Hassall Grove Granny Flats Built Around Your Property
Hassall Grove features established homes built predominantly from the 1980s and 1990s, with many properties sitting on generous blocks ranging from 550 to 700 square metres. These larger block sizes provide ample space for a secondary dwelling while maintaining comfortable outdoor areas. The typical single storey brick homes and wide side access make Hassall Grove properties ideal candidates for granny flat construction.

Our team has extensive knowledge of Blacktown City Council requirements and approval processes, ensuring smooth project delivery. We design studio, one bedroom and two bedroom granny flats specifically tailored to the block dimensions and orientation typical of this established residential area.
