Mount Colah R3, Development Site

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.
