I thought this example might serve to show how something quite simple in theory turns out not to be quite so easy in practice. And because it isn't so easy, the range of stuff and time it takes to overcome.
Angie is a great cook and loves to do it.
The previous owners used bottled gas to run their stove but we didn't fancy the range anxiety (see what I did there..) that goes with guessing when the bottles are about to run out.
So we bought a second hand electric oven for our second hand kitchen and of course this needs power. French wiring regulations dictate a dedicated spur from the board which is fair enough, so off we go..
Jim found a spare circuit breaker of the right size, which was lucky.
I spotted some heavy duty cable up in this barn that wasn't carrying power anymore; ladders, pliers and screwdrivers to get it.
We pushed our cable up through an existing hole but to route it onward meant lifting floor boards in the bathroom. - Circular saw, jemmy bars, torch.
Next barrier the ceiling (SDS core drill sized to make a hole to take the pipe conduit running down) into the utility room.. which is where the route got 'interesting'.
To get from there into the kitchen meant a hole through the wall. No problem, you might think, just drill through. Except this interior wall is made from three feet of mostly, stone.
Getting through took the big drill, concrete breaker, chisels, hammers, muscle, team work and significant reserves of patience to finally get our tunnel. ("Hole" is simply not reverent enough.)
In future this will also carry water and waste pipes plus some more power cables, so it's going to be a busy little tunnel but guessing, I'd say all that took about a day, maybe a bit more.
I'm sure the first meal will taste magnificent.
