    Ermington Granny Flats Built Around Your Property

    Ermington features predominantly brick homes built from the 1960s through to the 1990s, situated on generous blocks typically ranging from 550 to 800 square metres. These established properties offer excellent street frontage and deep backyards, making them ideal candidates for secondary dwellings. The relatively flat terrain and mature landscaping provide perfect conditions for granny flat construction.

    We service Ermington and surrounding suburbs including Rydalmere, Dundas, Melrose Park, Carlingford, and Telopea with expert granny flat design and construction. Our team has extensive knowledge of Parramatta Council requirements and planning regulations specific to this area. We offer studio, one bedroom and two bedroom designs tailored to the generous block sizes typical of Hills district properties.

    The Ermington property market remains strong with excellent proximity to Parramatta CBD and major transport links driving rental demand. Granny flats in this area typically achieve $450 to $550 per week, providing solid returns for homeowners. With ongoing housing affordability pressures and families seeking multi generational living solutions, now is an ideal time to add a secondary dwelling.
