I was qutoed approx £4000 for the whole thing to be built, which
wouldsupposedly hold 7000 gallons The pond would be a little different from
typical liners or moulds, as Iwanted a porthole style window in the raised
wallDoes anyone think this price is too high too low or just right based on
their experiences,

That sounds like fun!! I don't know from prices since I built my own.....7000
gallons is a real nice size. Don't get all excited and fill it full of fish.
Take your time adding a few at a time and only get the ones that are really
special to you.....Do you plan on having goldfish and plants or just koi in it?
