Please Help! I am having our basement finished in our newly purchased home and the work is commencing. I have set aside one of the rooms in this basement as our home theatre. It is 17’4” wide X 18” foot room with 9 ft ceiling. At the back of the room there is double sliding door to the outside (not great but it is what it is). The access to the HT will also be at the back of the room on both sides of the room. At the front of the room were the screen will be front there is a duct that protruding down from the ceiling approx 1’ by 1’. We will be extending this 1’ x 1’ around the perimeter of the room.

I would like a small wet bar in the room on the right side when facing the screen.

Please can you provide your ideas to me for screen size, seating location, speaker location, and equipment location etc so I can have the contractors lay the correct wiring in the correct place. Your help will be greatly appreciated.

I think you should squeeze a miniature replica of Stonehenge in there somewhere. It'll be just the right size...

Unfortunately, what you've asked is the type of question that a home theater designer would spend a few weeks and quite a few dollars designing for you. The forum is intended to be a Do It Yourself resource, not a free design center.

My recommendation would be to start reading. Read construction threads from people like SandManX and BigMouthInDC. When you've finished reading those, read some more, then perhaps a bit more. When you've read the first three or four pages of threads you'll know more about home theater and will be in a better position to ask questions that can be answered in less than a few weeks.

If you don't have the time for that I'd recommend you hire a theater designer. Dennis Erskine is one such person on the forums and he may be able to help you.
