I did a long, very detailed "build thread" detailing the process on the AVSforum, back in 2010. Unfortunately all the images in that thread of the construction and finished room disappeared. They were hosted on a website that moved from free to paid subscription, and they just deleted photos from anyone who didn't switch to the paid subscription. That was crushing. Haven't got the photos back up in to that thread.
This thread has a description of the system back then:

This is the long build thread (sucks without photos):

But if you want to see a few pictures of the current state of my room you can see some in a thread I made detailing my building of an isolation platform for my new turntable:

The room remains a compromise, mostly due to my crazy insistence on keeping the home theater and 2 channel systems separate and having the room doing double duty. So the home theater speakers are covered in black velvet along the black velvet screen wall (disappear from view in the dark/no reflective surfaces near the projection screen). My 2 channel speakers are placed well out from the screen wall and placement is quite restricted in terms of back and forth from the seating position due to the fact the speakers can easily block the room entrance.
I think this is where the good room acoustics pay dividends because I can drop speakers - any speakers - right there were you see them in the photo and I get beautiful, smooth, evenly balanced sound from the listening position. The speakers in the above thread are my Thiel 2.7 speakers.
I just bought Joseph Audio Perspective speakers, which are in place of the Thiels. (Though I hang on to the Thiels, as I have other speakers I own, because I like to swap speakers now and then to keep things interesting). The fact that the right floor standing speaker often ends up almost butted up to the end of the sofa has never had any notably deleterious effect on the sound.
We did a drop down ceiling in to which acoustic properties (absorption etc) are hidden, and there is absorption hidden in the screen wall corners, as well as some near the listening sofa. I have a velvet cover that goes over the reflective fireplace near the left speaker, which does a good job of taking away hash/brightness from that reflection point. I also have a diffusor that I'll move around if I need. Also, curtains can be slid along rails to any point in the room, on all walls, so I can control the amount of bare reflective wall to dial in sound. Further, because the projection screen wall is actually a giant velvet 4-way remote controlled masking system, I can dial in the amount of reflectivity by changing the screen size (the more I open up the black velvet masking to reveal more screen, the more reflectivity, the more vivid and airy the sound gets).
Cheers.
