The Boston low profile 2 shelf bookcase. If you haven’t many books, much room, or neither, this is the one for the job. Yes, it’s low, but there’s getting on for 9 feet of shelving here, and that’s not counting the top, which is the ideal height for a bit more storage.
The 2 shelves can go in any one of 3 positions, so you can tailor their heights to suit whatever books, ornaments or trophies you are displaying.
Framed plywood is used for the carcass, with pine for the shelving. Assembly time is about 3/4 of an hour for one person. You’ll need your own starhead screwdriver and hammer.
