Following the platform bed, I wanted to explore building a modular bookcase system. It is designed to fill an entire wall 3600mm wide and 2400mm high in my house. Again its CNC cut plywood that I drew out in Illustrator and had cut out of 18mm birch plywood.

The verticals were cut to allow the horizontal braces to be slipped in and out. The weight of the horizontal shelves held them in place. The braces have pegs which reached up into the shelves as well. So it is designed to lock itself together without screws.

Each shelf spanned 765mm across and using 18mm birch plywood. After a few months I was worried that the selves were slightly bowing under the weight of some very heavy art books. So I removed the shelves and reinforced them with 10mm plywood strips that I glued to the underside. The ply runs vertically along the thin reinforcing strips but horizontally across the shelves. So the ply run against each other so there is now no chance of the shelf sagging.
