This is a single family home for a retired couple. Built to last, it will provide a safe haven for kids and grandkids to gather. With features such as an infrared sauna, standing bathtub, electric master bedroom fireplace, and large covered porch, this home will provide a cozy sanctuary for years to come. Our clients approached us with a home design incorporating SIPS wall system and ultimately chose to work with us based on our experience and knowledge of the product combined with other alternative construction methods. 
Our costs remained low as we avoided huge increases during the largest increase in lumber prices in American history due to supply chain issues during the COVID-19 pandemic.
This project was designed with a large, conditioned crawl space constructed with Insulated concrete form blocks allowing the mechanical equipment and ducting to be located underneath the home but remain within the conditioned envelope. The SIPS with GPS exterior wall assembly provided by Premier complimented the intention of the home by providing excellent air sealing and insulation qualities as well as eliminating thermal. A typical roof truss with a raised heel for extra insulation capped off the design.

SIP Wall thickness: 5.5" GPS core

Certificates: Earth Advantage Silver
