Casa Bella Verde is a magnificent example of energy efficiency, sustainability, and design ingenuity. More than that, it showcases how ICF technology can be used in an astounding array of construction situations. The main home and attached guest house have a combined 9,000 sq. ft. of conditioned floor space. Yet the homes used more than 30,000 sq. ft. of ICF wall forms, and an additional 30,000 sq. ft. of ICF forms in landscaping, pool construction, and other uses. An additional 15,000 sq. ft. of Insul-Deck EPS decking was also installed.
