Statement of significance:

This house has individual significance for its aesthetic values such as its earth-bound materials, clinker bricks, shingles and heavy, dark timbers; and also for the way it demonstrates building to suit a difficult site, for its deep setback from Upper Spit Road and its handsome garden, and from the way it demonstrates part of the pattern of architectural style in Australia. It also represents the work of an important Australian architect.

Designer/Maker: James Peddle, for Peddle & Thorp
Builder/Maker: Not known
Physical description: Federation 'American Shingle Style' (McDonald ). This house was on a large site originally facing both Upper Spit Road and Parriwi Road. It is accessed from Upper Spit Road but oriented eastwards to the prospect over Rosherville Slopes, Shell Cove, Middle Harbour, Clontarf and behond to the Heads. 'Sessiagh' is built of clinker brick on a sandstone base, and is partly single-storeyed and partly double-storeyed, with a timber shingle roof having exposed square-cut rafter-feet and purlin ends. Some of the walling is also shingled. Its chimneys are tapered and flat-topped and the exterior joinery is robust, in the California Bungalow manner, but much of the detailing displays Arts-and-Crafts characteristics. The handsome west garden includes mature trees. The eastern part of the original site has been subdivided and now contains another residence.
Modifications and dates: Sympathetic Major Alteration.


Historical notes: 'Sessiagh' was designed by James Peddle in 1915 upon his return from working in California. In that temperate climate, so like Australia's, the California Bungalow was a prominent residential style, and James Peddle was influential in introducing the form to Sydney. It is believed that 'Sessiagh' was designed for May Moore, who was a photographer of note during World War I. A copy of the original drawing by Peddle & Thorp, dated August 1915, survives.
