10 Cowells Lane, Ermington NSW 2115

Duplex approval | 923sqm high side | 4 bed 2 bath | Ermington catchment This property is rare for its size and pre-approved duplex potential, which gives a buyer immediate optionality over a standard family home. The 923sqm lot on the high side with a 19.79m frontage is competitively strong for Parramatta LGA, where similar sites are scarce. The existing 4-bedroom house provides holding income or immediate occupancy, making it suitable for both developers and families who want to defer building. The CDC approval removes the riskiest approval phase, which is a significant time and cost advantage. The main risk is the $2.18m-$2.25m valuation, which already prices in some duplex upside; if construction costs rise or end values soften, margins could compress. The house itself is not a premium finish, so any rental strategy requires realistic expectations around the $955-$1,225pw range. The opportunity is to either develop immediately for capital growth or hold and refinance after the duplex is completed. For a buyer with patience and capital, this is a straightforward hold-and-build proposition.
