Shelter Institute

What Shelter Institute does

Shelter Institute is a family-owned timber framing education and construction company founded in 1974 and headquartered on a 70-acre wooded campus at 873 U.S. Route One, Woolwich, Maine. Now in its third generation of family leadership (founded by Pat Hennin and co-founder Patricia K. Hennin), the company operates three integrated lines of business: Shelter Courses (in-person and online instruction in timber framing, woodworking, building science, electrical, plumbing, sharpening, and beekeeping), Shelter Design Build (custom timber frame home and barn design and construction), and Shelter Tools (specialty retail and e-commerce stocking premium brands such as Tormek, Gransfors Bruks, Robert Sorby, Starrett, Sun-Mar, Velux, and Vermont Castings).

The technical foundation is traditional hand-cut wood-to-wood joinery (mortise and tenon, dovetail, lap joints, through-tenons, birdsmouth notches) combined with Structural Insulated Panels (SIPs), which Shelter has been installing for over 25 years to deliver energy-efficient building envelopes. Instruction is anchored in a 10,000-square-foot heated workshop on the Maine campus, where students cut and raise full-size timber frames during multi-day intensives such as Purely Post & Beam. Supporting technical content covers metal roof penetration methods (EPDM flashing boots/Dektite), Velux solar-powered skylight integration, and Land Ark natural wood oil finishes.

Shelter Institute generates revenue through course tuition (ranging from approximately $45 for a half-day workshop to over $1,000 for multi-day intensives), specialty tool and book sales, pre-cut timber frame kits (a 24x24 Eastern White Pine kit listed at $18,900), and custom design-build project fees. Distribution combines a physical storefront, two e-commerce sites (sheltertools.com, sheltercourses.com), phone orders, and an annual trade show circuit (Common Ground Country Fair, WoodenBoat Show, Northeastern Woodworker's Showcase). The customer base consists of individual DIY home builders, hobbyist and professional woodworkers, women entering construction trades, veterans using VRAP benefits, beekeeping enthusiasts, and occasional mid-market residential design-build clients.

Expansion highlights6 records

Others

• Tormek: Swedish manufacturer of water-cooled sharpening systems. Shelter is an authorized US retailer and teaching partner; relevant as a key ecosystem player where Shelter serves as channel and brand ambassador.
• Fine Homebuilding Magazine: Taunton Press publication covering residential construction including timber framing and energy-efficient building. Serves the same DIY/owner-builder audience Shelter targets, with content that complements rather than competes with Shelter's paid courses.
• Timber Framers Guild: North American professional association for timber framing practitioners. Not a direct competitor but the industry's umbrella body; Shelter's prominence in the guild reinforces its positioning as a category leader.

Regional players

• The Barn Yard & Great Country Timber Frames: Connecticut-based post-and-beam and timber frame builder offering kits, design/build, and custom barns. Competes with Shelter's design-build and kit business but serves primarily the Northeast US market with broader product range.

Direct peers

• Yestermorrow Design/Build School: Warren, Vermont-based non-profit offering hands-on design/build and sustainable building workshops. Closest comparable to Shelter Institute: similar curriculum covering timber framing, small house construction, and owner-builder skills with a residential workshop model.
• Country Workshops: North Carolina-based craft school offering timber framing, woodworking, and log building courses. Shares Shelter's hybrid education/retail positioning with tool sales and traditional craft instruction.
• Heartwood Owner-Builder School: Massachusetts-based school teaching owner-builders carpentry, timber framing, and home construction through intensive residential courses. Directly comparable to Shelter's model of multi-day workshops for self-builders.
• Fox Maple School of Traditional Craftsmanship: Maine-based timber framing and traditional craft school teaching hands-on courses in post-and-beam construction, much like Shelter's Purely Post & Beam program. Both target owner-builders seeking traditional craftsmanship education.

Broad incumbents

• Bensonwood Homes: New Hampshire-based timber frame design/build firm operating at much larger scale than Shelter, with production facilities and panelized home systems. Comparable in craft and approach but broader scope includes commercial and multifamily projects.
• New Energy Works Timberframers: New York-based timber frame design/build and solar company with manufacturing facilities, prefabricated panels, and commercial clients. Larger-scale competitor in the same timber framing and energy-efficient building space as Shelter.
