Granville Granny Flat Construction — Fixed Price
Not every street in Granville plays by the same rules, and a granny flat quote should reflect that. The suburb carries a heritage precinct where external changes face extra scrutiny, alongside ordinary R2 and R3 streets where a secondary dwelling on a 450 to 700m² block is about as straightforward as Sydney gets. Knowing which street you are on is step one, and it is free to find out.
The fundamentals are strong either way: your own station on the T-Way into Parramatta, renewal money flowing through the town centre, and rents of $400 to $530 a week from a deep tenant pool. On the 1920s to 1960s housing stock, most backyards have the depth.
What I would check first on a Granville block: whether it sits in the heritage precinct, the zoning, and the backyard depth. Those decide the pathway.
We build these fixed-price, licence HBL 487805C. We will confirm your zoning, your heritage status and your siting in one visit.
Buildana manages the full granny flat process in Granville — 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.

Which street are you on?
Granville carries a heritage precinct where external changes face extra scrutiny, alongside ordinary R2 and R3 streets where a secondary dwelling on a 450 to 700m² block is about as straightforward as Sydney gets.
So the quote depends on the street, and knowing which one you are on is step one. It is free to find out, and it decides the whole approach.
Strong fundamentals either way
The fundamentals hold either way: your own station on the T-Way into Parramatta, renewal money flowing through the town centre, and rents of $400 to $530 a week from a deep tenant pool.
On the 1920s to 1960s housing stock, most backyards have the depth. Send us the address and we will confirm the zoning, heritage status and siting in one visit.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Assessment is the most important hour you'll spend on the project. Get the position, orientation, and access right and the build runs clean. Get them wrong and you're chasing certifier RFIs for months. Buildana checks every constraint before recommending a position. We design your granny flat to maximise the 60m² allowance within Cumberland City Council's setback and POS requirements. Floor plan, elevations, and 3D render provided. Studio, 1-bed, or 2-bed configurations available.
⏱The Granville construction phase. Fixed price, programmed, supervised. CDC pathway exists specifically for compliant granny flats — use it. No neighbour notification, no Cumberland City Council planner queue, no committee politics. Certifier checks the design against the code; if it complies, it approves. 10–15 business days, every time. Fixed-price build: slab (Class M engineered), frame, roof, fit-out, connections. 10–16 weeks depending on size. Minimal disruption to your existing home.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Walk through your finished granny flat, collect keys. Occupation Certificate, 6-year structural warranty, and maintenance guide provided. List for rent immediately — typical demand in Granville fills vacancies fast.
⏱Quality Promise
Our Granville granny flat builds run on CDC fast-track where eligible. 10–15 business days to approval, 12 weeks to handover, fixed price.
