Thanks to everyone who sent an acorn and/or thumbs up! The inside just looks like an empty 55 gallon drum
.Nothing fancy!! LOL and yes, it is lying on its side. The last photo shows the lid to the drum. This keeps out spiders, slugs, etc. Just be sure to add plenty of dirt to the sides and roof if you build one yourself. We braced the front of the drum a bit with a few broken concrete blocks, small rocks, old pieces of clay pipe we'd found and a few freshly cut logs that the neighbor had just sawed from an old pine tree. The drum wasn't cut at all , it's the whole 55 gallon so kids can climb inside
