Granny Flat Builder in Strathfield South
Measure first, dream second, that is the order for a granny flat in Strathfield South. Blocks in this Burwood LGA pocket run 300 to 550m², which puts a good number under the 450m² SEPP minimum, and the Cooks River alluvial soil on the southern fringe brings flood planning controls that shape what can be built and how high it sits. Two checks, both quick, both decisive.
Blocks that pass earn their keep: $520 to $720 a week, drawn from the same international student and Olympic Park worker demand that feeds Strathfield proper, at friendlier land prices. Federation and post-war homes here often leave more usable yard than the lot size suggests.
What I would check first on a Strathfield South block: the surveyed size against 450m², the flood controls on the southern fringe, and the yard. Those decide it.
We build these fixed-price, licence HBL 487805C. We run the lot measure and the flood search in one pass, free, and usually inside a week.
Buildana manages the full granny flat process in Strathfield South — 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.

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 Burwood Council's setback and POS requirements. Floor plan, elevations, and 3D render provided. Studio, 1-bed, or 2-bed configurations available.
⏱The Strathfield South construction phase. Fixed price, programmed, supervised. CDC pathway exists specifically for compliant granny flats — use it. No neighbour notification, no Burwood 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 Strathfield South fills vacancies fast.
