    Dundas Granny Flats Built Around Your Property

    Dundas features predominantly brick homes built from the 1960s through to the 1990s, with generous block sizes typically ranging from 550 to 800 square metres. These established properties offer ample backyard space and side access, making them ideal candidates for granny flat construction. Most homes sit on level to gently sloping blocks with good separation between dwellings.

    We service Dundas, Dundas Valley, Telopea, Carlingford, Ermington and nearby Rydalmere with expert granny flat construction tailored to Hills district blocks. Our team has extensive knowledge of Parramatta Council requirements and works closely with local planners to ensure smooth approvals. From compact studios to spacious two bedroom designs, we create granny flats that complement your existing property and maximise usable space.

    The Dundas property market has seen strong growth driven by proximity to Parramatta CBD and excellent transport links along the T1 Northern Line. Rental demand remains consistently high from young professionals and families seeking quality accommodation near major employment hubs. A well built granny flat in Dundas can achieve $450 to $550 per week, delivering strong rental returns for property owners.
