In terms of mitigating rising damp etc, how did you do that in your own place?

I have a DPC and (mostly) suspended floors. I like my suspended floors (better for the back) and I don't want UFH as it's inflexible to layout changes and not suitable for a house that performs as badly as mine.

If I ever get find the money for a deep retrofit I'll be going down the infill route. It makes no sense to keep suspended ground floors if making major improvements to the rest of the building fabric. Infill gives you better insulation, air tightness, higher ceilings, lower thresholds.
