Insulation

What insulation do I need in my Garage Conversion?

I am converting my garage and hope to do as much internal work myself as possible. 2 walls of the garage are internal and as such attached to 'heated' areas. The 3rd wall is double thickness into nextdoor's garage. Directly above both garages are the bathrooms. i am assuming that seeing as the bathroom walls must be insulated, the garage wall beneath must be similar (not sure how someone might build a thicker wall onto a thinner wall beneath) am i right? What will I need to ensure I don't lose heat? Do I need to insulate the 3rd wall as it is next to an 'unheated' space? Or do I have sufficient insulation already? If I do need to insulate, how much? I obviously want to avoid losing space. With the bathroom above I shouldn't need to insulate ceiling, so it's just that 3rd wall!
