Help redesigning my room?

So here is the plan: I want to redesign my room, with my own custom furniture, everything will handmade (by me). Can I find some software that lets me create a room, and also let me design some rudimentary furniture (out of pieces, plywood) doesn't need rendering is just for visuals, cause i want to make it very effective to live in cause it's a small room and needs a lot of different storage spaces. The important thing is I have to design/draw my own furniture cause everything will be custom, nothing is predefined.
