Tregear Granny Flats Built Around Your Property
Tregear features predominantly brick homes built from the 1960s through to the 1980s, sitting on generous blocks typically ranging from 550 to 700 square metres. These established properties offer ample side and rear access, making them ideal candidates for secondary dwellings. The flat terrain and spacious backyards provide excellent opportunities for granny flat construction without compromising existing gardens or outdoor areas.
We service Tregear and surrounding suburbs including Blacktown, Rooty Hill, Quakers Hill, Mount Druitt and Dharruk with a full range of granny flat designs. Our team has extensive experience working with Blacktown City Council requirements and approval processes. We tailor every design to suit the generous block sizes typical of this area, maximising space and functionality while meeting all compliance standards.
Tregear’s affordable property market and strong rental demand make granny flats an excellent investment for local homeowners. The suburb’s proximity to Blacktown CBD, schools and transport hubs drives consistent tenant interest, with quality granny flats achieving around $350 to $400 per week. Building now allows you to capitalise on this demand while adding long term value to your property.
