Huff and Puff
Trever, sixty-three, has been a builder for forty-one years. But he says he had a revelation on a very cold day twenty years ago, when he touched the foundation of a home he was building and realized it felt warm: he'd built it using insulating concrete forms (ICF), hollow foam blocks into which concrete is poured. For the last dozen years, he's been building entire homes from ICF. "My whole house [in Milford] is made of concrete, every level, including the garage," he says. "It's mold, insect, sound, and tornado proof."
