Who is Trillium Domes?

Hi, I’m Johnny. After nearly a decade as a professional dome builder, I started Trillium Domes as a way to bring DIY dome building to the world. I know I can’t build a dome for everyone that wants one, so I began sharing what I know to teach people around the world how to make their own. Our team has grown and we have now facilitated hundreds of projects all over the globe from our plans!
