Basement Mastering Room Construction

My wife and I just moved to a new house (outside of Nashville, TN USA) and I quickly realized I have no place to work for my active mastering business. (actually I knew ahead of time but now I am facing reality.) We have been here just over a week and I have already started construction. I am leaning toward building a "typical" Sayers control room in the space drawn below. I have been reading a lot around here but am still looking to properly proportion the size and angles of the control room to maintain a RFZ. This is a drawing of the floorspace within the framing I am doing right now. 3 of the walls are concrete and will likely be surfaced with 1" or 2" thick extruded polysteyrene (so I guess one could subtract 2" from the width and 4" from the length depicted below. BTW, I was originally inspired by these drawings at: http://lipinskisound.com/download/Lipin ... d_room.pdf I am not able to flush-mount speakers in the front wall (simply because I don't own suitable "mains") but may like to design for future flush mounting... The Lipinski room shows free standing (Lipinski) monitors in what looks like an RFZ room. I need to design for free standing for now...

Obstacle #1 was the stairs needed to be turned. Maintaining code (when done) for the stair is what dictated the width figure of the new room. I still need to build the dogs a dog house too, but can't tear myself away from the studio work...

Obstacle #2 was the basement window. I figured the back of my room would be bass traps so I indented the room to keep the window functional.... That small indent sure used a lot of extra 2x4's.

Obstacle #3 is this water pipe... I am waiting for my wife to go to work before I do the "plumbing". This is right where a stud falls on top plate... I thought the wall would go up in one day, but the framing has taken 3 days because I've had to "stick build" it to get around stuff like this...

Obstacle #4 was this trunk-line. I was stressing about this the most because I had never worked with this type of HVAC. It was REMARKABLY low-tech and I feel I did a better job in some ways than the original installer. I will need to make one flexible run across the width of room in the very back...

welcome! it looks like you have some challenges. it would be helpful if you could post the details - isolation requirements, equipment, etc etc and your goals for the space 5.1, stereo, etc. looking at what you've accomplished so far looks to be low isolation (assuming its not a problem for you) and the ceiling height seems fairly low for a mastering room (although some folks around these parts also build mastering rooms this way... :twisted: ).
