Del Oro

Architecturally, although altered, the street view of this house still provides a significant architectural contribution to the city and its ornamentation is distinctively of the area. As a prominently sited and large structure, it is a major element in the valuable Quarry Hill residential precinct. 

Landscape - the garden in its present form is of no historic significance but contributes to the house as a setting. 

Historically, the house has a long association with the Crawford family and particularly George Crawford, who epitomises the self- made entrepreneur who accumulated wealth from both the goldfields and his trade. His recognition by public organisations and government is a further indication of his significance.
