By this I don't mean "keep the water out" as I suspect that this is actually
very hard to achieve. I'm thinking more of waterproof non-absorbant walls
(possibly tiled) downstairs, all electricty cables coming from upstairs (or
from the loft) *down* rather than from under the floor up, solid concrete
floors downstairs and maybe even a floating "raft" floor on top of the
concrete floor for your furniture that would float on top of flood waters
keeping your valuables dry.

Wonder how *fast* the water comes in in situations like this? i.e. would
concrete floors and a drainage channel around the perimeter, leading to a
sump/pump do the job - or would the pump just get overwhelmed? (There's
the issue of where to pump *to* of course!)
