Hi Juanita

The architect is BGD Architects. I don't have the exact specification but an old magazine article states that the stone was supplied by International Sandstone The project was completed in 2007 so I am not sure if the supplier is still around.

Looks like traditional Sydney or Hawkesbury Sandstone. Very pricey but the best. I’ve just had some pavers cut to size here in Qld.
