Fisherman's cabane

I'm making the most of the good weather before our return to the UK and getting the rides in on the bike (602km in the last 4 weeks).
There are lots of these fishermen's cabanes perched on stilts along the Gironde estuary. Often they have their fishing nets, or carrelets slung out on poles above the water in front of them like this.
They seem to be sought after, as when one comes up for sale, they are soon snapped up - and probably for a silly price.
