Finally built some furniture again, to replace the ugly black Billy shelf next to my desk. This is a super simple shelf made from multiplex (roughly 110x35cm) and structural bolts.
Each level is built like a bench that stands on the next one. I made cut outs for the feet on top of each level and alternated in/out for more stability.
If you copy, look out for clean cut boards, and use good router bits. I used shitty old ones and the holes and cutouts are pretty burnt (also, the basement smelled like a forest fire). I also had to do some trickery on the upper level bolts.
Total cost was about €150 (100 for wood, 50 for bolts and stuff).
is a good start for your first self made selves at home
