This house is located on Lake Metigoshe, one mile from the Canadian border. The lake borders Bottineau County, North Dakota and Winchester, Manitoba. The home is a complete SIP project, including the garage and walk-out basement wall.

Nostdahl Liptack Architects have used SIPs in several of their previous projects and sold the family on the precision of construction, speed of construction, strength, and energy efficiency. Owners did more research and decided that building with SIPs was the only way to go.

SIP wall thickness: 5 5/8" EPS Core
SIP roof thickness: 11 7/8" EPS Core
