Hello all. I am just about to start work on converting my detached garage to a dedicated Home Cinema room but thought I'd get some advice from all of you who have already started/completed the projects. Here is the picture as the garage stands from outside. and currently the mess that is inside. (Bookcases aka DVD storage ) My initial questions are should I really look at removing the roof and making it flatter. I was thinking it might suit the acoustices better sloped and the projector will be lower the further I move it back. I was kind of planing to stud, fill with rock wool and plaster board the walls. I was hoping to insulate the 8" roof joists and plaster board that too. Dimensions of the garage are: 6m long by 3m wide. Height 2.7 sloping to 2m. Currently I am looking at bricking up inside the Garage door and having a fixed screen of about 80" diag with a projector (prob the Sanyo Z2 subject to a demo). As you can see from my sig I have a number of speakers but still no AMP yet. Any advice at this early stage would be appreciated.
