I use a Manhasset orchestra stand for my music. I like it because it has two lips on the bottom......the top one holds the sheet music, and the bottom one is a little 2" wide "shelf" where I keep my tuner, nail file, sanding pads, pencil, Wite-Out, red marker, etc. My stand isn't wide enough for 4 pages of sheet music, but you can get one that is. On the floor beside it, I have an end table (ordered it from the big river site.....had to look up what it was....."Winsome Wood Beechwood End/Accent Table Espresso") I keep my laptop on it, and it's still marginally wide enough to use as a writing surface.....and, more importantly, hold my coffee cup. It has one drawer where I keep things like capo, kitchen timer, extra string sets, guitar care products and cleaning cloth, etc. Below the drawer it has one door, inside which I keep notebooks with sheet music. It's about 19" wide X 14" deep X 25" high.
If I were going to build one, I'd make it slightly higher....desk height....and slightly wider. .....but I'm not a furniture builder.
