Asymetrical Control Room

Hello, I'm building my studio but due to budget issues I'm thinking of not doing the isolation in the CR yet. I'm currently building the live room and rough drawing the CR design. If I don´t do the CR, I would temporarily treat it and use it in the current room left for it. The problem is that it would be a bit asymetrical, not lot's. Do you think I will have lots of stereo imaging problems? The CR is about 26m2/85ft2. This is the construction project threat. http://johnlsayers.com/phpBB2/viewtopic.php?f=2&t=20642 Rough plans: Thanks! :)
