To be fair, the room was designed by the architect of the entire house working with constraints including price, land use restrictions, room configurations, etc. I told him I wanted a dedicated media room in the basement and he delivered on that; Neither architect nor I knew anything about or were aware of the acoustically transparent screens, speakers behind the screen, false walls, and all that. My current home theater in my existing house has a non-AT screen with sitting on the floor out in the open and I mistakenly thought that's how most professional home theaters were configured.
The reason the AV rack is in that location in the first place was because there are virtually no other locations available. 3 walls are exterior walls where recessing is not possible and the 4th wall is used up by stairs and machinery room on the other side. The only space available was the crawlspace under the stairs landing which is where the AV recessed cabinet is located.
Would you recommend putting the AV rack on an exterior cabinet near the back? While it won't have that professional recessed cabinet look, at least I will get the AT + false wall + speakers behind AT set-up.
But since this is a new custom project you should set your expectations higher if you want the look and performance of dedicated home theater.
The room has the potential for a really great theater space, your guy isn't getting you there. Contact the Erskine group for their basic design service.
Also now is the time to think about soundproofing, before construction and I suspect there are no plans for that.
I agree with what you said about setting my expectations higher. I did set my expectations higher than my current home theater but they were apparently not high enough, after seeing all the real professional home theaters on the AVSForum. I know I should have researched AVSForum earlier but hindsight is 20/20, I guess. The good news is that the architect is going to incorporate double 5/8 drywalls + Green Glue sandwich for that room so I think some of the soundproofing will be taken care of.
The only issue seems to be the double french doorway entry which someone mentioned would mess up the acoustics or allow sound to leak out. It was suggested that I replace them with a gasketed single solid door. I might go this route if it makes a major difference in the acoustics.
