Now now! No door...hatch! (No walls, bulkheads, decks not floors!!)
Very well....carry on!
Mason bee house......I wonder if you could could just rubberband the empty tubes and put them in an empty number 10 coffee can then hang it somewhere protected near your orchard and garden? (Cut a piece of sheet metal and curve it over the top, secure it in place to protect it from rain.)
Pete you are right about the bee houses. I googled Mason bee houses and then clicked on images. People use cans, even just banding the tubes together. In our climate west Michigan they need a little cold protection. Round is a good way to go. Lots of designs to pick from.
You’re right about the hatch. Sorry! :)
Also, need any really heavy manhole covers? LOL!
