If your house is of this construction, there is no practical way to inject/blow insulation into the wall cavity and you are left with the choice of either gutting back to the studs on the inside or removing the exterior cladding and applying housewrap and rigid insulation on the outside.If you do go the interior route, be prepared to encounter hand-sawn timber with substantial variance in dimensions - meaning you will need to shim and plane, or strap, to create a plumb wall for hanging sheet rock {putting back lath-n-plaster would be cost prohibitive and, in our case (a rental), non-compliant with current fire code}.Old buildings can be rejuvenated and made much more efficient, just factor in an additional 10-15% in your reno budget to address any discoveries.

Why I suggested to see if the funds manager had some conduit that would be or could be compliant. :)
