Shelter...

There probably isn't really enough time to build a castle and you really should have more than the minimum shelter. On top of that, it should be fairly inexpensive and easy to build. Some years ago I came across a unique dome home design that incorporates the best of the geodesic dome design and greatly simplifies construction. The book is available at Amazon and it's worth checking out. If you are at all handy with tools (and I suspect you are or you wouldn't be reading this), you'll see that as really solid shelter goes, this is amazingly simple. It was written by an architect named Gene Hopster (who unfortunately is no longer with us) and is written with the do-it-yourselfer in mind. For a look, click here. There is another really fast shelter (though not as sturdy as the dome) that has been in use for centuries called a yurt. This can also be made by a do-it-yourselfer and it can be transported fairly easily to remote areas. Click here to see. They won't last as long but, if you're in a hurry, they just might be life savers. You are smart enough to decide so all I can do is make the information available and wish you the best.
