Two exterior walls in my kitchen were originally part of an outhouse and are only one brick thick. How can I upgrade and insulate these walls and address the damp problem without rebuilding?

personly, i would use 12.5mm insulation backed plasterboard secured to the walsl using dot and dab, most buildiers/carpenters will do it so if you have a reccomended one use them, its not easy to dot and dab correctly (i say correctly as anyone can stick to a wall out of square)
or, fix 2*2 timbers to the wall, fill between with fiberglass/celotex insulation and then plasterboard with 12.5mm plasterboard (put another layer over this one if you want to go belt and braces and have a very strong wall)

Try Fermacell rather than plasterbard as its load bearing and pretty immune to damp.
Remember to use a breathable damp proof membrane behind the insulation (sometimes this is built into the insulation boards) as you want to avoid condensation inside the dry walling.

whatever you do leave an airgap between the wall and applied surfaces and ventilate. dot and dapping will cause problems.
