Marrickville Granny Flats Built Around Your Property
Marrickville features predominantly Federation and interwar homes on generous blocks, with many properties offering 450 to 600 square metre lots. These established Inner West blocks typically include deep backyards and side access, making them ideally suited for granny flat construction. The mix of original cottages and renovated family homes provides excellent opportunities for secondary dwellings.
We service all areas of Marrickville and surrounding Inner West suburbs including Dulwich Hill, Stanmore, Petersham, Sydenham, and Tempe. Our team has extensive knowledge of Inner West Council requirements and delivers studio, one bedroom, and two bedroom granny flat designs tailored to the area’s established blocks. We understand the unique characteristics of Marrickville properties and design accordingly.
The Marrickville property market remains strong with median house prices exceeding $1.8 million, creating significant demand for affordable rental options in the Inner West. A quality two bedroom granny flat can achieve $650 to $750 per week in rental income. Building a granny flat now allows homeowners to capitalise on ongoing rental demand while adding substantial value to their property.
