orientation. But otherwise, this remarkable system is very flexible.

All of these requirements fit easily into many architectural designs, either announcing or concealing the fact that you have a 21st-century geothermal home. 

We have pre-engineered home plans, which we adapt for your homesite by specifying glass, insulation levels, options, and radiant barriers for the best performance in your area.

Don't see a plan that meets your needs? Nearly half of our production is customer design work from client sketches or architects' plans. We love homes and offices of all shapes, finishes, colors, and styles. That is why Enertia is a building system that can be incorporated into many architectural styles.

Whatever plan or design you choose will receive custom modifications for your location and preferences. We want to help you create the energy-independent home of your dreams.

Enertia homes are sold as pre-cut, numbered kits. Each kit is a structural package that includes the timbers for the exterior walls and the two interior walls (Energy Walls), which form the envelope, as well as the flashing, gaskets, and fasteners to assemble the structure.

Also included are the beams for the upstairs floor system and the rafters for the roof structure.

Doors, windows, and SIPs roof panels are sold separately through our association with Anderson Windows and Eagle Panel System.

We do not include flooring, roofing, interior framing, and other materials that are better purchased at your local supply center.

We do not price our homes by the square foot but by the amount of timber and intricacy of design. As lumber costs vary, so does the cost of each house kit. Home prices are adjusted annually in response to NASDAQ lumber futures. Securing your home price often results in huge savings as lumber prices increase at a steady rate.

The total finished price of your home will depend on your taste in finishing materials, labor, and materials cost in your area, as well as how much (if any) work you do yourselves. Expect your total home cost to be roughly two to three times the kit cost.

The estimate does not include specific site costs, such as land purchase, driveways, roads, well drilling, etc., are not included in the estimate.

Our kits currently start at $240,000. Homes are shipped via tractor-trailer to your site from our Youngsville, NC, manufacturing plant. Delivery is free for homes built in North Carolina*.

Our team is available to discuss your plans and pricing; just reach out to start the conversation!

*NC sales tax must be paid on homes built in North Carolina.

If we can determine that these changes are structurally feasible, we charge a flat fee to cover the cost of drafting time, materials, and labor. Major changes involving stairways, a change of footprint, or the location of the sunspace wall will usually move the home into the custom category.

Blueprint fees for standard models are 10%; this fee will appear as a credit toward the home's purchase price. Standard blueprints include site and climate-specific modifications and detailing.

Custom home design and blueprint fees will be estimated based on the design complexity sign and will not be applied to the home's purchase price home.

Your home is a big deal to us. We are a multigenerational family business, and we take great pride in what we do! Each home is handmade, an original, just for you.

We have a limited number of production spots each year. Depending on where you are in the queue, we estimate delivery within 3-12 months from the time the order is placed.

Most homeowners appreciate this time spent doing site preparations and getting their foundations ready to build.

We will provide your builder with step-by-step instructions and support for assembling your Enertia home. Support is available throughout the process as questions arise specific to your Enertia home.

Additionally, in many cases, we can send a representative to your job site to assist in starting the process for an additional fee.
