I'll be honest about a granny flat in Newtown: on almost every block it won't work. This iconic King Street suburb is wall-to-wall Victorian terraces on tight 100 to 250m² blocks, with Heritage Conservation Areas covering virtually the entire suburb — knockdown-rebuild is precluded and restoration or extension is the dominant scope. There's simply neither the land nor the planning latitude for a detached secondary dwelling on the terrace stock.
Where there's any prospect at all, it's a rare freestanding cottage on one of the larger lots, via a carefully argued heritage DA for a discreet studio — but on Newtown's block sizes that's very much the exception. On a terrace, the realistic scope is restoration and a rear addition, not a granny flat.
The soil is Wianamatta Shale grading M, so any footing is engineered off a real geotech. The old stock frequently carries fibro in later additions, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. I'll tell you honestly and quickly whether there's anything to pursue.
Buildana manages the full granny flat process in Newtown — 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
Newtown is wall-to-wall Victorian terraces on tight 100 to 250m² blocks with heritage over virtually the entire suburb — KDR precluded, restoration and extension the dominant scope.
There's neither the land nor the planning latitude for a detached secondary dwelling on the terrace stock — I'll tell you plainly.
The rare exception
A rare freestanding cottage on a larger lot could take a discreet studio via a carefully argued heritage DA, but on Newtown's block sizes that's the exception.
The Wianamatta Shale grading M means any footing is engineered off a geotech, and old stock carries fibro.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Free on-site assessment of your Newtown property. We measure setbacks, check existing services, assess access, and confirm your 100–250m² block meets Inner West 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.
⏱The Newtown construction phase. Fixed price, programmed, supervised. CDC fast-track through a private certifier — typically approved in 10–15 business days. Newtown is zoned R1/R2 General/Low. Construction Certificate issued before works start. 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. Quality inspections at every stage.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. 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. The unit is rental-ready, not project-paperwork-ready.
