Luke Danielson sent me this interesting concept for an outhouse that I thought would work for someone with a tiny house. Here is what Daniel has to say about his design:
I was skeptical at first but after reading Humanure (everyone should read this book!) I was inspired to design an outhouse that incorporates a composting toilet. I know there are many out there that have been doing this exact thing for years, but I’d like to think that with the use of SIPs, the Trösta (“comfort” in Swedish) could be one of the most efficient.
With R-28 closed-cell SIP walls, roof, and floor, the unit would require very little input to heat or cool. Plus, with temperature being crucial to the composting process, it just makes sense to have a highly insulated outhouse. I designed it with the use of 4×8, 4×9, and 4×10 sheets of OSB to keep scrap and price to a minimum. With is being a bit larger than typical outhouses, you could use that extra space as a storage shed, or even split it with a divider wall for two toilets for a Men’s and Women’s unit.
With the use of the ICS’ camlock system and one-piece corners, the unit could be closed-in in just a few hours.
