Morning does anyone know the size or where I can source a base to have ago at making my own hobbit hole?

Are you meaning the famous Billbo Bagins bonsai by Chris Guise?

That is not a product, it is pure craftmanship. You need to build it from scratch yourself.

Or ask someone to do it for you. The house and the landscape took 80 hours to make, the tree some 10-15 years. So don't expect someone doing it for you at a bargain price.

Tbh, bonsai is an art and about creating ones own expression. The Billbo Bagger house is already done. Doing it again will be like painting Mona Lisa again. Every attempt will just be a lame copy. Better to come up with an own idea really.
