sheeting out garage

[livi150]

guys, I am looking to sheet the inside of my garage in plyboard. im not looking to use it for anything apart from a garage, but I just want to insulate it better.

the garage was added onto my semi detatched house after it was built.
the front & back wall are cavity walls, but 1 of the side walls is single breezeblock with a render finish. the other side wall is the wall of the house.

am I right in saying that I can put studs onto the 2 cavity walls and the wall of the house, put insulation then board over it, but what do I do with the single skin breezeblock wall?????? im guessing I need to use a membrame and then insulation??????

there are 4 big went bricks in this wall aswell.

thanks in advance

Heres what i would do.
Stud and insulate the studs. Leave an air gap between the stud. Ensure the gap behind the stud is ventailated on each wall with an airbrick at top an bottom. Board it out.
