I am trying to get some ideas and could do with some help. I am having my home cinema built at the end of the garden and they have got it up to plate. The roof is being done tomorrow (saturday). My next step is to sort out the electrics then decide what i am doing with the walls.(plaster etc). I can't make my mind up whether to plaster the walls or if there is any sort of material i could put on them. The walls are block,cavity and insulation then outside brick. Any ideas or recommendations? I'll be back on tomorrow afternoon to post some pics.
