The Jessamine Avenue Urban Conservation Area has significance as a remarkably cohesive and intact 1920s-40s precinct resulting from the development of the large mansion estates and containing an impressive grouping of substantial houses set in landscaped grounds and streetscapes of the period.
The key heritage characteristics of the Jessamine Avenue Urban Conservation Area are:
. as an expression of a singular estate and sub-division design with a coherent street character created at the point of subdivision and reinforced by the development period of the houses
. the Ash and Liquidambar street tree plantings set within wide grassy verges in Jessamine Avenue
. the curved concrete roadways of Jessamine Avenue and Linden Court
. the large upper middle class two storey houses each of a distinctive character but collectively reflecting the styles and tastes of the inter-war period
