Chiswick Granny Flats Built Around Your Property
Chiswick features predominantly Federation and Californian bungalow homes built in the early 1900s, set on generous blocks typically ranging from 450 to 650 square metres. These established properties offer excellent granny flat potential with wide side access and substantial rear yards. The traditional layout of weatherboard and brick homes on elevated blocks provides ideal conditions for secondary dwelling construction.
We service all areas across Chiswick, Leichhardt, Newtown, Marrickville, Lilyfield and Five Dock, bringing extensive Inner West council knowledge to every project. From compact studios to spacious two bedroom granny flats, our designs are tailored to suit the narrower blocks and heritage considerations typical of Inner West properties. Our team understands local planning requirements and delivers solutions that complement your established home.
The Chiswick property market remains strong with median house prices exceeding $2.5 million, making granny flats an intelligent investment for homeowners. Rental demand is consistently high given proximity to Sydney CBD, universities and Parramatta Road employment, with granny flats achieving $500 to $700 per week. Building now allows homeowners to generate rental income or accommodate family while adding substantial long term property value.
