Inner West Granny Flats Built Around Your Property
Inner West properties feature predominantly Victorian and Federation era homes on blocks ranging from compact 300sqm terraces to generous 600sqm+ freestanding homes. The mix of older housing stock and established gardens creates ideal opportunities for well designed granny flats that complement existing character while maximising site potential.
We build granny flats across Marrickville, Leichhardt, Ashfield, Annandale, Newtown, Petersham, Stanmore and Dulwich Hill, tailoring designs to suit each suburb’s distinct character and council requirements. Our team has extensive experience with Inner West Council’s heritage considerations and planning controls. From modern studios to spacious two bedroom designs, we deliver granny flats that respect neighbourhood character.
The Inner West property market remains highly competitive with strong rental demand driven by proximity to the CBD and universities. Well designed granny flats achieve weekly rental returns of $500 to $750 depending on size and location. Adding a granny flat provides immediate income while significantly increasing overall property value in this tightly held market.
