Raw land, singlewide trailer, well septic & natural building

So my partner and I are looking at buying 13 acres of pasture to build our cob/straw bale heart home.

Our initial planis to move a singlewide trailer onto the property for us to live in during construction. Singlewide trailers are allowed in our area of NC.

However, since this is raw pasture, we will have to install well and septic for the trailer. This is estimated at around $20,000.

So, my question is has anyone ever built a cob house close enough to a trailer that they could connect to the trailer’s well & septic and then moved the trailer?

Do you want to plan the building site and then place the trailer site?

Usually a well is dug where the drilling company thinks there is water.  Then lines are run to the building site and the trailer.  Or they could run to the trailer with plans to run off those later for the building site.

Same with the sewer.  Run the lines  to the trailer with plans to run to the building site later.  Tell the septic company what your plans are.

If trailer will be temporary then it seems logical to run to the building site.

If you do not plan to later remove the trailer then it would depend on you state/county septic laws.

This may not work in your area, but if you can drive a sand point, you'd have a well for a few hundred dollars.  It requires relatively rock-free soil and water within 25' of the surface.
