Peakhurst Granny Flats Built Around Your Property
Peakhurst features predominantly brick family homes built from the 1960s through to the 1990s on generous blocks, with many properties offering 600 to 800 square metre lots. These spacious yards provide excellent opportunities for granny flat construction without compromising existing garden space. The typical property layout includes established homes set well back from the street with wide side access and deep backyards.
We service Peakhurst, Hurstville, Mortdale, Penshurst, Riverwood and Beverly Hills with studio, one bedroom and two bedroom granny flat designs tailored to local block dimensions. Our team has extensive knowledge of Georges River Council requirements and planning guidelines specific to the St George area. We design each granny flat to maximise your available land while respecting the established neighbourhood character.
Peakhurst’s property market has seen strong growth driven by families seeking larger blocks within reach of Hurstville’s shopping and transport hub. Rental demand remains consistently high, with granny flats commanding $450 to $550 per week for one and two bedroom configurations.
