This cabin can be built in a day. Materials can be salvaged from jobsites or purchased new. It is a 12'x12' conventionally framed floor system on 24" centers that utilize full & half sizesheets of 4x8 plywood. The floor sits on cedar 4x4x12 skids. Lumber sizes are approximate and are dependent on location. Repurposed/recycled/salvaged materials work great. The wall assemblys are fabricated out of 2x4 material that is glued & screwed together with appropriate hardware and construction adhesive. Plywood gussets reinforce and hold the trusses together. Four (2-inner & 2-outer) truss assemblys make up the wall system. The two outer trusses are framed for doors, windows, patio or french units. The only plywood to cut are the plywood gussets, and front & rear wall panels. The rest of the walls are covered with whole & half sheets of 4x8 plywood. The whole assembly is glued and screwed, seams caulked and filled. The exterior is the taped and sealed using lumber yard lumber packaging wrap (like Tyvek) that can be repurposed to wrap the entire shelter with. With all seams taped and fastened the exterior finish can be any number of mud/adobe/cob configurations, dryvit, elastomeric paint finishes. Whichever exterior finish is used might require other steps and procedures. The interior of the shelter can be insulated with salvaged insulative materials, discarded clothing, shipping foam, foam board. Interior finishing can be any number of wallboard materials like scavenged lumber (for looks) or any number of interior panels or wall boards, old pallets. Add a woodstove, composting toilet, washtub kitchen & bath sinks & tub, and cabinets, and its ready to go. The shelter can be utilzed to collect rain water for toilets and washing, solar batch water heater, solar panels, wind power, and a back-up generator to help with power needs. The EShelter can be portable, permanently mounted and you can add decks or additional EShelters to make it longer and roomier. Use this shelter for emergencys, outdoor sports, a home or just a little getaway location. This is a quick and affordable to build shelter system. We have built several using salvaged materials and jobsite wastes for under $300.
