We’re Jonathan & Ashley Longnecker. Our family is building an off-grid desert homestead from the ground up using sustainable techniques like earthbags, permaculture, solar & rainwater catchment.
Help raise funds for our Roundhouse by joining us for a homestead tour, sustainable education Q&A, and delicious homemade food.

Learn More & SignupBack in 2020 we discovered hyperadobe earthbags - a UV treated raschel mesh tube that can be filled with dirt in any shape or length you wish. It's cheap, strong, and insulating. Since then we've laid thousands of feet of bag, published hundreds of videos, run workshops, and created educational guides to help others along their journey with hyperadobe.
Our traveling and boondocking adventures led us to buy 11 acres of raw, unfinished land in the high desert of SE Arizona. We're literally building our homestead from the ground up using natural and sustainable alternative techniques like earthbag, water catchment, solar power, and more.
Even as far back as the Airstream (aka our Tiny Shiny Home) we've loved getting nerdy with solar power. Moving to an off-grid homestead allowed us to experiment and learn all kinds of new ways to power sheds, pump houses, animal shelters, and even our home.
Our videos are made possible by our Tiny Shiny Homies - they get early access to ad-free videos, special behind-the-scenes updates, & goodies like exclusive stickers, digital products, and name drops in our videos. Try it Free for 14 Days!
Signup & Become a HomieWhere it all started for us. After trying to travel in a brand new 5th wheel we sold it, bought a 1972 Airstream Sovereign Land Yacht and completely renovated it for boondocking and off-road travel.

We're continuing to push the boundaries of Lavacrete to create a beautiful, unique accent wall in our Hyperadobe Roundhouse complete with outlets, networking, 3D media insets, and inset lighting. All tinted and poured to a single monolithic color with natural layers and variations. It's gonna be cool.

If you've been following along you know that we're super excited about Lavacrete, an under-the-radar alternative building technique that uses scoria sand combined with portland cement, lime, and rebar to create thermally efficient, highly compressive walls that need no finishing work.

With the hyperadobe earthbag walls finished, we begin the most complicated part of the build yet - the roof. Join us as we create a custom bond beam, build the metal roofing structure, and panel the whole thing.

In our first series of roundhouse videos we designed, planned, and set the foundation for this unique eartbag home. The second series of videos focused on building the earthbag walls, installing doors and windows, and more. The third series saw us continuing to build the walls to the tops of our doors and windows. Then we rant out of steam.
The Roundhouse Rumble is a monthlong earthbag extravaganza that will see Tiny Shiny Home making one last push to finish the earthbags on their hyperadobe roundhouse. Aided by an articulating boom lift, and lots of new friends, they are giving themselves 30 days to lay the final bag, and are documenting the steps with daily videos.
