Ok, so after more than two years of permit frustration, I've finally started work on my HT. The room I'm working with was originally 15' x 20'. It was converted from a garage: I decided to add a 16 foot extension to make it a 28 x 20 room, with three feet behind the far wall for an IB sub. Here's the original exterior: http://i188.photobucket.com/albums/z...7/DSCF0498.jpg Framing the addition: http://i188.photobucket.com/albums/z...7/DSCF1667.jpg Here's a view of the framed and insulated addition: http://s188.photobucket.com/albums/z...t=DSCF1676.jpg Here's a view looking towards the entrance and equipment closet: http://s188.photobucket.com/albums/z...t=DSCF1677.jpg I took my inspiration for the basic layout from Art Sonneborn's room. I really like the way he oriented his equipment closet to the entrance. After the contractor is done, a friend of mine who works in construction will help me with double drywalling the walls with GG, building the risers, etc. My plan is for three rows of three chairs. Since I had to wait so long for the building permit, I had lots of time to lay out everything in Autocad. Here's a rendering I did: http://s188.photobucket.com/albums/z...snoambient.jpg I've spent years marveling at the amazing theaters many of you have built. The quality and quantity of information available on this sort of thing is truly remarkable, and I look forward to the day when I can enjoy what many of you have worked so hard to make come true.
