    Anyone got a recommendation for building firms in Norfolk to deal with building works for a garage conversion including sound proofing walls / ceilings / etc?

    I have no specific recommendations for builders for you to try. But I would recommend you go through the normal way of selecting a builder, normal recommendations, seeing their work first hand, asking Building Control. It’s not a particularly big job for any builder.

    What I think will be more important, is for you to guide them in what is required. Understanding the principles yourself, and working closely with your builder to deliver these. It would be good if you can get a builder who is prepared to look into it to.

    If you look for a specialist, that may come with more premium design costs, when it should be (the right) material and extra labour only really.

    Sound proofing is difficult in respect of you don’t know where to draw the line, and whether it is all worth it until it’s too late. You only get one chance, but where do you put the emphasis?

    Mass, absorption, isolation or damping? Some of all of these would be the start point....

    Thanks @wl1; all very good advice.
    I'm not planning on going ear-splittingly loud - not interested in ruining my ears - and the room mostly adjoins the neighbour's lounge and our hallway, though we have my son's bedroom above and their lounge is above their garage, so I certainly don't want to be a nuisance.

    I converted my garage to a playroom a while back, and part of it was single skin brick. My BCOfficer advised what I would need to meet minimum requirements, but as it was DIY I think he allowed more flexibility than you might get away with professionally. It is defo worthwhile speaking with them, invaluable (free) advice.

    It is still one of the colder rooms in the house but that doesn’t stop it getting used. A cinema room is likely to get warmer with the equipment - unless you have a cunning plan.

    My other experience of Sound Proofing was my outside dedicated building. Not really applicable to you, but I selected offset 4x2 in the stud wall as isolation, with Soundshield plasterboard for mass, green glue as damping between another layer of Soundshield plasterboard, plus Rockwool between the timbers for absorption.

    I am really impressed with the results.

    Weak points for you to consider will be the ceiling, electrical outlets and doors.

    Thank you very much @wl1 - call to building control is the very next thing on my list. None of my walls are single skin and the most obvious wall they could have skimped on insulation (between mine and my neighbours garage) has insulation, so I am hoping for good news.

    I'm very intolerant of hot so I am quite likely to have Ac installed (already there upstairs)

    Not knowing what space you have internally, ill assume its a single car garage.

    I would create an internal frame inside the garage with wooden battens, you can run your cables behind it and put sound poof panels on top. You wouldn't lose much internal space.

    On your ceiling you will have joists (pitched roof) so there would be no need to put a frame there, again put the sound proof panels on the roof.
