Keene Castle
More than 15 years ago, Lance Keene, a self-taught amateur builder, began building what many considered impossible: a multi-story castle perched 600 feet up on solid granite in the White Mountains of New Hampshire. He was inspired by the German castles he visited while stationed there during his military service in the U.S. Army. Today, the structure stands as a technically ambitious example of ICF construction applied to extreme terrain, severe wind exposure, and complex architectural geometry.
Granite State Sanctuary
The beautiful Granite State Sanctuary, built by Groen Construction with Nudura insulated concrete forms (ICFs), was named a top three finalist in the 2026 nationwide ICF Builder Awards, earning recognition in the “Unlimited Residential” category.

Boys & Girls Club of Central New Hampshire, Concord, New Hampshire
The Penacook Community Center served the Concord, New Hampshire area with day care and afterschool programs for decades. In the aftermath of COVID-19, and with a building beyond repair, the future of the center appeared bleak. But, in the late fall of 2021, a meeting between Cathy Furlong, president of the Penacook Community Center, and Chris Emond, CEO of the Concord Boys & Girls Club, put the wheels in motion to merge the two organizations. The result was a plan for a new, energy-efficient facility to better serve the Penacook community.
David Prouty High School in Spencer, MA
