All the roads seem to refer to water
I know you said it was a canal (which one is it?) but would worry me that they might be on a flood area as the names of roads quite often give a clue to the area where they are built iyswim
Have you or any friends lived nearby so know what was there 20 years ago or before they were built?
Was it a clay producing pit or whatever they are called where they used to dig to collect clay to make bricks etc?
On the house it seems lovely esp the staircase and double height hallway if you are a fan of new build houses
No idea how it is with the price as I don't know the area but quite a big house
