The simplest path to a net-zero home


5-bedroom family home

Rigel is the ideal forever home for today’s growing family. The home features five bedrooms that can be easily converted to fit your family’s ever-changing needs. There are plenty of “bonus” spaces for both work & play; an upstairs recreation room, easy access to the covered outdoor patio through double doors, and a large garage that can become a gym, workshop, or playroom. All of these spaces are located within the Extreme SIP building envelope, which means you will  benefit from the highest possible indoor air quality and decreased energy bills for years to come.
