A knockdown rebuild in Roseville Chase costs $450,000–$1,200,000+. Standard single-storey from $450K, two-storey from $650K. Buildana manages demolition, Ku-ring-gai Council approvals, and construction under one fixed-price contract.
Roseville Chase Knockdown Rebuilds
A knockdown rebuild in Roseville Chase is a premium waterfront project on Middle Harbour — waterfront and water-view blocks running 700 to 1,400m², with prices well above the Ku-ring-gai average. A rebuild here is about designing a substantial home that makes the most of a genuine harbour setting.
The harbour setting brings the main technical work. Many lots have significant fall to the water, which means suspended slabs and substantial retaining rather than a simple slab-on-ground. The ground is Class M with sandstone outcrops, so rock can feature on the substructure. I get a real geotech so the fall, rock and retaining are all priced properly.
Heritage controls apply on the older inland streets, and the pre-war stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition. There is no station here — Roseville is around 2km.
We rebuild fixed-price, licence HBL 487805C. Get our knockdown rebuild feasibility, with the fall, rock and retaining costed, before you commit.

A genuine harbour setting
Roseville Chase sits on Middle Harbour, with waterfront and water-view blocks of 700 to 1,400m² and prices well above the Ku-ring-gai average. A rebuild lets you design a substantial home around the water and the outlook, which is exactly what people pay for here.
It is a smaller, more exclusive suburb than its train-line cousin Roseville, and a considered rebuild rewards the setting.
Fall, rock and retaining
The main technical work comes from the harbour fall: many lots drop significantly to the water, so a rebuild often needs suspended slabs and substantial retaining rather than a simple slab-on-ground. The Class M ground has sandstone outcrops, so rock can feature on the substructure.
I get a real geotech so the fall, rock and retaining are all costed properly. Heritage controls apply on the older inland streets, and the pre-war stock can carry asbestos and lead paint, so a licensed strip-out leads the demolition.
