David,

I know a company in Texas that can provide you a 120 sf (10X12) "skid mounted" pre-assembled or knocked-down building. They can hook you up with a firm (or they will) to come out and erect it for you. They will fabricate the skid and send it out with the metal sheets and all the material needed to erect it if you don't have a yard that will allow big equipment to come in and drop it in your yard. Erecting it is best left to the pros.

They made steel buildings for me when I was buying them for utility service. I would guess that a basic 10X12 knock down building will run about $12000 + maybe $3000K to erect. You can option for insultion on the walls and ceiling. I've even had the floor insulated. I don't know what your budget is, but if you are interested e-mail me for the contact info. There are lots of companies out there that will build you a skid mounted steel building with varying prices. I mentioned Texas, because shipping cost would be less for you.

No gas company will let you build on their easement. So forget about concrete slabs or sonotubes. When they do a right of way/easement survey you will be asked to tear it down. A skid mounted building (steel skid) might be pulled/towed on/off the easement if you have the means.

Of course building it on a treated lumber skid works too. Don't know what you other building requirements/codes are.
