Owners on Lincoln Ave hold for 25 years. Edinburgh Rd median hold is 17.9 years. Half the suburb owns outright. The $4.9M median hides three distinct markets: harbour-edge prestige at $6M+, elevated interior at $4.5M, and Eastern Valley Way entry from $2.7M.
The $4.9M median tells you very little. Here is what each price band actually looks like, based on real sales.
The suburb is bounded by Middle Harbour to the north, east, and south, and by Eastern Valley Way to the west. The castle-themed street names (The Battlement, The Rampart, The Citadel) sit on a peninsula jutting into Middle Harbour.
Water frontage or harbour views on the eastern peninsula. Median around $6.1M. 1 Cheyne Walk sold for $6.3M. 13 Cheyne Walk for $6.99M. Longest holds. Low flood risk (elevated). Low bushfire.
The castle-themed streets sit on the peninsula ridge. Median around $4.5M. Griffin-era stone homes, quiet cul-de-sacs. 32 The Scarp sold at $3.41M. Bushfire: moderate (adjacent to reserves).
The commercial corridor with village shops, bus routes. Median $4.9M but wide range ($2.3M to $13M). Highest turnover at 17.9 years. Most DAs concentrate here. Most renovation activity.
Traffic noise from the arterial. Median around $3.5M. Entry point to the suburb. Higher renter share. This is where the proposed 11-storey development sits. 121 Eastern Valley Way and nearby addresses are the most affordable blocks.

Unit-to-house price ratio: Castlecrag units cost 67.8% of house prices. This is a price comparison, not a count of dwellings. Units are proportionally more expensive here than the Sydney median, driven by downsizer demand for limited stock.
Red line = Sydney median (18%). Pool rate from 290 listings with features data (67 mention a pool). Still above median despite heritage constraints limiting pool approvals. Full amenity data in the report.

Castlecrag was designed by Walter Burley Griffin in the 1920s as a community where homes would be "subservient to the setting." The Griffin Conservation Area protects 42 heritage sites. Median floor space ratio is just 0.29 (bottom 4% in Sydney). 24% of the suburb is environmental conservation area.
But the edges are being tested. In May 2025, developer Conquest purchased a corner site at Eastern Valley Way and Edinburgh Road and lodged an 11-storey proposal under the State Significant Development fast-track process. If approved, it would be the tallest building in Castlecrag by a factor of 4.
Recent DAs: lift installation at 335 Edinburgh Rd, deck and cabana at 148 Edinburgh Rd, demolition and new dwelling at 70 Linden Way. Most DAs are alterations, not new builds. Total DA count: 2,140 (top 2% in Sydney).
Castlecrag looks unaffordable. It is not, for the people who live there.
50% of residents own outright. Of the 42% with mortgages, repayments are about 24% of gross income, well below the 30% stress threshold. This suburb has strong vendor holding power in downturns.
The main risk is planning risk. The 11-storey proposal on Eastern Valley Way is the first serious challenge to the suburb's character in decades.
