Leichhardt Granny Flats Built Around Your Property
Leichhardt features established homes built predominantly from the 1890s through to the 1960s, with charming Victorian terraces, Federation cottages and post war bungalows on compact inner city blocks. Typical block sizes range from 200 to 400 square metres, with many properties offering rear lane access or side setbacks ideal for granny flat placement. These established blocks suit well designed secondary dwellings that maximise space while respecting heritage streetscapes.
We service all areas of Leichhardt including Leichhardt, Newtown, Marrickville, Annandale, Stanmore and Petersham, delivering studio, one bedroom and two bedroom granny flats tailored to Inner West blocks. Our team has extensive experience navigating Inner West Council requirements, ensuring your granny flat design meets local planning controls and heritage considerations. We specialise in designs that suit narrow blocks, rear lane access and compact urban sites common throughout the area.
Leichhardt’s property market remains strong due to its proximity to the CBD, excellent public transport links and thriving café culture attracting young professionals and families. Rental demand for quality self contained accommodation is exceptionally high, with granny flats achieving $550 to $650 per week depending on size and finishes.
