KDR "building site" - chances of asbestos & getting rid of bulk concrete

This may not be quite the right part of the forum to ask this question ... however the context of our search is "building a new house", issue is there's an existing house which we'd likely be living in for a couple/few years ...
... before Mr Bulldozer comes to visit.

Which will probably be a bit of a shame because it's a double-brick home with quite a bit of room, and from what I can tell double-brick was starting become a lot less common by the late 80's and hence it's likely this place had a bit of money & thought put into it.

Anyhoo, the place we're considering is in Sydney (New South Wales not Nova Scotia), and from council aerial photos it was built some time between 1987 and 1994. It's double-brick construction.

Would I be right in thinking that if it does have asbestos in building materials, it'll be relatively minimal? Stuff like eaves and not much else?

Also is it a massive cost in terms of house-building to get rid of swathes of concrete?
Yes this house has columns as well as Juliet balconies with ornate metal-work at the front ... and apart from an old veggie/fruit garden at the very rear, the majority of the back yard is concrete. Having only paid for one house demolition, and it only having had a short driveway (the front 2/3 of which was two strips of concrete with grass in the middle), I was wondering whether THAT much concrete adds a lot to demo costs? And is double-brick a lot more than wood-frame with vinyl-cladding like our old place?
