Partially factory-built OSB SIP (oriented strand board structural insulated panel) getaway cabin. This 1 bedroom unit makes use of 1-3lb EPS insulating foam at its wall core, sandwiched between two structural OSB skins. The v2 treehouse features a site-built wood-framed patio & observation deck to gaze at the stars.

As tested by the U.S. Department of Energy, SIPs have been proven to outperform conventional frame construction by at least 66% for energy efficiency, & can be up to 2.5 times stronger than conventional framing, while reducing the framing time by over 50% with superior noise and weather isolation.
