Hi I am considering converting my garage into a cinema room and would be grateful if anyone could offer any advice as the optimum size for this. I have a single garage which currently measures 5.1m long x 2.5m wide. My initial thoughts are that the length would be disproportionate to the width so was considering creating a store to one end of the garage, thus creating a cinema room of 4.0m long x 2.4m wide (see sketch), would this size be okay?
