Shelter Institute is a third-generation family business that has helped people learn about homebuilding and construction since 1974. The organization believes people can build their own homes and teaches practical skills in timber framing, general construction, woodworking, and building science. Its training is available through self-paced online courses and in-person classes at its campus in Maine, serving learners who want to develop their skills from home or through hands-on instruction.

Online offerings cover projects and techniques including post-and-beam construction, structural insulated panel (SIP) construction, tool sharpening, timber-frame sawhorses, mailbox posts, and bedframes. Courses include recorded instruction and, where specified, downloadable design or cut sheets. A free mini-course introduces timber-frame joinery and SIP wall assembly.

Beyond education, Shelter Institute offers design-build services, real estate, and fine woodworking tools through Shelter Tools. Its approach emphasizes durable, adaptable, and energy-conscious building techniques, and the organization provides course guidance and support to help students choose training suited to their projects.
