Granny Flats Designed for Gladesville Blocks
A granny flat in Gladesville sits in the Hunters Hill LGA, and that matters. This village suburb on the Victoria Road spine is Federation cottages, Californian Bungalow heritage and 1960s–1990s brick on 400 to 700m² R2 blocks, with R3 on the Victoria Road precinct. The larger R2 lots clear the 450m² Housing SEPP threshold, so a secondary dwelling is achievable — but Hunters Hill protects its heritage more tightly than almost any council in Sydney.
Heritage Conservation Areas cover several side streets, so a secondary dwelling in those pockets goes through a full DA with close attention to form and materials. Outside the conservation streets it's more straightforward, but the heritage check is the honest first step here.
The ground is Hawkesbury Sandstone bedrock on much of the LGA with Class M shale on the ridge, so rock saw-cutting and engineered footings can apply — scoped off a real geotech. On any river frontage the Foreshore Building Line and Crown Lands referral apply. The older stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Heritage, rock and soil scoped first.
Buildana manages the full granny flat process in Gladesville — 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 Hunters Hill Council's setback and POS requirements. Floor plan, elevations, and 3D render provided. Studio, 1-bed, or 2-bed configurations available.
⏱The Gladesville construction phase. Fixed price, programmed, supervised. CDC pathway exists specifically for compliant granny flats — use it. No neighbour notification, no Hunters Hill 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 Hawkesbury Sandstone bedrock 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 Gladesville fills vacancies fast.
