A granny flat in Narellan costs $150,000–$300,000+ depending on size and finishes. 1-bed from $150K, 2-bed from $200K. CDC fast-track approval in 10–15 business days. Buildana manages design, Camden Council approval and fixed-price construction.
Narellan Secondary Dwellings
A granny flat in Narellan depends on the block, because the suburb is a mix. The older Camden and Narellan streets have 1980s–2000s homes on generous 600 to 900m² blocks that take a studio well, while the master-planned new-release pockets are tighter — so the survey is the honest first step. This is the LGA's main retail and commercial centre, anchored by Narellan Town Centre.
Where a block qualifies, the growth-area demand and amenity make a studio let steadily. The main thing to price properly here is the ground: the western edge carries Class H to E reactive clay, which is highly reactive and demands a properly engineered slab.
The soil is Wianamatta Shale grading M with reactive clay pockets on the western edge, so a stiffened-raft slab — sometimes a deeper footing on Class H–E ground — is engineered off a real geotech. The stock is newer, so asbestos is usually less of a factor.
We build fixed-price, licence HBL 487805C. Survey and reactive-soil geotech scoped first.
Buildana manages the full granny flat process in Narellan — 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.

A mix of blocks
The older Camden and Narellan streets have 1980s–2000s homes on generous 600 to 900m² blocks that take a studio well, while the master-planned pockets are tighter.
The survey is the honest first step, and the growth-area demand makes a qualifying studio lettable.
Reactive clay
The western edge carries Class H to E reactive clay, which is highly reactive and demands a properly engineered slab.
The shale with reactive clay pockets means a stiffened-raft slab — sometimes a deeper footing — engineered off a geotech, and the newer stock rarely carries asbestos.
