Here are a few classic Sheep Camps from the Wyoming Tales and Trails webpage. There are some great photos and some good information on their web page. I personally took a lot of inspiration from these resourceful and low-cost housing solutions.
Fiddling on the prairie. I could spend much of my life like this!
Out on the range. Looking at my Vardo, you can see my inspiration for the offset door and stove.
Again, the offset door. I get asked about this a lot. It gives a large amount of room on one side.
There’s a lot of other information and photos of western history here too. Have a look around.
