I'm planing an extensive remodel of a fixer upper that I bought in December. Part of that remodel would involve a new furnace and hot water heater in a small "utility closet".
The closet would only be able to be 49" x 57" I did a mock up of it in a 3d program and was curious if anyone could point out problems with this ideas or help ease my mind and say its doable.
One of the main questions I have is whether such a short return air "plenum" would be okay. Its a small house and the furnace would be very close to the middle (single story on slab) I plan on having the proper ventways from bedrooms and such for return air to this central return grate.
Any suggestions or comments would be greatly appreciated. The light blue and light brown translucent areas are supposed to represent the wall and door respectively.

Also would installers/maintenance people hate me or would the large door keep them happy.

It's going to get very hot in there.
Is this gas? If so, then not only will you need to make sure that there is adequate high and low vents places in the walls or door (you do have a louvered door drawn in, that will be good) but you may need to have a source of outside air good good combustion.

Yes this would be a high efficiency gas furnace with pvc supply and flue. Also it would gas hot water heater that would need combustion air from the room.

If you are subject to code, make sure you comply.
I take it you live up north...if not, a return air should be much higher [hot air rises] so you can get the higher hotter air, for recirculation.
If a gas heater inside a closed area, just make sure you can service, remove and replace when the time is right. Make sure you can easily get to all your piping, and of course, all your venting should be to spec. I enclosed in the kitchen a 40gal HW Heater at my country place with propane line...whenever I leave, I turn to pilot. However, it will get hot in there, but that only keep the heater/water nicer. I left a nice open space at the bottom of the door so plenty of 0xygen can vent to the pilot flame area...this makes it draw well too
