Why Build a Duplex in Belmore?
Belmore has its own train station and is home to the iconic Belmore Sports Ground. Older housing from the 1930s–1960s on standard blocks provides strong renewal opportunity close to amenities.
Belmore's premium positioning is reflected in above-average construction costs, offset by stronger capital growth and rental returns. Typical residential lots of 500–700m² in Belmore (2192) provide strong building envelopes across a range of project types. Belmore station provides direct rail access. R3 Medium Density zoning in parts of Belmore opens the door to duplexes, townhouses, and multi-dwelling projects — maximising return on your land investment. Class M soil conditions in Belmore are manageable with standard engineered slab design. Median house prices of $1.2M–$1.5M mean land value supports a quality build investment, with granny flat rental potential of $380–$520/week.
Canterbury-Bankstown's R3 zoning in suburbs like Punchbowl, Campsie, Belmore, Wiley Park, and Canterbury provides strong dual occupancy opportunity. Council allows FSR up to 0.85:1 in R3 zones — among the most generous in Sydney. Minimum lot sizes of 600m² apply. Heritage conservation provisions in some suburbs require additional assessment. Buildana manages the complete duplex process from feasibility through construction and subdivision.
