Sydney Olympic Park Granny Flat Construction — Fixed Price
I'll be straight about a granny flat in Sydney Olympic Park: it's almost never viable, because there aren't the blocks for it. This is a master-planned event and residential precinct on the former Homebush Bay industrial site — R4 high-rise apartment towers built from the 2000s onwards, with no detached housing stock. A secondary dwelling under the Housing SEPP needs a freestanding house on a qualifying lot, and Olympic Park simply doesn't have them.
If you own an apartment here, a granny flat isn't the path — that's an honest answer, not a sales pitch. Where Buildana helps in a precinct like this is other work: interior fitouts and renovations within an apartment, subject to strata approval, rather than a detached studio that the land can't accommodate.
The site itself is reclaimed alluvial and Wianamatta Shale with heavy industrial-legacy contamination management on remediated parcels — another reason the ground here is engineered and controlled, not backyard-buildable.
We build fixed-price, licence HBL 487805C. I'll tell you plainly if your site can't take a granny flat.
Buildana manages the full granny flat process in Sydney Olympic Park — 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.

Almost never viable
Sydney Olympic Park is R4 apartment towers on the former Homebush Bay industrial site, with no detached housing stock — so there's no freestanding block for a secondary dwelling.
If you own an apartment here, a granny flat isn't the path, and I'll tell you that plainly.
Where we can help
In a precinct like this the useful work is interior fitouts and renovations within an apartment, subject to strata approval, not a detached studio.
The reclaimed alluvial and shale site with heavy contamination management is engineered and controlled, not backyard-buildable.

How It Works
From First Call to Final Key
Free on-site assessment of your Sydney Olympic Park property. We measure setbacks, check existing services, assess access, and confirm your N/A (apartment-led precinct) block meets City of Parramatta Council's requirements for a secondary dwelling.
⏱60m² sounds tight on paper but designs well — high ceilings, good cross-ventilation, smart storage, and proper bedroom proportions make a 2-bed feel generous. We design for daily liveability, not just floor plan compliance.
⏱CDC fast-track through a private certifier — typically approved in 10–15 business days. Sydney Olympic Park is zoned R2 Low.
⏱Your granny flat is built from slab to keys in a single programme. Engineered slab for Class M soil, frame, lock-up, fit-out, painting, flooring, and external works.
⏱Defect-free inspection means we don't hand over a list to chase — every snag is fixed before keys move. Final clean, electrical and plumbing tested, smoke alarms certified, BASIX commissioning verified.
⏱Quality Promise
Every Buildana granny flat in Sydney Olympic Park is built under a fixed-price contract with full Sydney Olympic Park council compliance and a 6-year structural warranty.
