Project Overview
Gohlke Res
Washington
End Use:
This home is the third SIPs house the owners have built, and this one was built on the lot next to their last SIPS house. This is their forever home.
Why SIPs?:
The owners are long-time customers of Clifton View Homes. This is their third SIPS house we have built for them in the span of 14 years. Their desire to continue to live in an energy efficient home and our past performance of high quality work and service has created a trusting long-lasting relationship with them.
Benefits of SIPs:
Using SIPs on this project saved time, labor and costs as there was less preparation on site to build the house. Once the panels were received, the house was constructed quickly and efficiently. Our team is so experienced with SIPs that the process is seamless and quick. The site was extremely tight, so little room to stage materials. SIPS are able to arrive "just-on-time", saving space until needed.
Innovative Design Elements:
The small lot, and requirements for on-site septic, as well as storm drainage requirements, required us to rethink our usual slab-on-grade foundation. The clever design allowed us to overhang the foundation in a few places to increase the main and upper floor areas, while keeping the actual footprint to a minimum.
