    Kirrawee Granny Flats Built Around Your Property

    Kirrawee features predominantly established homes from the 1970s and 1980s, with generous block sizes typically ranging from 550 to 700 square metres. These larger blocks with side access make them ideal for granny flat construction, offering ample space for a secondary dwelling without compromising the main residence. The established nature of properties presents excellent redevelopment opportunities for homeowners seeking to maximise their land potential.

    We service Kirrawee, Gymea, Sutherland, Kareela, Miranda and Jannali with expert granny flat construction tailored to your local block. Our team has extensive knowledge of Sutherland Shire Council requirements and can design studio, one bedroom or two bedroom granny flats that suit the established housing stock throughout the area. We ensure every design maximises your available space while meeting all local planning controls.

    The Kirrawee property market continues to strengthen due to proximity to train stations, quality schools and the Westfield Miranda shopping precinct. Strong rental demand from families and professionals means granny flats can achieve weekly rents of $450 to $550 for a one bedroom dwelling. Building a granny flat now allows homeowners to capitalise on infrastructure improvements and growing population in this St George corridor.
