I was extremely disappointed with this site. I do not understand why it got a WHS status. 
Due to it being a private residence no visitors except friends and family of the people that live there can visit. There are no special days to visit. There is not even a sign. It is an ordinary house, surrounded by high fences and gates to keep people out. 

I tried the front doors but nobody was in, so I’m guessing whoever lives here rarely even uses it to live in, as all of the lights were also off. 

There is no way of contacting the owners online, so I truly believe that standing outside to get a picture is likely the best you are ever going to get :(
