9. Texas Round House
The Texas Round House was developed by Shawn Dehner at The Small House Catalog. This design is quite unusual; you do not see a lot of round homes. The plans incorporate solar power, a fireplace for heating, concentrated plumbing, and plenty of other outstanding features. If you visit the source link, it indicates that free plans are available—you probably need to contact Shawn Dehner to get them. You can also buy them for $25 each, but he indicates that is only necessary if you are in a jurisdiction where you need to submit the plans without watermarks.

10. 5×8 Tiny Market House
This is not actually a tiny house you can live in—it is a tiny market stall which is designed to mimic the appearance of a house. I have included it here in case you are looking for something clever you can take with you to the farmer’s market—or a cool design for a shed.

11. Tiny Gypsy Wagon
On a really, really low budget? You might wonder whether you can afford a tiny house, but this amazing tiny gypsy wagon by Hypha proves you can. She reports that she managed to build her awesome tiny house for just $2,000, and that it took around 50-100 hours to do it. Within six months, it paid for itself. She has explained her entire process in thorough detail on Instructables.

12. The Micro Gambrel
The next few tiny house plans all come from a company called Choo Choo Tiny House. This one is free and features a charming gambrel roof. Gambrel roofs offer a spacious interior compared to a simple pitched gable. The house’s width allows it to fit on a trailer so that it can be moved from place to place.
