Ashfield Granny Flats Built Around Your Property
Ashfield features predominantly Federation and Californian bungalow homes on generous blocks of 450 to 650 square metres. These established properties offer excellent rear and side access, making them ideal for granny flat construction. The typical deep block layout provides ample space for a secondary dwelling while maintaining the character of the main home.
We service Ashfield and surrounding Inner West suburbs including Leichhardt, Newtown, Marrickville, Summer Hill, Haberfield and Croydon. Our team has extensive knowledge of Inner West Council requirements and designs granny flats specifically suited to the area’s heritage overlays and established streetscapes. From studio layouts to full two bedroom dwellings, we deliver quality builds tailored to your block.
The Ashfield property market remains strong with median house prices exceeding $1.8 million, driving demand for rental accommodation. Granny flats in the Inner West command weekly rents of $550 to $750, providing excellent returns for homeowners. With Sydney’s ongoing housing shortage and Ashfield’s proximity to the CBD, now is an ideal time to add a secondary dwelling.
