Clifton Gardens Secondary Dwellings
A granny flat in Clifton Gardens is an ultra-premium, family-driven build. On 600 to 1,500m² blocks worth $5M to $15M on Chowder Bay and Taylors Bay, a secondary dwelling is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold many times over, so size is never the question.
The site and heritage are everything here. Heritage Conservation Areas cover virtually all streets, so a secondary dwelling goes through a full DA. And the sandstone ground with deep rock excavation typical, plus substantial fall to the water and Sydney Harbour National Park frontage, means engineered slabs, substantial retaining and serious excavation.
So I scope the rock and the heritage first, and design a dwelling worthy of a direct-harbour address. This is architect-led work to the highest standard, from day one.
We build to that standard, fixed-price, licence HBL 487805C.
Buildana manages the full granny flat process in Clifton Gardens — 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.

It's designed to be worthy of a direct-harbour address, answering the main house.
Deep rock and heritage
Heritage Conservation Areas cover virtually all streets, so a secondary dwelling goes through a full DA — scoped first.
Sandstone ground with deep rock excavation, substantial fall and National Park frontage means engineered slabs, retaining and serious excavation off a real geotech.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. Site visit to your Clifton Gardens block to check feasibility — lot dimensions, sewer and stormwater locations, driveway access, and Mosman 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 Clifton Gardens-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 Clifton Gardens construction phase. Fixed price, programmed, supervised. Most Clifton Gardens 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: $800–$1,200/week per week.
