Hi, there is later Esri imagery to use and I have redrawn the house shape. Is this house a duplex with part as 
addr:housenumber=1
addr:street=Silvereye Street
and another part fronting Thornbill Street with a different address or is the whole building 1 Silvereye Street.  
If there is another address on Thornbill Street side can you tell me the housenumber.
