Tahmoor Granny Flats Built Around Your Property
Tahmoor features predominantly established homes built from the 1980s onwards, with many properties sitting on generous quarter acre to half acre blocks. These larger block sizes provide excellent opportunities for granny flat construction, with ample rear yard space and side access typical across the area. The spacious property layouts allow for comfortable placement of secondary dwellings without compromising the main residence.
We service Tahmoor and surrounding suburbs including Camden, Picton, Bargo, Thirlmere, Menangle and Razorback with expert granny flat construction. Our in depth knowledge of Wollondilly Council requirements ensures smooth approvals, while our designs are specifically tailored to suit the larger blocks common throughout outer Sydney.
