Granny Flat Builder in Merrylands

Merrylands' wide blocks from the 1950s and 1960s are well-suited for granny flat construction. Many lots comfortably accommodate a 60m² secondary dwelling while maintaining compliant setbacks, private open space, and landscaped area under Cumberland City Council's controls. Proximity to Merrylands station adds strong rental value — 1-bedroom and 2-bedroom granny flats here attract consistent tenant demand.

Buildana manages the full granny flat process in Merrylands — 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.
