Twenty Five + Years Designing, Building, Living & Working in SIPs.

Green since it was a color, we built our first passive solar homes in 1982. In our quest for efficiency, long before it was mandated, we discovered SIPs as a great blend of high efficiency and strength. Since 1995 we have been using SIPs in our designs, building projects, including living and working in our own SIP office and home. We have experience from No Income Residential, Mid & High End Residential, Multi-Residential, Retail, Commercial, Municipal Town & Federal SIP projects.
