Granny Flat Builder in Auburn
Auburn features generous block sizes that support granny flat construction, with R2 and R3 zoning throughout residential areas. Cumberland City Council allows secondary dwellings up to 60m² on eligible lots via CDC fast-track approval. Auburn's proximity to Parramatta and strong rental demand make granny flat investment here particularly attractive — studio and 1-bedroom configurations are especially popular with tenants.
Buildana manages the full granny flat process in Auburn — from site assessment and CDC fast-track approval through to fixed-price construction and handover. We build studio, 1-bedroom, and 2-bedroom designs up to the NSW maximum of 60m².
