AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch uses VIC State Government's Regional/LGA projections from 2023, adjusted using weighted aggregation methods to SA2 levels. Growth rates by age group are applied across all areas for years 2032 to 2041. Future population trends indicate an increase just below the median of national areas, with Sydenham expected to expand by 1,218 persons to 2041 based on latest annual ERP population numbers, reflecting a total increase of 9.8% over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Sydenham, placing the area among the bottom 25% of areas assessed nationally

Sydenham averaged approximately 41 new dwelling approvals annually from FY21 to FY25, with a total of 206 homes approved during this period. As of FY26, 2 dwellings have been approved so far. The population has declined in recent years, suggesting that new supply has kept pace with demand, providing good options for buyers.

The average expected construction cost value of new homes is $223,000, which is below regional levels, indicating more affordable housing choices. In FY26, $5.8 million worth of commercial development approvals have been recorded, reflecting the area's residential character. Compared to Greater Melbourne, Sydenham has shown moderately higher new home approvals, with 16.0% above the regional average per person over the past five years. This balance between buyer choice and support for property values is notable. However, building activity has slowed in recent years, which could be attributed to the area's maturity and potential planning constraints. New development in Sydenham consists of 24.0% detached houses and 76.0% townhouses or apartments.

This shift towards denser development caters to downsizers, investors, and entry-level buyers, reflecting decreasing availability of developable sites and changing lifestyles. The current housing stock is predominantly houses (66.0%), indicating a notable change in new developments. There are approximately 3091 people per dwelling approval in Sydenham, demonstrating an established market. According to the latest AreaSearch quarterly estimate, Sydenham is expected to grow by 1,182 residents by 2041. With current construction levels, housing supply should meet demand adequately, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
