A granny flat in Roseville Chase 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, Ku-ring-gai Council approval and fixed-price construction.
Granny Flats Designed for Roseville Chase Blocks
A granny flat in Roseville Chase is a premium, harbour-driven build. On 700 to 1,400m² blocks on Middle Harbour worth $3M to $5.5M, a secondary dwelling is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold with room to spare.
The site is the whole story here. Class M soil with sandstone outcrops, and on the water-fall lots a significant drop to the harbour that calls for suspended slabs and substantial retaining — serious engineering that has to be scoped off a real geotech before anything else. Heritage controls also apply on the older inland streets.
So I scope the site engineering and any heritage first. The harbour setting drives prices well above the Ku-ring-gai average, and a second dwelling has to be built to that standard.
We build to the standard the address demands, fixed-price, licence HBL 487805C. Site and heritage scoped before design starts.
Buildana manages the full granny flat process in Roseville Chase — 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.

Harbour-driven, premium
On 700 to 1,400m² Middle Harbour blocks worth $3M to $5.5M, a Roseville Chase secondary dwelling is guest accommodation, a studio or multigenerational space — the lot clears the 450m² Housing SEPP threshold with room to spare.

Serious site engineering
Class M soil with sandstone outcrops, and on the water-fall lots a significant drop that calls for suspended slabs and substantial retaining — scoped off a real geotech before anything else.
Heritage controls apply on the older inland streets, so I check those early too.

How It Works
From First Call to Final Key
Everything that has to be right before we touch the ground. We inspect your Roseville Chase block — lot size (typical 700–1,400m²), setbacks, services, access, Class M soil check and Ku-ring-gai Council requirements. You'll know if a granny flat is feasible before spending a dollar. Design phase covers layout, orientation on your Roseville Chase block, bathroom and kitchen placement, natural light, privacy screening, and entry path. You approve the design before we move to certification.
⏱The Roseville Chase construction phase. Fixed price, programmed, supervised. Approval pack lodged with our preferred private certifier (Buildana works with several across the Ku-ring-gai area). They've reviewed our designs before, know our documentation standard, and turn approvals around at the fast end of the legislated window. Construction runs 10–16 weeks from slab pour. Class M engineered slab, timber or steel frame, Colorbond roof, full internal fit-out, and separate service connections. Weekly updates from your project manager.
⏱The job isn't done when the site's clean; it's done when you have keys, certificates and warranties. Handover documentation includes everything you need to list with a property manager: OC, BASIX, structural cert, appliance manuals, separate metering details. Photos for the listing taken before furniture goes in. Most Roseville Chase GFs lease within 2 weeks.
