Lane Cove Granny Flats Built Around Your Property
Lane Cove features established homes predominantly built between the 1950s and 1980s, with generous block sizes typically ranging from 600 to 900 square metres. These spacious North Shore properties offer excellent rear yard access and side setbacks, making them ideal candidates for secondary dwellings. The traditional layout of these homes usually includes deep backyards with mature gardens, providing ample space for a self-contained granny flat.
We service Lane Cove, Lane Cove West, Linley Point, Longueville, Greenwich and Northwood with expertly designed granny flats tailored to North Shore properties. Our team has extensive knowledge of Lane Cove Council requirements and specialises in studio, one bedroom and two bedroom configurations that complement established homes. We design each granny flat to suit your block’s unique dimensions and maximise rental or family accommodation potential.
Lane Cove’s premium North Shore location and excellent schools drive strong rental demand, with granny flats commanding around $600 to $750 per week. The established housing stock and larger block sizes make this suburb particularly suitable for adding secondary dwellings that boost property value. With limited new housing supply in this tightly held area, building a granny flat now positions you to capitalise on consistent tenant demand.
