Sites on Blackglen Road, Sandyford, Dublin 18 (-145k, -21%)

Previously listed at 695k (still contained in brochure on myhome) now listed at 550k

Any suggestions how much it would cost to build a similar house to the one described?

These sites appear to have shrunk in size as well as price as the brochure now says:
