    Holroyd Granny Flats Built Around Your Property

    Holroyd features predominantly established homes built from the 1960s through to the 1990s, with generous block sizes typically ranging from 550 to 700 square metres. These spacious blocks provide excellent opportunities for granny flat construction, with most properties offering side access and ample rear yard space. The established nature of the area means mature landscaping and wide street frontages are common throughout.

    We service all areas across Holroyd including Greystanes, Mays Hill, Pemulwuy, Girraween, Pendle Hill and South Wentworthville with expert granny flat construction. Our team has extensive knowledge of Canterbury Bankstown Council requirements and neighbouring council regulations, ensuring smooth approval processes. We design studio, one bedroom and two bedroom granny flats specifically tailored to the generous block sizes typical throughout the Holroyd area.

    The Holroyd property market continues to attract strong rental demand driven by families, essential workers and proximity to Parramatta and Western Sydney employment hubs. Granny flats in the area achieve weekly rental returns of approximately $400 to $500, providing excellent income potential for property owners. With established homes on large blocks and growing demand for affordable housing, now is an ideal time to add a secondary dwelling.
