Mix Room - Help me find my symmetry! Sketchup Included

Hi everyone! So I'm moving into a new house, with a large room designated to be my mix room. However, I'm having trouble deciding how I'm going to set up my mix position in a way that makes acoustic sense. If you look at the design, one wall is floor to ceiling glass sliding walls. Another has a recess and a corridor, and the only practical line of symmetry seems to exist with my back to the glass wall. But then I have to work my desk and speakers around that sink - which I'm unable to remove! In terms of constructing anything to even things out, I'm not very keen on the idea of going all out putting up gyprock walls and such - any money I invest in sorting out this space I'd like to try and spend on items I can take with me. IE Gobos and things that can be moved around. I expect to have clients come through to listen to mixes and potentially overdub parts if it's appropriate for the project. So keeping things cosmetically appealing is important too. If anyone can see another solution to my room or any general advice I would really appreciate your feedback, Thank you very much :)

any other rooms in the house available? maybe a smaller room with less issues is better and make the big room a nice lounge for clients or family. how long to you plan to be in the house? if it's several years, you might consider capping the pipes and removing the sink etc to make a reasonable space and use some of John's room components to treat the space.

Cheers Glenn, Unfortunately the answer is no, not really. To fully explain my situation, I'm 21 with a physical disability, thus in a wheelchair, and my Dad and his wife have bought this house because it's previous owner was in a wheelchair too and designed and built it for his own use. This part of the house is essentially "mine" because it's got voice controlled/motorised doors/windows/curtains/etc and is acoustically isolated from the rest of the house (two doors and gyprock in the roof), but I'm paying rent for it and can't go tearing things up and making huge changes. However, I am expecting to be there a few years, maybe 5 or so, would it be reasonable to think that there might be a none-permanent way of removing the sink? I might be able to talk them into letting me do it if I can put it back when I leave - I aspire to move my work into some piece of industrial/commercial space in the future. In the "dealing with it" line of thinking, would it be possible to somewhat build my own mix space within the room out of some form of free standing walls? Then I could potentially position myself slightly off centre in the room, and although the low end would essentially still be responding to the larger dimensions of the room, I might be able to develop some sort of predictable and treatable space from the midrange up? Then I can turn the space around the sink into a little kitchen ;) Is this a realistic idea? Sorry if these ideas are still very basic and formative, I'm trying to get a picture of what solution I should invest time and effort into, and really appreciate the feedback from those more experienced. Thanks!

n.p. i think you should be able to negotiate removing the sink with an option to reinstall it since you only need to turn off the water to it and cap the pipes. that will go a long ways to making the space more friendly to your purposes. maybe start with free-standing absorbers and treatments to leave the space as open as possible and still get reflections under control. some heavy drapes across the window wall will help there. for vox or other overdubs, you could use the same concept or gobos for isolating a small area.

You sir, are brilliant! Thanks so much for that. :D

Okay, so I had a go throwing together a plan based on your treatment Glenn, and when I did this I hid the sink on another layer, put in everything I hoped to fit in the studio, then threw the sink back into the picture for a laugh, but surprisingly it fits. So I'm wondering if the sink might affect the performance of my bass traps in any significant way? Although as I figure it, given the gap is 70cm from sink edge to adjacent wall, where the bass trap sits, any frequencies larger in wavelength than 490hz will diffract around the sink and thus their energies should still be absorbed by the bass trap. Right? So my biggest issue with the sink would be reflections off it, but given that the only frequencies radiating backwards off the speaker should be low enough that they wont really be affected by the sink, everything should be ok? If I can keep the sink that would be good from an independence point of view, the less I need the other end of the house the better, but if it is going to do significant damage to my listening environment then that's a sacrifice I'll make. The file is too large to upload directly onto the forum now, so I threw a link up on fileden. HERE (Right click, save link as should do it) And no, I don't have a C24 :( But I hope to, and designed my custom desk to fit one should I ever be so lucky :)

the only thing the sink might do it force your layout to be suboptimal if you need to move closer to that wall and any resonances from the enclosure.
