Lessons from This Build
- Shells Reduce Entry Cost: At $35,000 for a weathertight shell with quality windows and insulation, buyers can spread the remaining finish costs over time while having a solid structural foundation
- Triple Axles Handle Heavy Builds: Three 7,000-lb axles provide 21,000 lbs of capacity, allowing for heavy finish materials like tile, full-size appliances, and dense storage without weight concerns
- Closed-Cell Spray Foam Simplifies Finishing: Pre-installed spray foam insulation means the buyer doesn’t need to handle insulation installation, one of the more technical aspects of tiny house building
- Andersen Windows Add Resale Value: Premium Andersen 400 series windows are a selling point that would be expensive to add after the fact, making this shell more valuable than budget alternatives
- Layout Pre-Planning Guides Finish Work: The designed spaces for bathroom, loft, and elevator bed give buyers a starting framework while still allowing customization within those zones

Realize that there will be upwards of 140 million North Americans displaced by rising Sea Water by the turn of THIS century. Low-Cost hosing is on my mind for you sheeple. I will be long dead, but my Grandkids might be here…3-D Printing with HEMP Hurds as feedstock is obvious using Geopolymer as a Binder seems the best choice today from my research. Combined with a Mobile (THOW) system of housing for itinerate workers who can be near the desired saltwater frontage as it climbs the shorelines. I envision a system of portable Boardwalk type structures that can shift with the tides mobile units(Park Model RV Types) just plug into and move as needed…High Rises are limited to areas above 350′ elevations worldwide…4Fathoms Designs is where I post a lot of what goes into my book series with Blurb Publishing…Maybe some of you Wealthy donors would get two of thee shells and do a side-by-side build with a $25K finish limit for mobile workers.
