I’m SO upset! WHY didn’t you post the 180 cottages for auction LAST month, or the month before?!!! Instead, you published it today. The auction was THIS MORNING. The one bdrms sold for $9000 – $14,000.
I wish I had known about it before this morning.
This is great. I can see how I can scale it smaller and use it to cook and later shower. Thanks Alex.
Any reason for the height? I could see it built on wheels, which you could roll over an old-fashioned cast iron stove or charcoal BBQ to get it started.
I will try it
