Kooyong is one of Stonnington's smaller and more exclusive residential pockets, sitting between Toorak and Hawthorn near the Yarra River. The suburb is characterised by substantial Edwardian and interwar housing on generous lot sizes. Amendment C320ston (Toorak, Armadale and Kooyong Heritage Review) materially extended Heritage Overlay coverage in Kooyong, making heritage response a central design consideration for most current development sites.

Common refusal patterns to design around
-
1
Heritage impact on contributory or significant buildings — particularly relevant given C320ston coverage

View source →How successful Kooyong applications typically work
Across recent Kooyong dual occupancy and townhouse outcomes, a recognisable pattern of successful applications emerges. While every site differs, the following observations apply to most viable approval pathways in the suburb.
Site selection patterns
- Lot sizes and frontages consistent with the typical successful configurations described above (in most cases 600–900m² with 15m+ frontage for side-by-side dual occupancy).
- Heritage or character-protected sites consistently proceed via retention of the existing front dwelling rather than full demolition.
- Lots constrained by mature canopy or vegetation typically require design adjustment around protection zones rather than seeking removal.
Design response patterns
- Subordinate scale to the established streetscape consistently expected across Stonnington applications.
- Materials palette consistent with Stonnington's assessment framework — restrained, contextual, considered.
- Front building line matching the prevailing street setback rather than projecting forward of adjoining houses.
Process patterns
- Pre-lodgement consultation with Stonnington materially reduces RFI iteration counts.
- Direct neighbour engagement before lodgement reduces VCAT review risk on applications attracting objections.
- Strongest applications lodge with all required supporting documentation (heritage, arboricultural, bushfire, ESD where applicable) attached at intake.
Tribunal context
Tribunal commentary on Stonnington heritage applications consistently emphasises the council's design excellence threshold. A representative recent matter — including the VCAT consideration of a high-rise residential proposal on Toorak Road, South Yarra (refused on heritage and built-form grounds, reported by Gadens, 2024) — illustrates the Tribunal's deference to council's heritage assessment framework in prestige residential contexts.
These patterns indicate typical successful pathways. Site-specific outcomes depend on the particular planning context, design response, and engagement strategy chosen.
Amendment C320ston materially extended Heritage Overlay coverage across Kooyong. Most contributory sites now proceed via retention plus carefully composed addition — design quality and materials response are consistently the deciding factors.
