This wagon was built by a collaboration of Paleotool (author of Building a Gypsy Wagon), myself (PaleoPunk), and our friend, AmericanPikey. The AmericanPikey recently retired and wanted a mobile retirement home. The vardo design presented itself as a good option because it is cheaper than a regular house, no land ownership is required (check local regulations for more details), and it's far more cool than an "off the lot" RV. The vardo is also attractive as a retirement home because utilities cost little to nothing depending on how you live. Towable on the highway, this wagon combines the design of centuries past with mobility and economy required for modern life.
The one we built here is two feet longer than Paleotool's to accommodate an indoor kitchen and more storage. The overall length of the wagon is approximately 10 feet long and is 7 feet wide. The floor on the inside is about 5 feet across with one-foot ledges extending over the wheels.
In terms of planning, the basic design sketch from Paleotool's vardo was what we started with. The wagon was made as long and as wide as was possible as was safe on the 10 foot trailer. After estimating the basic lumber quantities, a trip to the big box lumber store was made, wood stacked, and allowed to dry for several weeks. Longer would be better for stability, but the new owner was itching to start.
