My venture fittingshub.com designs space saving furniture and puts the plans into ready-to-cut digital files so you go to any cnc-machine-enabled carpenter and cut the whole thing for a few bucks.
It is a good solution for those of us who need a desk and don't have loads of space in our homes.
This is our latest design: A double size bed + desk combination furniture.
We also have a single version, and a smaller couch + bed + desk for living rooms or spare rooms.
