Cass Property is pleased to offer this rare and compelling opportunity to acquire a substantial amalgamated development site at the gateway to Mount Colah's established medium-density corridor.
Comprising four consolidated lots with a combined site area of approximately 3,468sqm, the holding occupies a prominent corner position at the intersection of Pacific Highway and Willarong Road, offering dual street frontage, strong visibility, and genuine scale rarely available in this tightly held suburb.
The Opportunity:
Zoned R3 Medium Density Residential under the Hornsby Local Environmental Plan 2013, the site offers a clean slate for a significant multi-dwelling development outcome, subject to council approval. The R3 zone permits townhouses and multi-dwelling housing (STCA), providing an astute purchaser with genuine flexibility to optimise the development yield across the combined footprint.
With Pacific Highway corridor sites consistently attracting strong developer demand and comparable developments along this stretch producing outcomes of 14 to 25 dwellings on similar or smaller sites the scale and potential of this holding is immediately apparent.

Lots: 1 Willarong Road & 498, 500, 504 Pacific Highway, Mount Colah
