Cold air return in new room

Hi,
I just added an 18' x 20' room off the back of my house which has 3 floor registers for heat/ac.
My contractor has not finished yet and there is no cold air return.
This summer I noticed a lot of hot air up in the tray ceiling that you would
feel when you turned on the ceiling fan.
I want to add a cold air return high on the wall but getting duct work to it is difficult. I can't easily go up the walls on either side of the room.
I live in a split, so there are basically three levels with a return on each level.
Two of the returns (middle floor and upper floor) terminate at the attic.
Is it OK to tap into one of the two cold air returns that end at the attic and run duct work through the attic to the new vent?
My contractor doesn't seem to want to do this. (too much work?)
He seems to want to put in a return low on a wall or in the floor, which I do not like at all.
Sorry to ramble, but I wanted to provide as much info as possible.

Thanks,
John H.

Id say do it in the attic. But the pipe you tie into up there will have to be made bigger back to the unit cold air return so you can add more return there.
