For those of you who have been following our posts for the last few years, you might remember the first timber frame building we did for Second Nature Academy as it was the first school building in New Hampshire to become LEED-Certified, and the first non-residential building to become LEED Platinum. We recently completed a second building for the school, and like the first one, it has an FSC timber frame and SIP enclosure , and probably on its way to earning another LEED certification.
