I've re-built the garage at home to a studio, and so far I have control room + vocal booth. Now, there's one room left, which I intend to record drums and other stuff in, but mostly drums. I refer to it as the drumroom from now on.
The drumroom is 2,5 x 3,5 meters in area, so it's not very large.
It's of course large enough for getting the drums IN there, but my main concern/problem is how to make sure the drums won't sound boxy in there ? I really don't want the room to end up in the recordings. Not too much anyway.
Here's a small picture I made of the room:

The colored dots in the corners are for reference only.
As you can see, the room has a rather strange ceiling, with 2 different heights. It's kind of a loft up there, so I can stash mic stands, guitar cases and stuff on top of the black area. I'd like to keep it that way, but it does make the ceiling height over the black part of the room a little low maybe. i don't know, that's why I'm here.

Anyways. This is what I thought about doing. Feel free to correct any bad ideas I have.
Since three of the corners (blue, yellow, red) have doors nearby, I thought about having the drummer sit with his back towards the green corner, so people can still get in and out of the doors. I'd loose a bit eyecontact with him, since the studiowindow is on his side then, but what the heck.
Since I would wanna aim a lot of microphones towards the absorbing material, I'd thought about putting up some sort of absorbing materials at the top and left (on the pic) walls. And maybe the right wall too.
The bottom wall is trickier, cause it has both window, door and radiators, so it's hasn't got much area to put absorbers on.
Could I leave this wall out ? How about a heavy curtain that could be placed near the ceiling (higher ceiling here) and rolled down over the enntire wall during tracking, covering the door and window ?
That way I could control acoustics a tiny bit too.
Does heavy curtains absorb the "boxiness" out of a room ?
How about the ceiling ? Since the drums will prolly be placed at the green corner, is it enough to treat the ceiling in the black area ?
Is it possible to get a good sound out of this room at all ?
I'm gonna stop here. The more I write, the more I get the feel that I'm just rambling about something I don't know shit about.
I'll wait for a reply instead.
Btw. The room is all wooden walls, floor & ceiling.
Thanks in advance for your kind help
