Partial integral garage conversion

[jez09uk]

I am planning on converting part of the garage to a habitable room.The garage is integral with bedroom over and cavity wall on one side which was injected with insulation and 100mm block internal wall on the other side which has 12.5mm dot and dab plasterboard on the habitable side. would this this mean that all that would be required for building regs approval would be either dot and dab/or battened plaster board on these two walls?
I would rather use a stud partition wall than blockwork. what would be minimum requirements for stud wall, i.e 100mm timber,foil backed plasterboard,100mm insulation? any info would be much appreciated.

A stud partition wall would require 100mm Celotex between studs with a further 50mm across prior to fixing plaster-boards.

The previous post refers to external walls.

Any internal walls will not require a thermal upgrade provided you are fully upgrading the garage to habitable standards.

Surely not that much?
