I'm finally getting underway making my cabinets on our new (1880) home having completely demolished the previous kitchen. What I've learned is that the house is all earth floors with quarry tile (or suspended timber in other rooms) and solid 9" brick walls with lime plaster (4cm thick in some places!). The kitchen back wall where I want to put cabinets is partially underground and thus pretty damp (damp to the touch most of the time, though not dripping, so presumably air is evaporating). I've learned about the importance of letting water vapour evaporate and have put in a fan that will run 24x7 to keep air fresh. But now I'm wondering how I should install the cabinets (which are all 18mm birch ply). I plan to install a dimpled membrane in front of the brick external wall, with battens and probably wood wool boards with lime plaster on them, with cabinets in front of that. I gather that putting in a timber plinth on the floors would probably be unwise, so will need to have some kind of feet. Any recommendations? should I leave an air gap below? And how should I fix to the wall? Was thinking a french cleat, but wondering if I should minimise contact to ensure evaporation can circulate...
