24' Engineered Tiny House Shell – Built on Purpose-Built 14k Trailer

24' high-performance tiny house shell built for durability, efficiency, and longevity. Designed in CAD and built by a cabinetmaker with custom home experience, informed by 20 years of studying building science. Relocating and can't take it with me, so I'd love to see it finished. Engineered for hurricane winds and extreme snow loads, with stamped structural plans by Paxton Rothwell. Structure & Foundation: Trailer: 24' Wright tiny house trailer (MA built), 14,000 lb GVWR. Clean title. Dry Build: Built entirely inside a garage until sealed. Framing and subfloor have never been exposed to water. Floor: 2x6 frame with 6" rockwool, AdvanTech deck, and rigid foam thermal break to eliminate bridging. Framing: Kiln-dried balloon framing with double-sheathed hurricane shear walls. Interior sheathed in 1/2" plywood. Roof: Asymmetrical gable roof with wood I-joists, massive LVL ridge beam, and a vented cold-roof design. The Envelope: Air Barrier: Continuous Pro Clima Mento Plus wrap with a 6" roof overlap. Fully sealed with Tescon Vana tape and Contega adhesive. Insulation: Merino wool in walls and roof to save weight. Exterior Siding Prep: Prepped with 1" mineral wool between horizontal furring strips. Ready for siding. Efficiency: Rough openings framed and prepped for an insulated door and triple-glazed windows. Layout & Features: Generous Headroom: Single-level space (no loft). I am 6'2" and built this with 6'6" to 10' ceilings so it feels incredibly spacious. Smart Layout: Designed for a main-floor Murphy bed and a 7'x3' bathroom with a spacious, high showerhead. Utility Bump-Out: Tongue-end roof overhang designed for an attached exterior utility shed to house solar/batteries. Utilities Prep: Interior service cavity to run plumbing/electrical without piercing the air barrier. Includes CAD drawings, 3D model, and 300+ build photos and videos. Can transport to most of New England. Serious inquiries only.
