Building Granny Flats in Artarmon
A granny flat builder in Artarmon works with a tight residential grid — Federation, inter-war and post-war stock on 450 to 700m² blocks. Many clear the 450m² Housing SEPP threshold for a 60m² secondary dwelling, but the smaller lots sit right on the line, so the survey is the honest first step. Artarmon station makes a well-built studio or secondary dwelling genuinely lettable here.
Heritage is the second check. Heritage Conservation Areas cover Hampden Road and parts of Cleland Road, so a secondary dwelling in those pockets usually goes through a full DA rather than the fast CDC path. Elsewhere the standard controls apply.
The soil grades Class M on the ridges and tips into H to E down the Middle Harbour valleys, so the slab is engineered off a real geotech to suit. The post-war stock can carry fibro, so a licensed asbestos strip-out leads where any demolition is involved.
We build fixed-price, licence HBL 487805C. Survey and heritage scoped first.
Buildana manages the full granny flat process in Artarmon — 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.

Station-close, survey first
Artarmon's 450 to 700m² blocks mean many clear the 450m² Housing SEPP threshold, but the smaller lots sit right on the line — so the survey is the honest first step.
Artarmon station makes a well-built studio or secondary dwelling genuinely lettable, which is rarer on the north shore.
Heritage and valley soil
Heritage Conservation Areas cover Hampden Road and parts of Cleland Road, so a secondary dwelling there usually goes through a full DA rather than CDC — I check that first.
The soil grades M on the ridges and H to E down the valleys, so the slab is engineered off a geotech, and the post-war stock can carry fibro requiring a licensed strip-out.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Site visit to your Artarmon block to check feasibility — lot dimensions, sewer and stormwater locations, driveway access, and Willoughby City Council's setback and landscape requirements. Written feasibility report within 3 business days. Design pulls from a library of plans we've refined over years of Artarmon-area builds, then adapts to your specific block constraints. Faster than starting from scratch, better than buying a stock plan that doesn't suit the site.
⏱The Artarmon construction phase. Fixed price, programmed, supervised. Most Artarmon granny flats qualify for CDC — faster and simpler than DA. Buildana prepares all documentation, lodges with the certifier, and obtains the Construction Certificate. Typical turnaround: 2–3 weeks. Construction in your back yard means coordinating site access, material delivery, and trade movement around the existing house. Buildana plans the build to keep main-house disruption to a few hours per week, not constant noise and dust.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Final inspection, Occupation Certificate, keys, and maintenance guide. Ready for tenants or family. Rental potential: $650–$850/week per week.
