A granny flat in Neutral Bay 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, North Sydney Council approval and fixed-price construction.
Neutral Bay Secondary Dwellings
Let's be straight about a granny flat in Neutral Bay. This is a dense lower-north-shore village of apartments, townhouses and pockets of detached Federation and inter-war stock on 300 to 550m² blocks. So a detached secondary dwelling is only occasionally viable, and the survey plus heritage check is the honest first step.
Where it works is one of the pockets of freestanding housing at the larger end, outside the Hayes Street and Wycombe Road heritage areas, that clears 450m² with genuine rear-yard room. On those, a studio near Military Road and the North Sydney CBD is a real asset — but it's the exception, not the norm.
The ground is sandstone on the ridges, tipping into H to E on the harbour fall, so the slab is engineered off a real geotech. The old stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. I'll tell you honestly whether your block stacks up before you spend on design.
Buildana manages the full granny flat process in Neutral Bay — 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.

Often marginal, sometimes viable

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