Building started about two weeks ago. I am building the live room first, then moving everything from that side of the basement into the live room and building the control room.
Here is the design.

The back wall of the control room is from a design by Philip Newell, with a combination hangers and membrane absorbers.
The sawtooth walls in the control room were done to extend the splayed walls so all first reflections are put past the mixer into the rear absorber. This will be hollow with rockwool inside and open to the front. The ceiling will be treated the same way up to the mix position.
I have spent a lot of time learning about building speakers. The crossover will be designed based upon speaker measurements of the individual drivers after they have been mounted in the wall.
Here are some other views




The ceiling and the walls are going to be covered with moveable and removable panels so the acoustics can be adjusted. There is a large bass trap by the window with hangers.
The next post will have pictures of the construction.
