Experience the uniqueness of living in a Heptadecagon, a 17-sided round home with excellent structural strength, optimized energy efficiency, large open spaces, vaulted ceilings, enhanced natural light, phenomenal air flow, continuous curves, and peaceful interaction with the natural world. A round home works with nature, not against it. The Deltec home is engineered to stand up in the most extreme weather conditions. With this home's panoramic windows, you will enjoy the endless views of Cuyamaca State Park's famous three peaks--Cuyamaca, Middle, and North. The interior features high-end finishes, including engineered Acacia wood floors, solid Mahogany doors, a Lopi Answer 60,000 BTU/hour wood-burning stove, and Velux skylights with remotely operated solar-powered shades. The glass windows and doors are Marvin Integrity rated for 90 mph winds. Enjoy the custom tile, cabinetry, wine cabinet, high-end hardware, and shower features. The home has three zone areas for heating and cooling using a Fujitsu Hybrid Flex Inverter heat pump, and an optional bedroom used as an office. The new owner will also enjoy the outside decks and patios with a beautiful Southern exposure and take comfort in the Generac 22kw propane whole-house generator backup system in case of a power outage. This is a must-see home!
