The interior also evolved.
The composting outhouse is also developing.
Not really a composting outhouse. This basically an outhouse with a removable holding tank. The outhouse is designed to moved forward on skids after the back panel is removed. This allows the storage tank to be removed for composting and a new tank put in place.
The storage tank is just a 55 gallon blue poly drum. It is partially buried but can easily be pulled out.
The outhouse has been built but is not in use. I am not sure of the township and state legal requirements so I am currently using a portable camping toilet. I hope to replace the tank on the outhouse with an incinerating toilet which I’m sure is legal and does not need inspection. Composting toilet are also legal in Pennsylvania but most likely require inspection. The blue tank does not even have a hole in it yet. But it looks cool. When I permanently move here I will take care of residence legal requirements. At this time the cabin is actually still just a fancy shed.
