12x40 feet. Vapo barrier, insulated, drywalled, painted, wired, wood stove, bedroom and bathroom with sink and shower with space for chemical or compost toilet.
Very warm in the winter with the wood stove. Three 50 gallon water barrels fitted up top with pump and water heater and outdoor attachment to refill with overflow valve to prevent over filling.

Great to hook up to existing space, or add solar panels and be off grid or put it on wheels.
Will add in a new (used for one cross country trip this year) 2024 6x12 cargo trailer ($10,000 brand new in April)

Will have professionally cleaned before taken.
