Thanks guys, i am not sure if he will even ask but i thought i might get a bit of an idea before we organise everything, the house prob wont be built for another 6-12mths anyway and our fences wont be going up until after it's all done (well most of it anyway.

He obviously has the cash as he just spent $130,000 to buy a 1/4 acre to extend his backyard, apparently he has been there a while and is quite nice and knows most of the ppl in the estate.
He might have wanted it done before we build so less noise/dust etc.

Am hoping he doesn't ask but if he does then will have to see what we can afford, we can't afford half of colorbond that wasn't our choice. Personally i wanted 4 nice wood fences around my house... oh well.. compromise is best.

Thanks again.
