Five Unique, Highly Efficient Deltec Homes

In recent years, prefabricated building has gained more and more recognition as a “better way to build”. In addition to being faster and more energy efficient, prefab homes can be customized to fit your needs and personal taste. Whiles the rest of the world is just now catching up, we’ve known about this since 1968! Offering designs from round to traditional to modern, each Deltec home can achieve any level of energy efficiency, from high performance to net-zero.  This list is a good testament to how everybody has a different vision when it comes to their dream home.

With a goal to optimize his views and be as energy efficient as possible, this homeowner chose a custom, round Deltec. He also acted as his own general contractor and did a lot of work himself.

5. Grid-Tied

Determined to live in a high performance home, this couple chose to build a round home because of the inherent energy efficiency. Since there is less surface area and better airflow in a circular home, heat gain and loss is drastically reduced. Starting with an efficient building envelope makes reaching higher levels of performance easier. The fact that they can enjoy their view of the Shenandoah Valley from nearly anywhere in the house is an added benefit!
