What are you going to use the room for, if it’s for normal music playback like a small home studio or home cinema room, I would say you will need to lose about 6-8inches, 6foot would be nice but it isn’t realistic. You will have to start by re-insolating the existing walls and replace the plaster with more suitable plasterboard!
As far as rough costs go, it’s just too hard to say as if you are going to get someone to do the work the labor will be a huge cost. As you know the rough size of the room you should be able to work out the costs easily by making a couple of calls to plaster companies, lumber yards & insulation companies! You need to be realistic as well as a lot of insulation companies will lead you astray with quotes like “it reduces sound by 80%”… It’s all rubbish, isolation will vary with different frequencies and the weakest link will always be the construction not the products……..
I nice double brick room would be a good start of cause!!!!!
