Hi all,
My wife finally parted with a portion of her terrace garden and let me build a home theater.
First off all I find myself very fortunate to build a room that can be dedicated to music listening and watching movies. The room will be 3.96 meters wide, 7.38 meters long and a height of 2.7 meters. So with a little more than 29 m2 it's not a big room at all.
We live in a duplex penthouse (5th & 6th floors with terrace rights). So, traditional construction methods are a bit difficult. I plan to take the prefab route.
Proposed HT Room area.
Columns set and trusses on.

An externally hosted image should be here but it was not working when we last tested it.
These pics are of the composite decking sheet being fixed... in fact today... the plasterers were skimming the walls and pouring the concrete slab...
Thanks Pano,
Started laying electrical, speaker and signal cables. The cabling work is being carried out by a local guy and someone from my work giving him a hand.
To reduce hum and noise I want to install a dedicated line with only a single ground from the audio / home theater system to the electrical service panel. Don’t want to attach anything other than the A/ V system to this special dedicated line.
Expecting the result to be noise and hum free power with a 'deep black background'.
By this stage of the project, I have already identified the following:
• Placement of all speakers
• Placement of A/V components
• Placement of video source
• Lighting needs
• Possible future enhancements
• Thermal Insulation & Acoustic Treatment
BTW I have provided a frame also…for supporting the screen.
I will try and post pics if there's interest...as soon as i work out how to do it....!!
I have all the kit I need already for this…mix of new and from old lounge... not top end by any means...but works for me...

What a fantastic, exciting project! Have you given any thought to how you will inaugurate the new room?

Framing work in progress for rock wool slabs…
Checking out my old screen…

Framing work completed and AV cabinet in place….cabling almost done but for one sub signal cable. Got 20 Rock wool bags delivered yesterday.
There was a leak from one point of the slab joint side…. getting the pressure grouting done today.

Slow progress, but progress nonetheless. Tough to get things done when you are on carpenter’s schedule, but I'm grinding along. Got most of the ceiling done, preparing bass traps and acoustic panels…
Nice going! I know, from experience, how much time and work that all is. You will be rewarded by your efforts, that you can be sure of. 
Getting the room right is more than half the battle.

Look thru your photos again I notice a lot of peg board - perf board over the rock wool. Do you think this will have a narrow range of absorption? Thinking like a peak around 1Khz.
The hard walls of the room will need a lot of midrange absorption, just wondering about the bandwidth. What are your thoughts?

Pegboard is a common and effective solution... perforated hardboard with rock/mineral wool behind it was used as some kind of acoustic transparent protection over absorption material. This seems to have just the right absorption for my needs... but it will not works well for early reflection damping.
It act a bit as a combined Helmholtz and membrane damper in such applications, and partly reflective for high frequencies.
Common pegboard is usually used in mid traps rather than bass traps. For example, pegboard with 3/16-inch holes on a one-inch matrix has a perforation percentage of 2.75 per cent.
I have set up basic audio, and I am very happy with the acoustics.
Hey guys!
Here is an update on the build… I have spent countless hours on there reading and learning since I started trying to figure out what I wanted to do 6 months ago. It’s like a fun project for me... The entire room needs a good deal of sound work. Even still, I'm happy with how it sounds to my ears after watching a couple movies... I just need to contain it better for now.
It's the old saying of "measure twice, cut once"… live it, learn it, love it the downside to that is since I have never done anything like this before who knows what I missed or what I underestimated on.

After a long gap... here is an update.
The past few months I've been gathering some more things to move forward. Here are a few goodies that were dropped off:
Video:
Panasonic DMP-BDT 360GA
DUNE HD MAX
Sony Playstation 3 (500GB)
Projector: Panasonic PT-AE8000U Full HD 3D Home Theater Projector
Screen: Screen Research 165” diagonal AT woven custom frame
Electronics:
Pre Processor: Sherbourn PT-7020A preamp processor
Power Amps: DIY TDA7293 based parallel design
I decided to try out tactile transducers for my home theater. Spent a lot of time researching and reading feedback from users and forums.
Ended up getting two of these,
Screen frame assembly:
Grommets eyelets and Bungee tension ties:
Here is a trial fitting and assembly of the screen frame...
This is how my existing screen looks:
