Feedback Control Room Design

Hello everybody. I've been reading articles here for some time but have never registered until today. I am trying to use a room in my basement for recording/mixing purposes. So far it's only on paper but I intend to build it all by myself even if this will take some time. Your help is of course appreciated a lot I hope my post is providing you with some good starting points for discussion. Since I am from Germany, I will use the metric system. Here are the basics: - The room: It's about 7.40m wide and 4.45m long (red lines on the plan). The height is 2.50m. Two outer walls (right and top on the plan) are concrete, two inner walls are brick walls (left and bottom on the plan). Alle four walls are rendered (hope I'm using the right vocab). There is one door about 0,80x2,00m (on the plan the outward opening one), and two windows (small basement windows about 1,00x0,60m in the concrete walls). You can see all this in my plan. - The concept: Part of this big room has to remain "musically untouched" because I (and my family) need storage. This part of the room is already fixed in its position because that's the place where a lot of network/TV/etc. cables unite and there are already shelves for storage installed along the wall. The rest of the room can be used to build in a "studio", if you want to call it so. I am not a professional musician but an ambitioned amateur and I also take fun in planning, constructing etc. What do I want to do: As a hobby musician I would like to record my own singing, guitar playing or recording other small instruments (no drums). Furthermore I would like to mix material from my bands/projects etc. Watching at other designs I thought it would be helpful to avoid parallel walls, while at the same time caring for geometrically similar left and right walls. Apart from the plan I want to treat the ceiling as well. An angle of about 12° opening towards the doors is recommended as I heard/read. After the construction there will be some fine-tuning with absorbers etc. But I am not that far. At this stage I would apreciate feedback on the general design as for example: - Is the control room big enough? - Is it possible to use the remaining room on the right for some recording (vocals, guitar)? - Should any angles be changed (of course this is limited)? - Should the sound monitors be fitted into the bass traps at the top? - Are there any practical short-comings in my plan? - Anything else? Thank you very much for reading and answering.

Welcome! Have you considered a single room approach so all of the space not allocated to storage can be the CR and also allow for performing?

Single room would be fine as long as a storage room will be available. One problem with the single room idea is that the room will then be nearly as wide as long. As I understood, this is bad.

Hello. I "killed" the smaller room. Now there is more space for the CR. If possible I would use flush mounts. The design is still geometrically balanced. I tried reflection angles and they look good. Most of the arrows lead into the big traps in the rear corners. The trap with the door can only partially be filled with rockwool. Is this a big problem? The engineer place is now situated in the middle of the room which, as I understand it, is unfortunate. To reduce rear reflection I'd probably need more absorbing material in the back because of the engineer's position. Still comments are apreciated. The big triangle in the upper right could be designed as an additional basstrap/Helmholtz or whatever is helpful. On the opposing wall I could install sth similar.

maybe turn the CR on its side?

That is also a good idea. Thank you for the drawing. But then I will lose the window. Some fresh air would be nice from time to time. I might be able though to replace the window by a ventilation unit of some kind. I will follow this idea. Thank you. I will report about any progress.

Since I am not quite sure about dimensions in the suggested plan I tried to adapt the sketch to my room planner. Am I right? I tried to gain as much CR space as possible.

that works. you could use an air exchange on the window to get fresh air and use a split unit for AC. if you need some daylight, some glass blocks in the isolation wall over the window could help get some of that into the room.
