How to build your own hobbit hole...
I kid you not. From 21st Century Bag End come detailed instructions on how you too can have your own hole in the ground.
With the circular nature of Hobbit Holes, one could use large steel pipe, but no source exists that makes low cost steel structures that I could find. But concrete... yes... concrete is the ticket.That'd be a damned expensive conversation piece; but what do I know?
All around the world, companies manufacture pre-formed concrete pipe... LARGE concrete pipe. Concrete pipe has several advantages for making Hobbit Holes. They come with an assortment of flanges, protrusions and options that allows for the creation of windows, skylights, doors, garages, fireplaces and chimneys.
As one can see, using such materials for the construction of a Hobbit Hole would make for a comfy home. Or at least a conversation piece.
