We have an extra cement slab here where a tornado took away the work shed that was on it. But I'd have to get it here and that might cost as much as they're asking. If it were more like $2000, I'd consider it, though.
a. I couldn't afford it
b. A crane, to lower it into my Brooklyn row house back yard, would be very costly
c. It would be seriously illegal to set up in NYC (my 1899 house is way over the present allowable FAR–that's OK, because it's grandfathered in, but I couldn't put up anything additional on my lot).
I used a similar unit in Thailand in the early 70,s there were also set ups for color are recon work. This looks be the whole kit, D 5, all that is needed is AC and water. For those who live in Tornado alley, as I recall these units are well built and will act as a shelter.
