A granny flat in Busby 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, Liverpool City Council approval and fixed-price construction.
Busby Granny Flat Construction — Fixed Price
The payback maths on a granny flat in Busby is hard to argue with. Land runs $700K to $900K, blocks sit at 500 to 650m², and a two-bed secondary dwelling rents for $380 to $500 a week, a yield most inner suburbs cannot get near. With 1960s to 1980s homes approaching end-of-life across the suburb, plenty of backyards are doing nothing.
One thing decides whether your quote holds: the soil. Class H reactive clay moves with the seasons here, and a slab that is not engineered for it will crack within years. Every Buildana price includes the geotech report and the engineered slab from day one.
What I would check first on a Busby block: the reactive-clay slab design, the backyard space and setbacks, and CDC eligibility. Those decide it.
We build these fixed-price, licence HBL 487805C. Send your address through and we will tell you if your block qualifies for CDC fast-track.
Buildana manages the full granny flat process in Busby — 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 yield inner suburbs cannot match
Busby's payback maths is hard to argue with: land at $700K to $900K, 500 to 650m² blocks, and a two-bed secondary dwelling renting for $380 to $500 a week. That yield most inner suburbs cannot get near.
With 1960s to 1980s homes approaching end-of-life across the suburb, plenty of backyards are doing nothing, which is exactly the setup a granny flat rewards.
The slab decides the quote
One thing decides whether your quote holds: the soil. Class H reactive clay moves with the seasons here, and a slab that is not engineered for it will crack within years.
Every price includes the geotech report and the engineered slab from day one, no shortcuts. Send your address and we will confirm CDC fast-track eligibility.

How It Works
From First Call to Final Key
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 Liverpool City Council's setback and POS requirements. Floor plan, elevations, and 3D render provided. Studio, 1-bed, or 2-bed configurations available.
⏱CDC pathway exists specifically for compliant granny flats — use it. No neighbour notification, no Liverpool 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 H engineered), frame, roof, fit-out, connections. 10–16 weeks depending on size. Minimal disruption to your existing home.
⏱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 Busby fills vacancies fast.
