Why is it significant? Of historic significance, as an example of an interwar housing estate created from the subdivision of a large nineteenth century farm, in this case the Stony Park Estate established by Theodotus Sumner. The subdivision of such estates opened up large parts of Brunswick for development during the interwar period and contributed to a significant growth in population in the first half of the twentieth century. The historic links with the Stony Park Estate, are reflected in the street names, while the southern section of Lowan Street follows, in part, the original coach drive from Glenlyon Street to the Sumner mansion.
