Hi there I'm very shortly going to have my 18ft x 9.5ft garage converted in to a home cinema room, where the garage door is on the front I was going to put a window in (part bricked up part window.! Now I'm currently thinking of going down the projector route and fixing up a 90inch projection screen. With a remote control...... Where the window would be...... However I'm thinking now wether not to put a window in and if I ever moved I would put a window in.....the question is do I legally have to put a window in.? There's 1 door leading to the garage from inside the house from the hallway by the way.! If I can legally put no window in does anyone else have any pics where they have done a similar thing ?
