Gymea Granny Flats Built Around Your Property
Gymea features predominantly brick family homes built from the 1960s through to the 1990s on generous blocks, many exceeding 600 square metres. These leafy streets offer established properties with spacious backyards that are ideal for adding a secondary dwelling. The typical layout includes single or double storey homes with side access, providing excellent potential for granny flat construction.
We service Gymea, Miranda, Kirrawee, Caringbah, Sutherland and surrounding St George suburbs with a full range of granny flat designs from compact studios to spacious two bedroom dwellings. Our team has extensive knowledge of Sutherland Shire Council requirements and approval processes. Every design is tailored to suit the generous block sizes and established garden settings typical of this area.
Gymea’s property market remains strong due to its village atmosphere, quality schools and proximity to Miranda Westfield and transport links. Rental demand is consistently high, with granny flats achieving around $450 to $550 per week. Adding a secondary dwelling now allows homeowners to capitalise on this demand while increasing their property value in this tightly held suburb.
