new studio: basic questions

I am a noob on here and have read many, although a fraction, of posts. I have gained quite a bit of knowledge in what types of materials to use. However, I do have a few questions. I have been in construction near all my life, and realize building a studio is quite different. I am working with a musician who wants to turn his storage shed into a basic studio. He needs to have only two rooms: a control room and a vocal booth. The shed will house the studio and some lawn equipment. The usable portion of the shed is approx 16' x 24'. The ceiling is 8' along the long walls and is vaulted to flat in the middle. His idea is putting the vocal booth in one corner and placing the mixing console in front. I am not very good with the sketchup, but I did my best. It is not to scale, and the top is north. From my reading of the posts, the second layout would be better, I think. My reasoning is the sound from monitors would be traveling down the longer and more symmetrical area? The north part of the building faces a road which has quite a bit of car and large truck traffic. The south end of the building will house the lawn equipment, but has a roll up garage door. I have an idea as to how I am going to soundproof, but I would like some feedback as to the acoustics aspect. Any thoughts would help. Thanks

"My reasoning is the sound from monitors would be traveling down the longer and more symmetrical area?" Yes, in a general sense, this would be a better position than facing a corner.

Hi "TexDad". Welcome! Yes, you have the right general idea. Room symmetry is important, and so is having a decent distance between your speakers and the rear wall, so #2, with the speakers facing down long axis of the room, is preferable. - Stuart -
